Enum Constant Detail

SAME

public static final NodeRelativePosition SAME

The 2 nodes are the same.

STRICTLY_OVER

public static final NodeRelativePosition STRICTLY_OVER

The first node is over the second one.

There is a path from first node to second one.

STRICTLY_UNDER

public static final NodeRelativePosition STRICTLY_UNDER

The first node is under the second one.

There is a path from second bode to first one.

IN_LOOP

public static final NodeRelativePosition IN_LOOP

There is a loop passing through both nodes.

This should not exist if the graph describes a partial or total order.

UNRELATED

public static final NodeRelativePosition UNRELATED

The 2 nodes are not related.

Method Detail

values

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

Returns:

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

valueOf

public static NodeRelativePosition 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
