public LiveTreeNode()

Method Detail

getChild

public TreeNode getChild(int index)

Description copied from interface: TreeNode

Get the child at the specified index.

Specified by:

getChild in interface TreeNode

getChildren

public Iterator getChildren()

Description copied from interface: TreeNode

Get an Iterator for the children.

Specified by:

getChildren in interface TreeNode

getChildCount

public int getChildCount()

Description copied from interface: TreeNode

Get the number of children that this object has.

Specified by:

getChildCount in interface TreeNode

getParent

public TreeNode getParent()

Description copied from interface: TreeNode

Get the parent of this object.

Specified by:

getParent in interface TreeNode

setParent

public void setParent(TreeNode p)

Description copied from interface: MutableTreeNode

Set the parent of this TreeNode.

Specified by:

setParent in interface MutableTreeNode

removeChild

public void removeChild(MutableTreeNode ch)

Description copied from interface: MutableTreeNode

Remove a child from this TreeNode.

Specified by:

removeChild in interface MutableTreeNode

addChild

public void addChild(MutableTreeNode ch)

Description copied from interface: MutableTreeNode

Add a child to this TreeNode at the end of the child list. If the child is already in the child list it will be removed and then added to the end.

Specified by:
