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.

DATERANGE Tests whether the value for a date field is within the range specified.
DOESNTCONTAIN Determine whether a string value does not contain some substring specified via validator.substring.
FLOATLIMIT Validate a field as a valid floating point value within a value range.
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.
FLOATRANGE Tests whether the value for this field is a floating point number within the range specified.
HASRELATEDRECORD Returns true if the record implied by a relation exists.
INTEGERRANGE Tests whether the value for this field is a whole number within the range specified.
ISBOOLEAN Validation will fail if this field is non-empty and has a non-boolean value.
ISFLOAT Tests whether the value for this field is a valid floating point number.
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.
ISINTEGER Tests whether the value for this field is a whole number.
ISONEOF Tests whether the value for this field matches any value from an arbitrary list of acceptable values.
ISSTRING Validation will fail if the value is not a string value.

REGEXP regexp type validators will determine whether the value specified matches a given regular expression.
REQUIRED A non-empty value is required for this field to pass validation.
REQUIREDIF RequiredIf type validators should be specified with an expression property set to a stringMethod, which takes three 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.
SERVERCUSTOM Custom server-side validator that either evaluates the Velocity expression provided in serverCondition (see velocityValidation) or makes DMI call to serverObject to evaluate condition (see dmiValidation).

Enum Constant Detail

ISBOOLEAN

public static final ValidatorType ISBOOLEAN

Validation will fail if this field is non-empty and has a non-boolean value.

ISSTRING

public static final ValidatorType ISSTRING

Validation will fail if the value is not a string value.

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.

ISFLOAT

public static final ValidatorType ISFLOAT

Tests whether the value for this field is a valid floating point number.

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.

REQUIREDIF

public static final ValidatorType REQUIREDIF

RequiredIf type validators should be specified with an expression property set to a stringMethod, which takes three 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.

To allow server-side enforcement, a required validator can be used instead. Conditional criteria can be specified with the applyWhen property.

See Conditionally Required Example.

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.

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.

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.

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.

CONTAINS

public static final ValidatorType CONTAINS

Determine whether a string value contains some substring specified via validator.substring.

DOESNTCONTAIN

public static final ValidatorType DOESNTCONTAIN

Determine whether a string value does not contain some substring specified via validator.substring.

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.

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.

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.

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.

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.

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.

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.

REQUIRED

public static final ValidatorType REQUIRED

A non-empty value is required for this field to pass validation.

READONLY

public static final ValidatorType READONLY

Change the state/appearance of this field. Desired appearance is specified via the fieldAppearance property on the validator object. See FieldAppearance type for choices.

If fieldAppearance is not specified, the default is "readOnly".

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.

Validators of this type have requiresServer set to true and do not run on the client.

See uniqueCheckValidation.

HASRELATEDRECORD

public static final ValidatorType HASRELATEDRECORD

Returns true if the record implied by a relation exists. The relation can be derived automatically from the 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 validateRelatedRecords.

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.

SERVERCUSTOM

public static final ValidatorType SERVERCUSTOM

Custom server-side validator that either evaluates the Velocity expression provided in serverCondition (see velocityValidation) or makes DMI call to serverObject to evaluate condition (see dmiValidation).

Validators of this type have requiresServer set to true and do not run on the client.
