Method Detail

iterator

public java.lang.Iterable<N> iterator(TreeMapModel<N,Row,Column,Color,Font> model,
                                      N root)

Description copied from class: AbstractAlgorithm

Breadth first traversal by default.

Specified by:

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

Overrides:

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

Parameters:

model - the model

root - the root node

Returns:

an iterator to traverse the tree in the specified order

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

isSpaceFilling

public boolean isSpaceFilling()

Specified by:

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

Overrides:

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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
