Enum Constant Detail

WHITE

public static final Color WHITE

For coloring vertices or edges white. White is the initial (default) color for vertices and edges.

GRAY

public static final Color GRAY

For coloring vertices or edges gray. Gray is used to indicate that a vertex or edge has been visited but that a method has not yet finished examining the given object.

BLACK

public static final Color BLACK

For coloring vertices or edges black. Black is used to indicate that a method has completed its examiniation of an edge or vertex.

Method Detail

values

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

Returns:

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

valueOf

public static Color 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
