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

	new operator "delete", to go with the new version of operator new.
static void *	operator new (size_t size, GlobalId *&o)
	placement "new", needed for stl.

Public Attributes

	Unique ID within the dueca node.

Static Public Attributes
static const char *const	classname
	The name of this class.
static const uint32_t	magic_check_number
	a "magic" number, hashed out of the class definition, that will be used to check consistency of the sent objects across the dueca nodes.

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.
