Method Detail

getEdgePredicate

public org.apache.commons.collections.Predicate getEdgePredicate()

Description copied from interface: DependencyGraphWalker

Get the predicate used to determine if the walker should traverse an edge (or not).

Specified by:

getEdgePredicate in interface DependencyGraphWalker

Returns:

the Predicate that returns true for edges that should be traversed.
