contributesTo

public final boolean contributesTo(String namespace)

Description copied from interface: VertexProvider

This boolean returns true if the vertices in this provider are intended to contribute to or overlay another namespace

Specified by:

contributesTo in interface EdgeProvider

Specified by:
