Detailed Description

template<typename Graph>
class lemon::DirPath< Graph >::Builder

This class is used to fill a path with edges.

You can push new edges to the front and to the back of the path in arbitrary order then you should commit these changes to the graph.

Fundamentally, for most "Paths" (classes fulfilling the PathConcept) while the builder is active (after the first modifying operation and until the commit()) the original Path is in a "transitional" state (operations on it have undefined result). But in the case of DirPath the original path remains unchanged until the commit. However we don't recomend that you use this feature.

Constructor & Destructor Documentation

Builder DirPath _P  )  [inline]
 

Parameters:
_P the path you want to fill in.
Definition at line 278 of file path.h.


Member Function Documentation

void setStartNode const GraphNode  )  [inline]
 

Sets the starting node of the path. Edge added to the path afterwards have to be incident to this node. It should be called if and only if the path is empty and before any call to pushFront() or pushBack() Definition at line 287 of file path.h.

References DirPath::GraphNode.

void pushFront const GraphEdge e  )  [inline]
 

Push a new edge to the front of the path.

setStartNode
Definition at line 293 of file path.h.

void pushBack const GraphEdge e  )  [inline]
 

Push a new edge to the back of the path.

void reserveFront size_t  r  )  [inline]
 

If you know a reasonable upper bound of the number of the edges to add to the front, using this function you can speed up the building. Definition at line 324 of file path.h.

void reserveBack size_t  r  )  [inline]
 

If you know a reasonable upper bound of the number of the edges to add to the back, using this function you can speed up the building. Definition at line 331 of file path.h.
