Detailed Description

Network which encapsulates a multi-threaded simulation in one process on a multi-processor machine.

Used for setup and running simulations on one multi-processor machine (single-node multi-thread scenario). Contains interfaces for construction of the network, i.e. adding SimObject objects (neurons, synapses, etc.) and connecting them, and also used for simulation control.

Member Function Documentation

void MultiThreadNetwork::_addObject_	(	const SimObjectFactory &	objFactory,
		const SimEngine::ID &	loc,
		SimObject::ID &	gid
	)			`[virtual]`

The simulation object is added to the network.

The object is added to the list of advancable objects of the network. The network takes over the ownership of the object, i.e. the network will free the memory occupied by the object if necessary.

Parameters:

	obj	pointer to the SimObject simulation object to be added.
	eng	Specifies the (local) simulation engine to which the object should be added.
	id	Resulting identifier of the added object. All four elements (node,engine,type,localid) of the identifier are determined by the network itself during addition. One instance of a simulation object is created by the factory and added at specified simulation engine of the network.
	loc	Specifies the node and local engine where the object should be added to. loc.node is ignored!
	id	The resulting unique identifier (node,engine,type,localid) of the created object.
