getTypedDependencyChains

public static Counter<java.util.List<TypedDependency>> getTypedDependencyChains(java.util.List<TypedDependency> deps,
                                                                                int maxLength)

dependencyIndexComparator

public static java.util.Comparator<Dependency> dependencyIndexComparator()

A Comparator for Dependencies based on their dependent annotation. It will only work if the Labels at the ends of Dependencies have an index().

Returns:

A Comparator for Dependencies
