All Implemented Interfaces:

java.lang.Iterable, java.util.Collection

public abstract class AbstractFilteredNodeCollection
extends com.phoenixst.plexus.util.AbstractNodeCollection

Extends AbstractNodeCollection to provide support for a predicate. Subclasses must still define their own iterator() and it must already be filtered. This makes it easier to define optimized support for certain predicates in special graph implementations.
