public class DeferredElementImpl

extends ElementImpl

implements DeferredNode

Elements represent most of the "markup" and structure of the document. They contain both the data for the element itself (element name and attributes), and any contained nodes, including document text (as children).

Elements may have Attributes associated with them; the API for this is defined in Node, but the function is implemented here. In general, XML applications should retrive Attributes as Nodes, since they may contain entity references and hence be a fairly complex sub-tree. HTML users will be dealing with simple string values, and convenience methods are provided to work in terms of Strings.

Field Detail

fNodeIndex

protected transient int fNodeIndex

Node index.

Method Detail

getNodeIndex

public final int getNodeIndex()

Returns the node index.

Specified by:

getNodeIndex in interface DeferredNode

synchronizeData

protected final void synchronizeData()

Synchronizes the data (name and value) for fast nodes.

Overrides:

synchronizeData in class ElementImpl

synchronizeChildren

protected final void synchronizeChildren()

Synchronizes the node's children with the internal structure. Fluffing the children at once solves a lot of work to keep the two structures in sync. The problem gets worse when editing the tree -- this makes it a lot easier.

Overrides:

synchronizeChildren in class NodeImpl
