inline

Apply a PartitioningSolution to an input.

This is not a required part of the InputAdapter interface. However if the Caller calls a Problem method to redistribute data, it needs this method to perform the redistribution.

Parameters

in	An input object with a structure and assignment of of global Ids to processes that matches that of the input data that instantiated this Adapter.
out	On return this should point to a newly created object with the specified partitioning.
solution	The Solution object created by a Problem should be supplied as the third argument. It must have been templated on user data that has the same global ID distribution as this user data.

Returns: Returns the number of local Ids in the new partition.
