Constructor Detail

IsolatedVertexPredicate

protected IsolatedVertexPredicate()

This constructor is protected in order to keep equals working by retaining only one instance. (Currently, since there can only be one instance, equals trivially returns true. If this class is extended, be careful to write equals correctly.)

Method Detail

getInstance

public static IsolatedVertexPredicate getInstance()

Returns an instance of this class.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

evaluateVertex

public boolean evaluateVertex(ArchetypeVertex v)

Returns true if the argument is a Vertex whose degree is 0.
