All Implemented Interfaces:

Direct Known Subclasses:

AbstractTreeNode.Global

Enclosing class:

AbstractTreeNode

public static class AbstractTreeNode.Auto

extends AbstractTreeNode

An AbstractTreeNode that automatically sets the relationship of relations (parent or child) when a connection is created, with the dead relation taking on the relationship of the live one. When a connection is destroyed, the relationship of the relations remains unchanged. As with AbstractTreeNode, the default behavior of making this relation dead (setting relationship null) is to dispose it.

Constructor Detail

AbstractTreeNode.Auto

public AbstractTreeNode.Auto(Relationship relationship)

Creates an instance with an uninitialized delegator. Must call initDelegator() before using this delegate, such as new AbstractTreeNode(r).initDelegator(d).

Parameters:

relationship - This relation's relationship. Null if none (a dead relation).

Method Detail

checkAddChild

protected void checkAddChild(TreeNode childR)

Description copied from class: AbstractTreeNode

Called by the system before adding a child to this parent. The default implementation calls checkRelation() first, checkChild() last, and inbetween it throws an exception if child is null, child is this parent node, child has a parent, or if parent and child are not in the same relationship.

Overrides:

checkAddChild in class AbstractTreeNode

Parameters:

childR - Child relation. Possibly null or duplicate.
