Method Detail

clone

public java.lang.Object clone()

Creates a new node with the same user object, label, and description. The children and parent nodes are not included in the new node.

Overrides:

clone in class javax.swing.tree.DefaultMutableTreeNode

Returns:

a new node as a copy of this one

Specified by:

getFilterLabel in interface FilterLogicBaseNodeInterface

getFilterDescription

public java.lang.String getFilterDescription()

Description copied from interface: FilterLogicBaseNodeInterface

Returns the description for this node

Specified by:

getFilterDescription in interface FilterLogicBaseNodeInterface

getMaxChildren

public int getMaxChildren()

Description copied from interface: FilterLogicBaseNodeInterface

Return the maximum number of child nodes allowed -1 = unlimited 0 = none

Specified by:

getMaxChildren in interface FilterLogicBaseNodeInterface

Returns:

int (number allowed)

getChildLogicNodeAt

public FilterLogicBaseNodeInterface getChildLogicNodeAt(int childIndex)

Description copied from interface: FilterLogicBaseNodeInterface

Returns the child node at a specific index

Specified by:

getChildLogicNodeAt in interface FilterLogicBaseNodeInterface

Returns:

Sets the label for this node.

Parameters:

string - the new label

setUserObject

public void setUserObject(java.lang.Object userObject)

Specified by:

setUserObject in interface javax.swing.tree.MutableTreeNode

Overrides:

setUserObject in class javax.swing.tree.DefaultMutableTreeNode

getIndex

public int getIndex(javax.swing.tree.TreeNode aChild)

Returns the index of the specified child in this node's child array. If the specified node is not a child of this node, returns -1. This method performs a linear search and is O(n) where n is the number of children.

Specified by:

getIndex in interface javax.swing.tree.TreeNode

Overrides:

getIndex in class javax.swing.tree.DefaultMutableTreeNode

Parameters:

aChild - the TreeNode to search for among this node's children
