Class NodeImpl

java.lang.Object
  com.ibm.di.entry.NodeImpl

All Implemented Interfaces:

Serializable, Node

Direct Known Subclasses:

Attribute, CharacterDataImpl, Property

public abstract class NodeImpl
extends Object
implements Node, Serializable

Basic implementation of the Node interface. Each descendant, except for those that implement the Document interface, should follow the general contract:

• doc = null
  • parent = null -> the Node has neither a parent nor a Document. This might be a brand new Node not yet attached to an Element.
  • parent != null -> the Node has a parent but its parent or the top-most parent is not attached to a Document.
• doc != null
  • parent = null -> this is an Element node attached directly to the Document
  • parent != null -> this is a node which up the hierarchy has a parent attached to a Document

Since:

7.0
