Method Details

getProperties

public MutableProperties getProperties()

Description copied from interface: Algorithm

Properties for storing layout algorithm specific options.

Specified by:

getProperties in interface Algorithm

Overrides:

getProperties in class AbstractAlgorithm

Returns:

the specific properties of this algorithm

breadthFirstLayout

public boolean breadthFirstLayout(com.macrofocus.geom.Shape shape,
 MutableTreeMapNode parent,
 MutableTreeMapNode[] children,
 double sumSizes,
 int horizontalVanishingPoint,

 TreeMapWorker worker)

Description copied from interface: Algorithm

Arrange the items in the given array to fill the given shape. This is called during the first pass, while traversing the tree top down.

Specified by:

Parameters:

shape - the current rectangle being divided.

parent - the parent node.

children - the items to map.

sumSizes - the size of the parent.

horizontalVanishingPoint -

verticalVanishingPoint -

worker - the worker thread

Returns:

true if the layout has been cancelled, false otherwise
