Constructor Detail

CirclemapCompositeNode

public CirclemapCompositeNode(CirclemapNode parent,
                              TreeNode node)

Creates a new instance.

Method Detail

isLeaf

public boolean isLeaf()

Overrides:

isLeaf in class CirclemapNode

children

public java.util.List<CirclemapNode> children()

Overrides:

children in class CirclemapNode

layout

public void layout(NodeInfo info,
                   ProgressObserver p)

Description copied from class: CirclemapNode

Lays out the subtree starting at this data in a space-filling circular treemap.

Overrides:

layout in class CirclemapNode

updateNodeLayout

public void updateNodeLayout(NodeInfo info)

Updates the layout of this node only. Does not update the layout of child nodes or parent nodes.

Parameters:

info -

getDescendantCount

public int getDescendantCount()

Overrides:

getDescendantCount in class CirclemapNode

newChildAdded

public CirclemapNode newChildAdded(TreeNode c)

Call this method when a new child node has been added to the underlying TreeNode.

For performance reasons, this method will not update the layout of the circlemap.

Parameters:

c - the new child

Returns:

Returns the new CirclemapNode which holds the child.
