Description copied from class: AbstractLayoutAlgorithm

Apply the layout to the given entities. The entities will be moved and resized based on the algorithm.

Specified by:

applyLayoutInternal in class AbstractLayoutAlgorithm

Parameters:

entitiesToLayout - Apply the algorithm to these entities

relationshipsToConsider - Only consider these relationships when applying the algorithm.

getCurrentLayoutStep

protected int getCurrentLayoutStep()

Description copied from class: AbstractLayoutAlgorithm

Gets the current layout step

Specified by:

getCurrentLayoutStep in class AbstractLayoutAlgorithm

Returns:

getTotalNumberOfLayoutSteps

protected int getTotalNumberOfLayoutSteps()
