Detailed Description

Network abstraction.

The structure of the network is maintained by the ytGraph instance. The any type of ytGraph implementations can be used.

ytPCGraph

Known properties

order: The topological order of the node indices. If the network is dag, the edges only from a node with the smaller order to one with larger the order exist. The i-th value represents the node index at the i-th order. See ytRNDGraph.

Member Function Documentation

◆ ytNetwork_addNode()

void ytNetwork_addNode	(	ytNetwork *	this,
		ytNode *	node )

Adds the ytNode instance.

Note that this does not add a node into the ytGraph instance set to this network.

◆ ytNetwork_delete()

void ytNetwork_delete ( ytNetwork * this )

Deletes the ytNetwork instance.

Parameters

this	pointer to the ytNetwork instance to delete.

◆ ytNetwork_findNode()

int ytNetwork_findNode	(	const ytNetwork *	this,
		const char *	name )

Returns the index of the node which has the specified name.

Parameters

this	pointer to the ytNetwork instance.
name	name of node to find.

Returns: index of node whose name is name, or -1 if not found.

◆ ytNetwork_getEdge()

ytEdge * ytNetwork_getEdge	(	ytNetwork *	this,
		int	u,
		int	v )

Returns the ytEdge instance.

If the ytEdge instance is not set for the specified edge, new instance is genereted and returned.

◆ ytNetwork_getEdgeConst()

ytEdge * ytNetwork_getEdgeConst	(	const ytNetwork *	this,
		int	u,
		int	v )

Returns the ytEdge instance.

Note that this may return a NULL pointer.

Returns: ytEdge instance or NULL if no edge properties are found for the edge.

◆ ytNetwork_getNode()

ytNode * ytNetwork_getNode	(	const ytNetwork *	this,
		int	j )

Returns the ytNode instance at the specified index.

Parameters

this
j	index of the node to return.

◆ ytNetwork_getProperty()

ytObject * ytNetwork_getProperty	(	const ytNetwork *	this,
		const char *	key )

Returns the property value associated with the specified key.

Parameters

this	pointer to the ytNetwork instance.
key	key of the property to return.

Returns: property value associated with the key.

◆ ytNetwork_maxParents()

int ytNetwork_maxParents ( const ytNetwork * this )

Returns the maximum number of parents.

Parameters

this

◆ ytNetwork_MPI_Bcast()

void ytNetwork_MPI_Bcast	(	ytNetwork **	pNetwork,
		int	root,
		MPI_Comm	comm )

[MPI] Broadcasts the ytNetwork instance with MPI.

NOTE: Only the MPI-enabled library supports this routine.

Parameters

[in,out]	network	pointer of pointer to the ytNetwork instance. For the root rank, it specifies the instance to send. Otherwise, it specifies the pointer to receive it. If the pointer is non-NULL in non-root rank processes, the instance will be deleted before receiving the broadcasted instance.
	root	root rank in the communicator to broadcast. Other ranks receive the broadcasted instance.
	comm	MPI communicator.

◆ ytNetwork_removeEdge()

ytEdge * ytNetwork_removeEdge	(	ytNetwork *	this,
		int	u,
		int	v )

Removes an edge.

This also removes edge in the ytGraph instance set in this ytNetwork instance.

Returns: Removed ytEdge instance, or NULL if not found.

◆ ytNetwork_setEdge()

void ytNetwork_setEdge	(	ytNetwork *	this,
		ytEdge *	edge )

Sets the ytEdge instance.

Note: if the ytEdge instance is already set for this edge, this overwrites the existing one and it will not be freed.

If the edge does not exists in the graph, it automatically adds it. The graph instance needs to be set in the network.

◆ ytNetwork_setNode()

ytNode * ytNetwork_setNode	(	ytNetwork *	this,
		int	j,
		ytNode *	node )

Replaces the ytNode instance.

Returns: Old ytNode instance to be replaced.

◆ ytNetwork_setProperty()

void ytNetwork_setProperty	(	ytNetwork *	this,
		const char *	key,
		ytObject *	value )

Sets a property value with its key.

Parameters

this
key
value
