Enum FieldType

java.lang.Object

      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 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

Fields of this type can contain any data value and have no default formatting or validation behavior.

Fields of this type are automatically populated by the Smart GWT Server with the current authenticated userId as part of "add" operations.

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

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.

NTEXT
A special field type specifically for use with Unicode data in conjunction with the Microsoft SQL Server database.

PASSWORD
A 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 custom DataSources: a custom DataSource or DMI must implement the "viewFile" and "downloadFile" operationTypes and return a single Record with an byte[] as the field value for the binary field. For more detail see the overview of Binary Fields.

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. 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.

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. The notes about type "modifier" also apply to fields 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

A password field type.

CUSTOM

public static final FieldType CUSTOM

A custom SimpleType field type.

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"

Method Detail

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
