All Implemented Interfaces:

Delegatable, Disposable, Relation, java.io.Serializable, TreeNode

Enclosing class:

AbstractTreeNode

public static class AbstractTreeNode.Global

extends AbstractTreeNode.Auto

An AbstractTreeNode.Auto that uses a singleton (global) relationship, and throws an exception if the relationship is changed. This allows a client to use tree nodes without bothering to set the relationship, but it also means that the global relationship reports events for all relations in the global relationship.

Constructor Detail

AbstractTreeNode.Global

public AbstractTreeNode.Global()

Creates an instance with an uninitialized delegator and TreeNodes.GlobalTree as the relationship. Must call initDelegator() before using this delegate, such as new Global().initDelegator(d).

AbstractTreeNode.Global

public AbstractTreeNode.Global(Relationship relationship)

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

Parameters:

relationship - This relation's singleton relationship. Never null. If not a singleton this class will not work as expected.

Method Detail

setRelationship

public void setRelationship(Relationship relationship)

Description copied from interface: Relation

Sets the relationship that this relation belongs to. If this relation is going dead implementors must satisfy the relation contract by actively disconnecting it from all relations, or passively throwing an exception. Unless otherwise noted, no change in relationship is ignored.

Specified by:

setRelationship in interface Relation

Overrides:

setRelationship in class AbstractRelation

Parameters:

relationship - The relationship. Null if none (dead).

Throws:

java.lang.UnsupportedOperationException - This relation's relationship is immutable.
