Enum Direction

java.lang.Object

java.lang.Enum<Direction>

com.adobe.granite.socialgraph.Direction

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Direction>

public enum Direction
extends java.lang.Enum<Direction>

Defines relationship directions used when getting relationships from a node. A relationship has a direction from a node's point of view. If a node is the start node of a relationship it will be an OUTGOING relationship from that node's point of view. If a node is the end node of a relationship it will be an INCOMING relationship from that node's point of view. The BOTH direction is used when direction is of no importance, such as "give me all" relationships that are either OUTGOING or INCOMING.

Method Detail

values

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

Returns:

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

valueOf

public static Direction 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
