public abstract class CompositionBase extends GraphBase
Base class for graphs that are composed of multiple sub-graphs. This is to provide
a home for shared functionality that was previously in Dyadic before
refactoring.

static <T> ClosableIterator<T> |
butNot(ClosableIterator<T> a,
ClosableIterator<? extends T> b)
Answer an iterator over the elements of iterator a that are not members of iterator b.
|
static <T> Predicate<T> |
ifIn(ClosableIterator<T> i)
Answer a
Predicate that will accept any object that is an element of
iterator i. |
static Predicate<Triple> |
ifIn(Graph g)
Answer a
Predicate that will accept any triple that is an edge of
graph g. |
static <T> ExtendedIterator<T> |
recording(ClosableIterator<T> i,
Set<T> seen)
Answer an iterator that will record every element delived by
next() in
the set seen. |
static <T> Predicate<T> |
reject(ClosableIterator<? extends T> i)
Answer a
Predicate that will reject any element that is a member of iterator i. |
static ExtendedIterator<Triple> |
rejecting(ExtendedIterator<Triple> i,
Graph seen)
Answer an iterator over the elements of
i that are not in
the graph seen. |
static ExtendedIterator<Triple> |
rejecting(ExtendedIterator<Triple> i,
Set<Triple> seen)
Answer an iterator over the elements of iterator i that are not in the set
seen. |
