All Implemented Interfaces:

Cloneable

public class BeanChildren

extends Children.Keys

Class that represents bean children of a JavaBeans context. It listens on the bean context changes and creates nodes for child beans. By default BeanNodes are created for all child beans, but this behaviour can be changed by providing a different factory to the constructor.

Inner Class Summary

static interface

BeanChildren.Factory Controls which nodes are created for a child bean.

Constructor Summary

BeanChildren(BeanContext bean)
Create BeanNode children based on a Bean context.

BeanChildren(BeanContext bean, BeanChildren.Factory factory)
Create children based on a Bean context.

Constructor Detail

BeanChildren

public BeanChildren(BeanContext bean)

Create BeanNode children based on a Bean context.

Parameters:

bean - the context

BeanChildren

public BeanChildren(BeanContext bean,
                    BeanChildren.Factory factory)

Create children based on a Bean context.

Parameters:

bean - the context

factory - a factory to use for creation of child nodes

Method Detail

createNodes

protected Node[] createNodes(Object subbean)

Creates a node representant for given bean. Uses factory to get the node.

Overrides:

createNodes in class Children.Keys

Parameters:

subbean - the bean from bean context

Returns:

node created by the factory

addNotify

protected void addNotify()

Description copied from class: Children

Called when children are first asked for nodes. Typical implementations at this time calculate their node list (or keys for Children.Keys etc.).

Overrides:

addNotify in class Children

removeNotify

protected void removeNotify()

Removes the listener and does some necessary clean up.
