Member Function Documentation

virtual Map::View query	(	Invocable::Handle	hTask,
		Set::View	vSetMembers
	)			`[pure virtual]`

Synchronously invoke the specified task on each of the specified members.

This method will not return until the specified members have completed their processing, failed in their processing, or died trying.

Currently, the client implementation of this interface only supports invocation on the cluster member to which the client is connected. Therefore, the specified Set of Member objects must be NULL.

Parameters:

	hTask	the Invocable object to distribute to the specified members in order to be invoked on those members
	vSetMembers	must be NULL (future use)

Returns:: a Map of result objects keyed by Member object
