startLayout
public void startLayout(java.awt.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 interfaceAlgorithm<N,Row,Column,Color,Font>
- Overrides:
startLayout
in classAbstractAlgorithm<N,Row,Column,Color,Font>
- Parameters:
bounds
- the bounds of the viewmodel
- the modelroot
- the root node
-
breadthFirstLayout
public boolean breadthFirstLayout(java.awt.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.worker
- the worker thread- Returns:
- true if the layout has been cancelled, false otherwise
-
isCompatible
public boolean isCompatible(java.awt.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
