Detailed Description

Stores a layout of a graph (coordinates of nodes, bend points of edges).

Constructor & Destructor Documentation

ogdf::Layout::Layout ( )

inline

Creates a layout associated with no graph.

Definition at line 72 of file Layout.h.

ogdf::Layout::Layout ( const Graph &  G )

inline

Creates a layout associated with graph G.

The layout is initialized such that all node positions are (0,0) and all bend point lists of edges are empty.

Parameters:

G	is the corresponding graph .

Member Function Documentation

const DPolyline& ogdf::Layout::bends ( edge  e ) const

inline

Returns the bend point list of edge e.

Definition at line 132 of file Layout.h.

DPolyline& ogdf::Layout::bends ( edge  e )

inline

Returns the bend point list of edge e.

Definition at line 137 of file Layout.h.

void ogdf::Layout::computePolyline	(	GraphCopy &	GC,
		edge	eOrig,
		DPolyline &	dpl
	)		const

Returns the polyline of edge eOrig in dpl.

Parameters:

GC	is the input graph copy; GC must also be the associated graph.
eOrig	is an edge in the original graph of GC.
dpl	is assigned the poyline of eOrig.

void ogdf::Layout::computePolylineClear	(	PlanRep &	PG,
		edge	eOrig,
		DPolyline &	dpl
	)

Returns the polyline of edge eOrig in dpl and clears the bend points of the copies.

The bend point lists of all edges in the edge path corresponding to eOrig are empty afterwards! This is a faster version of computePolyline().

Parameters:

PG	is the input graph copy; PG must also be the associated graph. of this layout.
eOrig	is an edge in the original graph of GC.
dpl	is assigned the poyline of eOrig.
