Member Function Documentation

call()

void ogdf::HierarchyLayoutModule::call ( const HierarchyLevelsBase &  levels, GraphAttributes &  GA  )

inline

Computes a hierarchy layout of levels in GA.

Parameters

levels	is the input hierarchy.
GA	is assigned the hierarchy layout.

Definition at line 59 of file HierarchyLayoutModule.h.

doCall()

virtual void ogdf::HierarchyLayoutModule::doCall ( const HierarchyLevelsBase &  levels, GraphAttributes &  AGC  )

protectedpure virtual

Implements the actual algorithm call.

Must be implemented by derived classes.

Parameters

levels	is the input hierarchy.
AGC	has to be assigned the hierarchy layout.

Implemented in ogdf::FastHierarchyLayout, ogdf::FastSimpleHierarchyLayout, and ogdf::OptimalHierarchyLayout.
