Class ComponentNode<T extends ComponentNode<T>>

java.lang.Object

org.lsst.ccs.description.ComponentNode<T>

Type Parameters:

T - The particular instance of the ComponentNode.

All Implemented Interfaces:

Serializable

public class ComponentNode<T extends ComponentNode<T>>
extends Object
implements Serializable

Abstract class for a node in the concrete implementation of a subsystem description. It is a standard tree node structure containing in addition a key (the name of the component) and the actual component that will be part of the modular structure of the subsystem. Subclasses define how the component is built, by overriding setComponent()
