All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Graphs.TransitiveClosureSelfLoopStrategy>

Enclosing class:

Graphs

public static enum Graphs.TransitiveClosureSelfLoopStrategy
extends java.lang.Enum<Graphs.TransitiveClosureSelfLoopStrategy>

A strategy for adding self-loops to the transitive closure graph. All strategies preserve self-loops that are present in the original graph.

The strategies differ based on how they define "cycle incident to a node".

Enum Constant Summary

Enum Constants

Enum Constant	Description
ADD_SELF_LOOPS_ALWAYS	Add a self-loop to each node in the original graph; this is based on a definition of "cycle incident to a node" that includes zero-length cycles.
ADD_SELF_LOOPS_FOR_CYCLES	Add a self-loop to each node that is incident to a cycle of length one or greater in the original graph.

Method Summary

Modifier and Type	Method	Description
static Graphs.TransitiveClosureSelfLoopStrategy	valueOf(java.lang.String name)	Returns the enum constant of this type with the specified name.
static Graphs.TransitiveClosureSelfLoopStrategy[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

ADD_SELF_LOOPS_ALWAYS

public static final Graphs.TransitiveClosureSelfLoopStrategy ADD_SELF_LOOPS_ALWAYS

Add a self-loop to each node in the original graph; this is based on a definition of "cycle incident to a node" that includes zero-length cycles. This matches the behavior of the now-deprecated Graphs.transitiveClosure(Graph) method.

ADD_SELF_LOOPS_FOR_CYCLES

public static final Graphs.TransitiveClosureSelfLoopStrategy ADD_SELF_LOOPS_FOR_CYCLES

Add a self-loop to each node that is incident to a cycle of length one or greater in the original graph.

Method Detail

values

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

Returns:

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

valueOf

public static Graphs.TransitiveClosureSelfLoopStrategy 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
