	)		const

pure virtual

Get the parts belonging to a process.

Parameters

procId	a process rank
numParts	on return will be set the number of parts belonging to the process.
parts	on return will be a pointer to the parts assigned to procId

Implemented in Zoltan2::CoordinateTaskMapper< Adapter, part_t >.
