supportsDirectObjects

public boolean supportsDirectObjects()

Description copied from interface: GraphComputer.Features

Supports VertexProgram and MapReduce parameters to be direct referenced Java objects (no serialization required). This is typically true for single machine graph computer engines. For cluster oriented graph computers, this is typically false.
