Method Detail

getVertexNamespace

public String getVertexNamespace()

Description copied from interface: VertexProvider

A string used to identify references belonging to this provider May only contain characters that make for a reasonable Java identifier such as letters digits and underscore (no colons, periods, commas etc.)

Specified by:

getVertexNamespace in interface VertexProvider

contributesTo

public 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 VertexProvider

Parameters:

namespace - the namespace of a provider

Returns:

true if this provider contributes the the given namespace, false otherwise. Should return false when passing in its own namepace. A provider doesn't contribute to itself.
