Class WrappedTextNodeStreamReader

java.lang.Object
  extended by org.apache.axiom.util.stax.WrappedTextNodeStreamReader
All Implemented Interfaces:
XMLStreamConstants, XMLStreamReader

public class WrappedTextNodeStreamReader
extends Object
implements XMLStreamReader

XMLStreamReader implementation that represents a text node wrapped inside an element. The text data is provided by a Reader.

It will produce the following sequence of XML events:

The class is implemented as a simple state machine, where the state is identified by the current event type. The initial state is START_DOCUMENT and the following transitions are triggered by next(): Additionally, getElementText() triggers the following transition: Note that since multiple consecutive CHARACTERS events may be returned, this "parser" is not coalescing.
