Enum Constant Detail

WHITE

public static final DepthFirstIterator.VisitColor WHITE

Vertex has not been returned via iterator yet.

GRAY

public static final DepthFirstIterator.VisitColor GRAY

Vertex has been returned via iterator, but we're not done with all of its out-edges yet.

BLACK

public static final DepthFirstIterator.VisitColor BLACK

Vertex has been returned via iterator, and we're done with all of its out-edges.

Method Detail

values

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

Returns:

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

valueOf

public static DepthFirstIterator.VisitColor 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
