ValidatorType (Smart GWT EE API 13.0p (2024-11-22))

java.lang.Object
- java.lang.Enum<ValidatorType>
- - com.smartgwt.client.types.ValidatorType

All Implemented Interfaces:

ValueEnum, java.io.Serializable, java.lang.Comparable<ValidatorType>
```
public enum ValidatorType
extends java.lang.Enum<ValidatorType>
implements ValueEnum
```
Used to name a validator or reference a standard, built-in Validator - see list below.
To make use of a standard validator type for a field in a DataSource, or DynamicForm instance, specify the validators property to an array containing a validator definition where the type property is set to the appropriate type.
A custom error message can be specified for any validator type by setting the errorMessage property on the validator definition object, and some validator types make use of additional properties on the validator definition object such as max or min.
For example, to use the integerRange validator type:

field:{ validators:[ {type:"integerRange", min:1, max:100} ] }
Custom validators can be reused on the client by adding them to the global validator list, via the Validator.addValidatorDefinition() method.

- Enum Constant Detail
  - ISBOOLEAN
```
public static final ValidatorType ISBOOLEAN
```
    Validation will fail if this field is non-empty and has a non-boolean value.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "isBoolean".
  - ISSTRING
```
public static final ValidatorType ISSTRING
```
    Validation will fail if the value is not a string value.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "isString".
  - ISINTEGER
```
public static final ValidatorType ISINTEGER
```
    Tests whether the value for this field is a whole number. If validator.convertToInteger is true, float values will be converted into integers and validation will succeed.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "isInteger".
  - ISFLOAT
```
public static final ValidatorType ISFLOAT
```
    Tests whether the value for this field is a valid floating point number.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "isFloat".
  - ISFUNCTION
```
public static final ValidatorType ISFUNCTION
```
    Tests whether the value for this field is a valid expression or function; if it is valid, creates a stringMethod object with the value and set the resultingValue to the StringMethod.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "isFunction".
  - REQUIREDIF
```
public static final ValidatorType REQUIREDIF
```
    RequiredIf type validators should be specified with an expression property set to a stringMethod, which takes four parameters:
    - item - the DynamicForm item on which the error occurred (may be null)
    - validator - a pointer to the validator object
    - value - the value of the field in question
    - record - the "record" object - the set of values being edited by the widget
    When validation is performed, the expression will be evaluated (or executed). If it returns true, the field will be treated as a required field, so validation will fail if the field has no value, or, in the case of a FileItem or UploadItem and if client-side validation is supported by the browser, if no file is selected for upload or the selected file is empty.
    To allow server-side enforcement, a required validator can be used instead. With the exception of "binary" fields, conditional criteria can be specified with the applyWhen property.
    See Conditionally Required Example.
    Moreover, the expression provided needs to be in JavaScript, so to use this API, you should be familiar with JavaScript and Smart GWT APIs. A pure-Java alternative is to add a RequiredIfValidator on the DynamicForm or ListGrid where validation is required.
    NOTE: A requiredIf validator cannot be used to guarantee that a non-empty file is uploaded. The user's browser might not support client-side file validation. Using a requiredIf validator on a "binary" field may be appropriate in scenarios where the application does not technically require a non-empty file to be uploaded by the user. For example, in a bug tracking application, a file upload may be required if the "Have a test case?" checkbox is checked, but the value of the "Have a test case?" checkbox is not actually saved by the application; instead, whether the user is providing a test case is inferred by whether a non-empty test case file was uploaded.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "requiredIf".
  - MATCHESFIELD
```
public static final ValidatorType MATCHESFIELD
```
    Tests whether the value for this field matches the value of some other field. The field to compare against is specified via the otherField property on the validator object (should be set to a field name).
    See Match Value Example.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "matchesField".
  - EQUALS
```
public static final ValidatorType EQUALS
```
    Tests whether the value for this field matches some value specified via value.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "equals".
  - NOTEQUAL
```
public static final ValidatorType NOTEQUAL
```
    Tests whether the value for this field does not match some value specified via value.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "notEqual".
  - ISONEOF
```
public static final ValidatorType ISONEOF
```
    Tests whether the value for this field matches any value from an arbitrary list of acceptable values. The set of acceptable values is specified via the list property on the validator, which should be set to an array of values. If validator.list is not supplied, the valueMap for the field will be used. If there is no valueMap, not providing validator.list is an error.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "isOneOf".
  - INSET
```
public static final ValidatorType INSET
```
    Tests whether the value for this field matches any value from an arbitrary list of acceptable values. The set of acceptable values is specified via the list property on the validator, which should be set to an array of values. If validator.list is not supplied, the valueMap for the field will be used. If there is no valueMap, not providing validator.list is an error.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "inSet".
  - NOTINSET
```
public static final ValidatorType NOTINSET
```
    Tests whether the value for this field does not match any value from an arbitrary list of unacceptable values. The set of unacceptable values is specified via the list property on the validator, which should be set to an array of values. Not providing validator.list is an error.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "notInSet".
  - INTEGERRANGE
```
public static final ValidatorType INTEGERRANGE
```
    Tests whether the value for this field is a whole number within the range specified. The max and min properties on the validator are used to determine the acceptable range, inclusive. To specify the range as exclusive of the min/mix values, set exclusive to true.
    See Built-ins Example.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "integerRange".
  - LENGTHRANGE
```
public static final ValidatorType LENGTHRANGE
```
    This validator type applies to string values only. If the value is a string value validation will fail if the string's length falls outside the range specified by validator.max and validator.min.
    Note that non-string values will always pass validation by this validator type.
    Note that the errorMessage for this validator will be evaluated as a dynamicString - text within ${...} will be evaluated as JS code when the message is displayed, with max and min available as variables mapped to validator.max and validator.min.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "lengthRange".
  - CONTAINS
```
public static final ValidatorType CONTAINS
```
    Determine whether a string value contains some substring specified via validator.substring.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "contains".
  - DOESNTCONTAIN
```
public static final ValidatorType DOESNTCONTAIN
```
    Determine whether a string value does not contain some substring specified via validator.substring.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "doesntContain".
  - SUBSTRINGCOUNT
```
public static final ValidatorType SUBSTRINGCOUNT
```
    Determine whether a string value contains some substring multiple times. The substring to check for is specified via validator.substring. The validator.operator property allows you to specify how to test the number of substring occurrences. Valid values for this property are ==, !=, <, <=, >, >=.
    The number of matches to check for is specified via validator.count.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "substringCount".
  - REGEXP
```
public static final ValidatorType REGEXP
```
    regexp type validators will determine whether the value specified matches a given regular expression. The expression should be specified on the validator object as the expression property.
    See Regular Expression Example.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "regexp".
  - MASK
```
public static final ValidatorType MASK
```
    Validate against a regular expression mask, specified as validator.mask. If validation is successful a transformation can also be specified via the validator.transformTo property. This should be set to a string in the standard format for string replacement via the native JavaScript replace() method.
    See Value Transform Example.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "mask".
  - DATERANGE
```
public static final ValidatorType DATERANGE
```
    Tests whether the value for a date field is within the range specified. Range is inclusive, and is specified via validator.min and validator.max, which should be specified in XML Schema date format or as a live JavaScript Date object (for client-only validators only). To specify the range as exclusive of the min/mix values, set exclusive to true.
    Note that the errorMessage for this validator will be evaluated as a dynamicString - text within ${...} will be evaluated as JS code when the message is displayed, with max and min available as variables mapped to validator.max and validator.min.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "dateRange".
  - FLOATLIMIT
```
public static final ValidatorType FLOATLIMIT
```
    Validate a field as a valid floating point value within a value range. Range is specified via validator.min and validator.max. Also checks precision, specified as number of decimal places in validator.precision. If validator.roundToPrecision is set a value that doesn't match the specified number of decimal places will be rounded to the nearest value that does.
    For backwards compatibility only. Use "floatRange" and/or "floatPrecision" instead.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "floatLimit".
  - FLOATRANGE
```
public static final ValidatorType FLOATRANGE
```
    Tests whether the value for this field is a floating point number within the range specified. The max and min properties on the validator are used to determine the acceptable range, inclusive. To specify the range as exclusive of the min/mix values, set exclusive to true.
    Note that the errorMessage for this validator will be evaluated as a dynamicString - text within ${...} will be evaluated as JS code when the message is displayed, with max and min available as variables mapped to validator.max and validator.min.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "floatRange".
  - FLOATPRECISION
```
public static final ValidatorType FLOATPRECISION
```
    Tests whether the value for this field is a floating point number with the appropriate number of decimal places - specified in validator.precision If the value is of higher precision and validator.roundToPrecision is specified, the value will be rounded to the specified number of decimal places and validation will pass, otherwise validation will fail.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "floatPrecision".
  - REQUIRED
```
public static final ValidatorType REQUIRED
```
    A non-empty value is required for this field to pass validation.
    In the case of a "binary" field, a non-empty file must be uploaded.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "required".
  - READONLY
```
public static final ValidatorType READONLY
```
    Disallows changes to this field, based on the Validator.applyWhen condition.
    In addition to server-side enforcement, this validator will automatically cause editors for the field to become read-only, by rendering in a disabled appearance, readOnly appearance, or even by becoming hidden.
    The appearance of the read-only field can be controlled by validator.fieldAppearance. See FieldAppearance for choices. If fieldAppearance is not specified, the default is "readOnly".
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "readOnly".
  - VISIBILITY
```
public static final ValidatorType VISIBILITY
```
    Change the visibility of this field.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "visibility".
  - ENABLE
```
public static final ValidatorType ENABLE
```
    Change the enable/disable state of this field.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "enable".
  - ISUNIQUE
```
public static final ValidatorType ISUNIQUE
```
    Returns true if the value for this field is unique. The uniqueness check is performed across the whole DataSource unless you specify property validator.criteriaFields as a comma-separated string of field names; in that case, the uniqueness check is done in the context of those extra criteria, allowing you to check, for example, whether an employee number is unique for the department and location found on the record being validated. By default the uniqueness check is not case sensitive but this can be controlled through the caseSensitive attribute. You can specify the operation to use for the uniqueness check with the operationId attribute.
    Validators of this type have requiresServer set to true and do not run on the client, unless all of the following are true:
    - The validation is run in the context of a DataBoundComponent or ValuesManager bound to some DataSource.
    - The DataSource is either clientOnly:true or cacheAllData: true and all data is loaded
    - The item is made available to the validator. Note that the item is not be available during a save performed without a form (eg programmatic save), or if the field is not available in the form.
    Note when isUnique validator is executed as part of validation process during update operation, it will perform uniqueness check only for single row updates. If update targets multiple records, then isUnique validator will be skipped. If uniqueness check is needed when updating multiple records, consider using custom DMI approach to add this check manually.
    See uniqueCheckValidation.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "isUnique".
  - HASRELATEDRECORD
```
public static final ValidatorType HASRELATEDRECORD
```
    Returns true if the record implied by a relation exists. The relation can be derived automatically from the DataSourceField.foreignKey attribute of the field being validated, or you can specify it manually via validator.relatedDataSource and validator.relatedField.
    You can specify at DataSource level that this validator should be automatically applied to all fields that specify a foreignKey - see DataSource.validateRelatedRecords.
    By default the uniqueness check is not case sensitive but this can be controlled through the caseSensitive attribute.
    Validators of this type have requiresServer set to true and do not run on the client.
    Note that this validation is generally unnecessary for data coming from a UI. The typical UI uses a SelectItem or ComboBoxItem with an optionDataSource for user entry, such that the user can't accidentally enter a related record if that doesn't exist, and a typical SQL schema will include constraints that prevent a bad insert if the user attempts to circumvent the UI. The primary purpose of declaring this validation explicitly is to provide clear, friendly error messages for use cases such as BatchUploader, where values aren't individually chosen by the user. See also the example Related Records.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "hasRelatedRecord".
  - MAXFILESIZE
```
public static final ValidatorType MAXFILESIZE
```
    This validator type is not for direct usage, instead DataSourceField.maxFileSize can be set and maxFileSize validator will be added automatically. Use maxFileSizeExceededMessage to customize validation error message.
    In supported browsers (Internet Explorer 10+, Chrome, Firefox, Safari 6+, Opera 11.1+), returns true if the file(s) selected by the user are not larger than the field's DataSourceField.maxFileSize. If not supported by the browser, the validator will always return true.
    Note that server-side enforcement of the maxFileSize is always required because the user's browser might not support client-side file size checks. Also, any client-side check can be bypassed by a malicious user.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "maxFileSize".
  - CUSTOM
```
public static final ValidatorType CUSTOM
```
    Custom client-side validator. Use by creating a subclass of Custom.CustomValidator and implementing the condition method.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "custom".
  - SERVERCUSTOM
```
public static final ValidatorType SERVERCUSTOM
```
    Custom server-side validator that either evaluates the Velocity expression provided in serverCondition (see Velocity Expression Example) or makes DMI call to serverObject to evaluate condition (see DMI Validation Example).
    Validators of this type have requiresServer set to true and do not run on the client.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "serverCustom".
