OUT

Method Summary

boolean	contains(RelationDirection d) Returns true if this direction "contains" the specified one, that is, either it's equal to it, or this direction is BOTH
RelationDirection	inverse() Inverts the direction of the relation.
RelationDirection	sum(RelationDirection d) Adds the current direction
static RelationDirection	valueOf(String name) Returns the enum constant of this type with the specified name.
static RelationDirection[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

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

Returns:

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

valueOf

public static RelationDirection 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

sum

public RelationDirection sum(RelationDirection d)

Adds the current direction

Parameters:

d -

Returns:

contains

public boolean contains(RelationDirection d)

Returns true if this direction "contains" the specified one, that is, either it's equal to it, or this direction is BOTH

Parameters:

d -

Returns:

inverse

public RelationDirection inverse()

Inverts the direction of the relation. Turns IN into OUT and vice-versa, NONE and BOTH are not changed

Returns:
