Detailed Description

template<typename AuxColl, typename Aux, typename Tag>
class proxy::details::ParallelData< AuxColl, Aux, Tag >

Object to draft parallel data interface.

Template Parameters

AuxColl	type of the parallel data collection
Aux	type of the associated object
Tag	tag this data is labeled with

Allows:

• random access (no index check guarantee)
• forward iteration

Construction is not part of the interface.
