◆ buildOneLevel()

bool ogdf::EdgeCoverMerger::buildOneLevel ( MultilevelGraph MLG)

This method constructs one more level on top of an existing MultilevelGraph.

It must be implemented in any MultilevelBuilder. A level is built by adding node-merges to the MultilevelGraph and updating the graph accordingly. This is achieved by calling MLG.

MLGis the MultilevelGraph for which a new gevel will be built.
true if the Graph was changed or false if no level can be built.

Implements ogdf::MultilevelBuilder.
