Interface GraphLike<T extends TripleLike>

Type Parameters:
T - A TripleLike type used by the graph methods, typically Triple or Quad

public interface GraphLike<T extends TripleLike>
A "graph-like" interface that contains TripleLike statements.

Extended by Graph (for Triple) and Dataset (for Quad).

Unlike Graph and Dataset, this interface can support generalised TripleLike or QuadLike statements, but does not imply semantics like size() or the requirement of mapping RDFTerm instances from different implementations.

As TripleLike do not have a specific Object.equals(Object) semantics, the behaviour of methods like contains(TripleLike) and remove(TripleLike) is undefined for arguments that are not object identical to previously added or returned TripleLike statements.
