Member Function Documentation

call()

virtual void ogdf::LayoutPlanRepModule::call ( PlanRep &  PG, adjEntry  adjExternal, Layout &  drawing  )

pure virtual

Computes a planar layout of PG in drawing.

Must be overridden by derived classes. The implementation must also set m_boundingBox, which gives the bounding box of the computed layout.

Parameters

PG	is the input planarized representation which may be modified.
adjExternal	is an adjacenty entry on the external face.
drawing	is the computed layout of PG.

Implemented in ogdf::OrthoLayout.

getBoundingBox()

const DPoint & ogdf::LayoutPlanRepModule::getBoundingBox ( ) const

inline

Returns the bounding box of the computed layout.

Definition at line 73 of file LayoutPlanRepModule.h.

operator()()

void ogdf::LayoutPlanRepModule::operator() ( PlanRep &  PG, adjEntry  adjExternal, Layout &  drawing  )

inline

Computes a planar layout of PG in drawing.

Definition at line 68 of file LayoutPlanRepModule.h.

separation() [1/2]

virtual double ogdf::LayoutPlanRepModule::separation ( ) const

pure virtual

Returns the minimal allowed distance between edges and vertices.

Implemented in ogdf::OrthoLayout.

separation() [2/2]

virtual void ogdf::LayoutPlanRepModule::separation ( double  sep )

pure virtual

Sets the minimal allowed distance between edges and vertices to sep.

Implemented in ogdf::OrthoLayout.

setBoundingBox()

void ogdf::LayoutPlanRepModule::setBoundingBox ( PlanRep &  PG, Layout &  drawing  )

inlineprotected

Computes and sets the bounding box variable m_boundingBox.

An algorithm can call setBoundingBox() for setting the m_boundingBox variable if no faster implementation is available.

Definition at line 93 of file LayoutPlanRepModule.h.

Member Data Documentation

m_boundingBox

DPoint ogdf::LayoutPlanRepModule::m_boundingBox

protected

Stores the bounding box of the computed layout.

Must be set by derived algorithms!
