StaticPath< GR > Class Template Reference

Detailed Description

template<typename GR>
class lemon::StaticPath< GR >

A structure for representing directed path in a digraph.

Template Parameters

GR	The digraph type in which the path is.

In a sense, the path can be treated as a list of arcs. The lemon path type stores just this list. As a consequence it cannot enumerate the nodes in the path and the source node of a zero length path is undefined.

This implementation is completly static, i.e. it can be copy constucted or copy assigned from another path, but otherwise it cannot be modified.

Being the the most memory efficient path type in LEMON, it is intented to be used when you want to store a large number of paths.

Constructor & Destructor Documentation

StaticPath ( )

inline

Default constructor

StaticPath ( const CPath &  cpath )

inline

This path can be initialized from any other path type.

~StaticPath ( )

inline

Destructor of the path

Member Function Documentation

StaticPath& operator= ( const CPath &  cpath )

inline

This path can be made equal to any other path type. It simply makes a copy of the given path.

const Arc& nth ( int  n ) const

inline

Precondition

n is in the [0..length() - 1] range.
