Enum FieldType

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

All Implemented Interfaces:

ValueEnum, Serializable, Comparable<FieldType>

public enum FieldType
extends Enum<FieldType>
implements ValueEnum

The types listed below are built-in types that databound 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 JavaScript object model.

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 foreignKey, not a nested structure declaration.

Enum Constant Summary

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
A custom SimpleType field type.

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.

INTENUM
An enum whose values are numeric.

LINK
A string representing a well-formed URL.

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.

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.

PASSWORD
Password field type

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.

TEXT
Generic text, e.g.

TIME
A time of day, with no date.

Enum Constant Detail

TEXT

public static final FieldType TEXT

Generic text, e.g. John Doe. This is the default field type. Use field.length to set length.

BOOLEAN

public static final FieldType BOOLEAN

A boolean value, e.g. true

INTEGER

public static final FieldType INTEGER

A whole number, e.g. 123

FLOAT

public static final FieldType FLOAT

A floating point (decimal) number, e.g. 1.23

DATE

public static final FieldType DATE

A logical date, with no time value (such as a holiday or birthday). Represented on the client as a JavaScript Date object with all time fields set to zero in browser local time. Transmitted in UTC/GMT by default. See DateFormatAndStorage for more information on date display and serialization formats. See also Date for Smart GWT extensions to the Date object.

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).

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 and Date for Smart GWT extensions to the Date object.

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.

INTENUM

public static final FieldType INTENUM

An enum whose values are numeric.

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 sequenceName.

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).

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.

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 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 non-SQL DataSources: a non-SQL DataSource should provide an instance of the Java type InputStream as a field value in DSResponse.data in order to allow Smart GWT to download the file.

IMAGEFILE

public static final FieldType IMAGEFILE

Binary data comprising an image.

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.

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.

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.

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.

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.

PASSWORD

public static final FieldType PASSWORD

Password field type

CUSTOM

public static final FieldType CUSTOM

A custom SimpleType field type.
