Detailed Description

This group contains the map structures implemented in LEMON.

LEMON provides several special purpose maps and map adaptors that e.g. combine new maps from existing ones.

class	ConstMap< K, Const< V, v > >
	Constant map with inlined constant value. More...

class	IdentityMap< T >
	Identity map. More...

class	RangeMap< V >
	Map for storing values for integer keys from the range `[0..size-1]`. More...

NullMap< K, V > nullMap ( )

ConstMap< K, V > constMap ( const V & v )

ConstMap< K, Const< V, v > > constMap ( )

IdentityMap< T > identityMap ( )

RangeMap< V > rangeMap	(	int	size = `0`,
		const V &	value = `V()`
	)

RangeMap< V > rangeMap ( const std::vector< V > & vector )

SparseMap< K, V, Compare > sparseMap ( const V & value = V() )

SparseMap< K, V, Compare > return SparseMap< K, V, Compare >	(	map	,
		value
	)

TrueMap< K > trueMap ( )

FalseMap< K > falseMap ( )

LoggerBoolMap< Iterator > loggerBoolMap ( Iterator it )

The most important usage of it is storing certain nodes or arcs that were marked true by an algorithm. For example, it makes easier to store the nodes in the processing order of Dfs algorithm, as the following examples show.

*    std::vector<Node> v;
*    dfs(g).processedMap(loggerBoolMap(std::back_inserter(v))).run(s);
*  

*    std::vector<Node> v(countNodes(g));
*    dfs(g).processedMap(loggerBoolMap(v.begin())).run(s);
*  

Note: The container of the iterator must contain enough space for the elements or the iterator should be an inserter iterator.; LoggerBoolMap is just writable, so it cannot be used when a readable map is needed, for example, as ReachedMap for Bfs, Dfs and Dijkstra algorithms.
