Static Public Member Functions
static void *	operator new (size_t size)

Detailed Description

This class defines an ID pair, consisting of a location id, identifying a participating dueca node, and an object id, identifying an object (or channel) created in that node.

The ObjectManager maintains a list of references to local objects, indexed on the object id, the ChannelManager does the same for channels.

Local and remote queries for an object, defined by its name and the entity in which it participates, are returned with a GlobalId

Member Function Documentation

operator new()

static void * dueca::GlobalId::operator new ( size_t size )

static

new operator "new", which places objects not on a heap, but in one of the memory arenas.

This to speed up memory management.

packDataDiff()

void dueca::GlobalId::packDataDiff	(	::dueca::AmorphStore &	s,
		const GlobalId &	ref ) const

packs the GlobalId into amorphous storage.

only differences with a previous object are packed.
