Class DOMStreamReader

java.lang.Object
  com.sun.xml.ws.streaming.DOMStreamReader

All Implemented Interfaces:: javax.xml.namespace.NamespaceContext, javax.xml.stream.XMLStreamConstants, javax.xml.stream.XMLStreamReader

public class DOMStreamReader
extends java.lang.Object
implements javax.xml.stream.XMLStreamReader, javax.xml.namespace.NamespaceContext
extends java.lang.Object
implements javax.xml.stream.XMLStreamReader, javax.xml.namespace.NamespaceContext

Create an XMLStreamReader on top of a DOM tree.

Since various libraries as well as users often create "incorrect" DOM node, this class spends a lot of efforts making sure that broken DOM trees are nevertheless interpreted correctly.

For example, if a DOM level 1 tree is passed, each method will attempt to return the correct value by using Node.getNodeName().

Similarly, if DOM is missing explicit namespace declarations, this class attempts to emulate necessary declarations.

Nested Class Summary
`protected static class`	`DOMStreamReader.Scope` Namespace declarations on one element.

Field Summary
`protected org.w3c.dom.Node`	`_current` Current DOM node being traversed.
`protected int`	`_state` State of this reader.
`protected int`	`depth` Depth of the current element.
`protected DOMStreamReader.Scope[]`	`scopes` `DOMStreamReader.Scope` buffer.
`protected java.lang.String`	`wholeText` If the reader points at `the text node`, its whole value.

Field Detail

_current

protected org.w3c.dom.Node _current

Current DOM node being traversed.

wholeText

protected java.lang.String wholeText

If the reader points at the text node, its whole value.

This is simply a cache of Text.getWholeText() of _current, but when a large binary data sent as base64 text, this could get very much non-trivial.

scopes

protected DOMStreamReader.Scope[] scopes

DOMStreamReader.Scope buffer.

depth

protected int depth

Depth of the current element. The first element gets depth==0. Also used as the index to scopes.

_state

protected int _state

State of this reader. Any of the valid states defined in StAX' XMLStreamConstants class.
