Enum QuadAction

All Implemented Interfaces:

Serializable, Comparable<QuadAction>

public enum QuadAction
extends Enum<QuadAction>

A QuadAction is record of a type of change to a DatasetGraph.

DatasetGraph are sets of quads. An add only affects the state of the DatasetGraph if a quad of the same value was not present, and a delete only affects the state of the DatasetGraph if a quad was present.

A QuadAction can be an ADD or DELETE, indicating a change to the DatasetGraph actually occured (this assumes checking is done - DatasetChanges generators may not check - see implementation for details). Otherwise a NO_ADD, NO_DELETE QuadAction is used.

Method Detail

values

public static QuadAction[] 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 (QuadAction c : QuadAction.values())
    System.out.println(c);

Returns:

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

valueOf

public static QuadAction valueOf(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:

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

NullPointerException - if the argument is null
