                                  double height)

Description copied from class: TreeLayoutAlgorithm

Executes this TreeLayoutAlgorithm layout algorithm by referencing the data stored in the repository system. Once done, the result will be saved to the data repository.

Overrides:

preLayoutAlgorithm in class TreeLayoutAlgorithm

Parameters:

entitiesToLayout - Apply the algorithm to these entities

relationshipsToConsider - Only consider these relationships when applying the algorithm.

postLayoutAlgorithm

protected void postLayoutAlgorithm(org.eclipse.zest.layouts.dataStructures.InternalNode[] entitiesToLayout,
                                   org.eclipse.zest.layouts.dataStructures.InternalRelationship[] relationshipsToConsider)

Description copied from class: AbstractLayoutAlgorithm

Code called after the layout algorithm ends

Overrides:

postLayoutAlgorithm in class TreeLayoutAlgorithm

isValidConfiguration

protected boolean isValidConfiguration(boolean asynchronous,
                                       boolean continueous)

Description copied from class: AbstractLayoutAlgorithm

Determines if the configuration is valid for this layout

Overrides:

isValidConfiguration in class TreeLayoutAlgorithm
