Method Details

startLayout

public void startLayout(com.macrofocus.geom.Rectangle2D bounds,
 TreeMapModel<N,Row,Column,Color,Font> model,
 N root,
 TreeMapWorker worker)

Description copied from class: AbstractAlgorithm

Do nothing by default.

Specified by:

startLayout in interface Algorithm<N,Row,Column,Color,Font>

Overrides:

startLayout in class AbstractAlgorithm<N,Row,Column,Color,Font>

Parameters:

bounds - the bounds of the view

model - the model

root - the root node

worker -

breadthFirstLayout

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

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

isCompatible

public boolean isCompatible(com.macrofocus.geom.Shape shape)

Description copied from interface: Algorithm

Indicates whether the layout algorithm can handle the given geometry of its parent

Parameters:

shape - the geometry of its parent

Returns:

true if it can lay out the children using the specified geometrical shape
