When we are reflecting local data, this function is called to let the object manager know that we have locally requested updates for a class/set of attributes.

As a result, we will call processProvideUpdate for all relevant objects.

virtual void DtHlaObjectManager::processProvideUpdate	(	RTI::ObjectHandle	id,
		const RTI::AttributeHandleSet &	theAttributes
	)		`[virtual]`

Process RTI's provideUpdate service.

virtual void DtHlaObjectManager::setRegionsForRegister	(	int	numAttrs,
		RTI::AttributeHandle *	attrs,
		RTI::Region **	regions
	)		`[virtual]`

By calling setRegionsForRegister, you are telling VR-Link that until you call setRegionsForRegister again (or call setNoRegionsForRegister), VR-Link should use the DDM version of registerObjectInstance whenever it registers an object for you.

The specified arguments will be passed to the RTI. (VR-Link typically registers an object from within a DtObjectPublisher constructor). In order to restore VR-Link back to the default state, when registers are done with the non-DDM version of registerObjectInstance, call setNoRegionsForRegister. attrs is an array of numAttrs attribute handles, regions is an array of numAttrs pointers to RTI::regions. The lifetime of the arrays must extend through the time that the register occurs. Deletion of the arrays is the caller's responsibility. JIMK REVISIT -- implement DDM
