FieldType (Smart GWT EE API 14.0p (2026-01-20))

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

All Implemented Interfaces:

ValueEnum, java.io.Serializable, java.lang.Comparable<FieldType>
```
public enum FieldType
extends java.lang.Enum<FieldType>
implements ValueEnum
```
The types listed below are built-in types that databound\n components understand and treat specially (using type-specific form controls, validators, formatters, sorting logic, etc).
You can declare custom types via SimpleType.create(), with settings that will influence DataBound components. You can also create your own subclasses of databound components to add further custom, reusable behaviors based on field.type.
field.type can also be the ID of another DataSource, which allows you to model nested structures such as XML documents (in fact, XMLTools.loadXMLSchema() models XML schema in this way). Nested DataSource declarations affect how XML and JSON data is deserialized into JavaScript objects in the client-side integration pipeline, so that you can load complex XML documents and have them deserialized into a correctly typed nested data structure.
Note: to declare related but separate objects, as in an "Account" object that can be related to both a "Contact" object and "Order" objects, use DataSourceField.foreignKey, not a nested structure declaration.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`ANY` Fields of this type can contain any data value and have no default formatting or validation behavior.
`BINARY` Arbitrary binary data.
`BOOLEAN` A boolean value, e.g.
`CREATOR` Fields of this type are automatically populated by the Smart GWT Server with the current authenticated userId as part of "add" operations.
`CREATORTIMESTAMP` Fields of this type are automatically populated by the Smart GWT Server with the current date and time as part of an "add" operation (when the record is first created).
`CUSTOM` Synonymous with "any".
`DATE` A logical date, with no time value (such as a holiday or birthday).
`DATETIME` A date and time, accurate to the `second`.
`ENUM` A text value constrained to a set of legal values specified by the field's `valueMap`, as though a `ValidatorType` of "isOneOf" had been declared.
`FLOAT` A floating point (decimal) number, e.g.
`IMAGE` A string representing a well-formed URL that points to an image.
`IMAGEFILE` Binary data comprising an image.
`INTEGER` A whole number, e.g.

  - TIME
```
public static final FieldType TIME
```
    A time of day, with no date. Represented on the client as a JavaScript Date object in UTC/GMT by default (see also DateFormatAndStorage and the String class).
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "time".
  - DATETIME
```
public static final FieldType DATETIME
```
    A date and time, accurate to the second. Represented on the client as a JavaScript Date object. See also DateFormatAndStorage.

  - ENUM
```
public static final FieldType ENUM
```
    A text value constrained to a set of legal values specified by the field's valueMap, as though a ValidatorType of "isOneOf" had been declared.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "enum".
  - INTENUM
```
public static final FieldType INTENUM
```
    An enum whose values are numeric.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "intEnum".
  - SEQUENCE
```
public static final FieldType SEQUENCE
```
    If you are using the Smart GWT SQL datasource connector, a sequence is a unique, increasing whole number, incremented whenever a new record is added. Otherwise, sequence behaves identically to integer. This type is typically used with field.primaryKey to auto-generate unique primary keys. See also DataSourceField.sequenceName and DataSource.sequenceMode
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "sequence".
  - LINK
```
public static final FieldType LINK
```
    A string representing a well-formed URL. Some components will render this as an HTML link (using an anchor tag for example).
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "link".
  - IMAGE
```
public static final FieldType IMAGE
```
    A string representing a well-formed URL that points to an image. Some components will render an IMG tag with the value of this field as the 'src' attribute to render the image.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "image".
  - BINARY
```
public static final FieldType BINARY
```
    Arbitrary binary data. When this field type is present, three additional fields are automatically generated. They are: <fieldName>_filename, <fieldName>_filesize, and <fieldName>_date_created where <fieldName> is the value of the name attribute of this field. These fields are marked as DataSourceField.hidden:true to suppress their rendering by default. You can show one or more of these fields by specifying the field with a hidden:false override in the fields array of the databound component. Stream / view file support for custom DataSources: a custom DataSource or DMI must implement the "viewFile" and "downloadFile" operationTypes and return a single Record with a byte[] as the field value for the binary field. For more detail see the overview of Binary Fields.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "binary".
  - IMAGEFILE
```
public static final FieldType IMAGEFILE
```
    Binary data comprising an image. Causes ViewFileItem to be used when the field is displayed in a form, allowing the image to optionally be displayed inline.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "imageFile".
  - ANY
```
public static final FieldType ANY
```
    Fields of this type can contain any data value and have no default formatting or validation behavior. This is useful as the parent type for SimpleTypes where you do not want any of the standard validation or formatting logic to be inherited from the standard built-in types.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "any".
  - CUSTOM
```
public static final FieldType CUSTOM
```
    Synonymous with "any".
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "custom".
  - MODIFIER
```
public static final FieldType MODIFIER
```
    Fields of this type are automatically populated by the Smart GWT Server with the current authenticated userId as part of "add" and "update" operations. By default, fields of this type are hidden and not editable; the server ignores any value that the client sends in a field of this type (but see also writeToGeneratedFields). Note that the "authenticated user" can be set explicitly on the server-side RPCManager using the setUserId() method, or it can come from the servlet API if you are using its built-in authentication scheme. See the server-side Javadocs for RPCManager.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "modifier".
  - MODIFIERTIMESTAMP
```
public static final FieldType MODIFIERTIMESTAMP
```
    Fields of this type are automatically populated by the Smart GWT Server with the current date and time as part of "add" and "update" operations. By default, fields of this type are hidden and not editable; the server ignores any value that the client sends in a field of this type (but see also writeToGeneratedFields).
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "modifierTimestamp".
  - CREATOR
```
public static final FieldType CREATOR
```
    Fields of this type are automatically populated by the Smart GWT Server with the current authenticated userId as part of "add" operations. By default, fields of this type are hidden and not editable; the server ignores any value that the client sends in a field of this type. (but see also writeToGeneratedFields). The notes about type "modifier" also apply to fields of this type.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "creator".
  - CREATORTIMESTAMP
```
public static final FieldType CREATORTIMESTAMP
```
    Fields of this type are automatically populated by the Smart GWT Server with the current date and time as part of an "add" operation (when the record is first created). By default, fields of this type are hidden and not editable; the server ignores any value that the client sends in a field of this type (but see also writeToGeneratedFields).
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "creatorTimestamp".
  - PASSWORD
```
public static final FieldType PASSWORD
```
    Same as "text", but causes PasswordItem to be used by default for editing (hides typed-in value), and defaults storeWithhash to "bcrypt" (affecting server operations).
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "password".
  - NTEXT
```
public static final FieldType NTEXT
```
    A special field type specifically for use with Unicode data in conjunction with the Microsoft SQL Server database. Field type "ntext" implies the use of sqlStorageStrategy "ntext"; other than that, this type is identical to "text"
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "ntext".
  - LOCALEINT
```
public static final FieldType LOCALEINT
```
    An integer number with locale-based formatting, e.g. 12,345,678. See Localized Number Formatting for more info.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "localeInt".
  - LOCALEFLOAT
```
public static final FieldType LOCALEFLOAT
```
    A float number with locale-based formatting, e.g. 12,345.67. See Localized Number Formatting for more info.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "localeFloat".
  - LOCALECURRENCY
```
public static final FieldType LOCALECURRENCY
```
    A float number with locale-based formatting and using currency symbol, e.g. $12,345.67. See Localized Number Formatting for more info.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "localeCurrency".
  - PHONENUMBER
```
public static final FieldType PHONENUMBER
```
    A telephone number. Uses FormItem.browserInputType "tel" to hint to the device to restrict input. On most mobile devices that have software keyboards, this cause a specialized keyboard to appear which only allows entry of normal phone numbers. When displayed read-only, a "phoneNumber" renders as an HTML link with the "tel:" URL scheme, which will invoke the native phone dialing interface on most mobile devices. In addition, the CSS style "sc_phoneNumber" is applied.
    By default, "phoneNumber" fields do not include validators, however the following validator definition would limit to digits, dashes and the "+" character: xml:
    <validator type="regexp" expression="^($?\+?[0-9]*$?)?[0-9_\- ]*$" errorMessage="Phone number should be in the correct format e.g. +#(###)###-##-##" />
    or directly in Java:
```
  RegExpValidator v = new RegExpValidator();
  v.setType(ValidatorType.REGEXP);
  v.setErrorMessage("Phone number should be in the correct format e.g. +#(###)###-##-##");
  v.setExpression("^(\$?\\+?[0-9]\*$?)?[0-9_\\- \$\$]*$");
  
```
    and adding "#" and "*" to the regular expressions above would allow for users to enter special keys sometimes used for extension numbers or pauses
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "phoneNumber".
