Enum DSOperationType

java.lang.Object
  java.lang.Enum<DSOperationType>
      com.smartgwt.client.types.DSOperationType

All Implemented Interfaces:

ValueEnum, java.io.Serializable, java.lang.Comparable<DSOperationType>

public enum DSOperationType
extends java.lang.Enum<DSOperationType>
implements ValueEnum

One of the four basic operations that can be performed on DataSource data: "fetch", "add", "update", "remove". Elsewhere called CRUD operations, where CRUD stands for "create", "retrieve", "update", "delete", which correspond to "add", "fetch", "update" and "remove" in Smart GWT terminology. See DataSourceOperations for a full description.

There is also a fifth operation, "custom". This is any operation that is not one of the four CRUD operations. You can use operations of this type in circumstances where you might otherwise have used a plain RPC.

Store new records

CUSTOM
Perform some arbitrary custom logic that is not a CRUD operation

Method Detail

values

public static DSOperationType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DSOperationType c : DSOperationType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DSOperationType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

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

java.lang.NullPointerException - if the argument is null

getValue

public java.lang.String getValue()

Specified by:

getValue in interface ValueEnum
