ytPGraph_addEdge()

void ytPGraph_addEdge	(	ytPGraph *	this,
		int	src,
		int	dst
	)

Adds an edge to the graph.

This does not check whether the src - dst edge exists already in the graph.

Parameters

this
src
dst

ytPGraph_checkEdge()

int ytPGraph_checkEdge	(	const ytPGraph *	this,
		int	src,
		int	dst
	)

Checks if the specified edge exists in the graph.

Parameters

this	pointer to the ytPGraph instance. NULL acceptable. If so, this always returns 0.
src	index of starting node of the edge.
dst	index of ending node of the edge.

Returns

1 if the edge exists, or 0 otherwise.

ytPGraph_clear()

void ytPGraph_clear

(

ytPGraph *

this

)

Removes all the edges.

Parameters

this	pointer to the ytPGraph instance.

ytPGraph_copy()

void ytPGraph_copy	(	ytPGraph *	this,
		const ytPGraph *	src
	)

Copies edges to this graph.

The current edges in this graph are removed, then edges in src are copied into this graph.

Parameters

this
src

ytPGraph_copyGraph()

ytPGraph_copyGraph()

void ytPGraph_copyGraph	(	ytPGraph *	this,
		const ytGraph *	src
	)

Copies edges to this graph.

The current edges in this graph are removed, then edges in src are copied into this graph.

Parameters

this
src

ytPGraph_delete()

void ytPGraph_delete

(

ytPGraph *

this

)

ytPGraph_getParent()

int ytPGraph_getParent	(	const ytPGraph *	this,
		int	j,
		int	k
	)

Returns the parent index of the node.

Parameters

this	pointer to the ytPGraph instance.
j	node index.
k	parent index.

Returns

index of the k -th parent of the j -th node.

ytPGraph_numNodes()

int ytPGraph_numNodes

(

const ytPGraph *

this

)

Returns the number of nodes in the graph.

Parameters

this	pointer to the ytPGraph instance.

ytPGraph_numParents()

int ytPGraph_numParents	(	const ytPGraph *	this,
		int	j
	)

Returns the number of parents of the specified node.

Parameters

this	pointer to the ytPGraph instance.
j	node index.

Returns

the number of parents of the j -th node.
