Class CommonNodeFactory<T extends CommonNode>

java.lang.Object

de.intarsys.tools.tree.CommonNodeFactory<T>

Type Parameters:

T -

public abstract class CommonNodeFactory<T extends CommonNode>
extends Object

The common implementation of a CommonNode factory.

This implementation ensures uniqueness of an object->node association within the parent node. This means within a given parent context, the node returned for a given object is always the same.

While all factories have their own way of creating a node based on the POJO, they all share the ability to "fine tune" the node creation in a certain context (role).

For fine tuning node creation, just register some other node factories using "registerFactory". Upon creation of a node for this specific role, all registered factories are searched if there is a more specific one for the creation based on the objects's class.
