## Enum FieldType

- 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.

    - #### 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 "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. 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.

      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. 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.

      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).

      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".
