Detailed Description

FullBpGraph is a simple and fast implmenetation of undirected full bipartite graphs. It contains an edge between every red-blue pairs of nodes, therefore the number of edges is nr*nb. This class is completely static and it needs constant memory space. Thus you can neither add nor delete nodes or edges, however the structure can be resized using resize().

This type fully conforms to the BpGraph concept. Most of its member functions and nested classes are documented only in the concept class.

This class provides constant time counting for nodes, edges and arcs.

Constructor & Destructor Documentation

FullBpGraph ( )

inline

Default constructor. The number of nodes and edges will be zero.

FullBpGraph	(	int	redNum,
		int	blueNum
	)

inline

Constructor.

Parameters

redNum	The number of the red nodes.
blueNum	The number of the blue nodes.

Member Function Documentation

void resize	(	int	redNum,
		int	blueNum
	)

inline

This function resizes the graph. It fully destroys and rebuilds the structure, therefore the maps of the graph will be reallocated automatically and the previous values will be lost.

RedNode redNode ( int index ) const

inline

Returns the red node with the given index. Since this structure is completely static, the red nodes can be indexed with integers from the range [0..redNum()-1].

See Also: redIndex()

int index ( RedNode node ) const

inline

Returns the index of the given red node. Since this structure is completely static, the red nodes can be indexed with integers from the range [0..redNum()-1].

See Also: operator()()

BlueNode blueNode ( int index ) const

inline

Returns the blue node with the given index. Since this structure is completely static, the blue nodes can be indexed with integers from the range [0..blueNum()-1].

See Also: blueIndex()

int index ( BlueNode node ) const

inline

Returns the index of the given blue node. Since this structure is completely static, the blue nodes can be indexed with integers from the range [0..blueNum()-1].

See Also: operator()()

Edge edge	(	const Node &	u,
		const Node &	v
	)		const

inline

Returns the edge which connects the given nodes.

Arc arc	(	const Node &	u,
		const Node &	v
	)		const

inline

Returns the arc which connects the given nodes.
