Log:
WSCOMMONS-487: Implemented a new extension mechanism to retrieve DataHandler
objects from an XMLStreamReader implementation. This supersedes the existing
IS_DATA_HANDLERS_AWARE extension, but compatibility is maintained (tested with
Axis2).

conform to the following

+ * property identified by {...@link
org.apache.axiom.om.OMConstants#IS_DATA_HANDLERS_AWARE},

and its value must not
+ * change during the lifetime of the {...@link XMLStreamReader}
implementation.</li>
+ * <li>
+ * <p>
+ * If the {...@link XMLStreamReader} wishes to expose base64 encoded content
using a
+ * {...@link javax.activation.DataHandler} object, it must do so using a single
+ * {...@link XMLStreamConstants#CHARACTERS} event.
+ * </p>
+ * <p>
+ * To maintain compatibility with consumers that are unaware of the extensions
described here, the
+ * implementation should make sure that {...@link XMLStreamReader#getText()},
+ * {...@link XMLStreamReader#getTextStart()}, {...@link
XMLStreamReader#getTextLength()},
+ * {...@link XMLStreamReader#getTextCharacters()},
+ * {...@link XMLStreamReader#getTextCharacters(int, char[], int, int)} and
+ * {...@link XMLStreamReader#getElementText()} behave as expected for this
type of event, i.e. return
+ * the base64 representation of the binary content.
+ * </p>
+ * </li>
+ * <li>{...@link XMLStreamReader#getProperty(String)} must return {...@link
Boolean#TRUE} for the
+ * property identified by {...@link org.apache.axiom.om.OMConstants#IS_BINARY}
if the current event is
+ * a {...@link XMLStreamConstants#CHARACTERS} event representing base64
encoded binary content and for
+ * which a {...@link javax.activation.DataHandler} is available. For all other
events, the returned
+ * value must be {...@link Boolean#FALSE}.</li>
+ * <li>
+ * <p>
+ * If for a given event, the implementation returned {...@link Boolean#TRUE}
for the
+ * {...@link org.apache.axiom.om.OMConstants#IS_BINARY} property, then a call
to
+ * {...@link XMLStreamReader#getProperty(String)} with argument
+ * {...@link org.apache.axiom.om.OMConstants#DATA_HANDLER} must return the
corresponding
+ * {...@link javax.activation.DataHandler} object.
+ * </p>
+ * <p>
+ * The {...@link org.apache.axiom.om.OMConstants#DATA_HANDLER} property is
undefined for any other type
+ * of event. This implies that the consumer of the {...@link XMLStreamReader}
must check the
+ * {...@link org.apache.axiom.om.OMConstants#IS_BINARY} property before
retrieving the

/**
* StAX based builder that produces a pure XML infoset compliant object model.
- *
- * <h3>XMLStreamReader extensions for optimized base64 handling</h3>
- *
- * <p>This class supports {...@link XMLStreamReader} instances that expose
base64 encoded binary
- * content as {...@link javax.activation.DataHandler} objects. For this to
work, the
- * {...@link XMLStreamReader} must conform to the following requirements:</p>
- * <ol>
- * <li>{...@link XMLStreamReader#getProperty(String)} must return {...@link
Boolean#TRUE}
- * for the property identified by
- * {...@link org.apache.axiom.om.OMConstants#IS_DATA_HANDLERS_AWARE},
regardless of
- * the current event. The property is assumed to be immutable and its
value must
- * not change during the lifetime of the {...@link XMLStreamReader}
implementation.</li>
- * <li><p>If the {...@link XMLStreamReader} wishes to expose base64 encoded
content using
- * a {...@link javax.activation.DataHandler} object, it must do so using
a single
- * {...@link XMLStreamConstants#CHARACTERS} event.</p>
- * <p>To maintain compatibility with consumers that are unaware of the
extensions
- * described here, the implementation should make sure that
- * {...@link XMLStreamReader#getText()}, {...@link
XMLStreamReader#getTextStart()},
- * {...@link XMLStreamReader#getTextLength()}, {...@link
XMLStreamReader#getTextCharacters()},
- * {...@link XMLStreamReader#getTextCharacters(int, char[], int, int)}
and
- * {...@link XMLStreamReader#getElementText()} behave as expected for
this type of event,
- * i.e. return the base64 representation of the binary content.</p></li>
- * <li>{...@link XMLStreamReader#getProperty(String)} must return {...@link
Boolean#TRUE}
- * for the property identified by
- * {...@link org.apache.axiom.om.OMConstants#IS_BINARY} if the current
event is a
- * {...@link XMLStreamConstants#CHARACTERS} event representing base64
encoded binary
- * content and for which a {...@link javax.activation.DataHandler} is
available.
- * For all other events, the returned value must be {...@link
Boolean#FALSE}.</li>
- * <li><p>If for a given event, the implementation returned {...@link
Boolean#TRUE} for the
- * {...@link org.apache.axiom.om.OMConstants#IS_BINARY} property, then a
call to
- * {...@link XMLStreamReader#getProperty(String)} with argument
- * {...@link org.apache.axiom.om.OMConstants#DATA_HANDLER} must return
the
- * corresponding {...@link javax.activation.DataHandler} object.</p>
- * <p>The {...@link org.apache.axiom.om.OMConstants#DATA_HANDLER}
property is undefined
- * for any other type of event. This implies that the consumer of the
- * {...@link XMLStreamReader} must check the {...@link
org.apache.axiom.om.OMConstants#IS_BINARY}
- * property before retrieving the {...@link
org.apache.axiom.om.OMConstants#DATA_HANDLER}
- * property.</p></li>
- * </ol>
- * <p>The extension described will typically be implemented by {...@link
XMLStreamReader} instances
- * provided by databinding frameworks or {...@link XMLStreamReader} proxies
that enrich a stream of
- * StAX events with binary data existing outside of the XML document. Another
example is
- * {...@link org.apache.axiom.om.impl.OMStAXWrapper}.</p>
- * <p>One may ask why this extension is defined using {...@link
XMLStreamReader} properties and not
- * simply as an extension interface that the reader may implement. The reason
is that the property
- * based approach continues to work if the {...@link XMLStreamReader}
implementing the extension
- * is accessed through a proxy implementing the {...@link XMLStreamReader}
interface but unaware
- * of the extension, at least if the proxy correctly delegates calls to the
- * {...@link XMLStreamReader#getProperty(String)} method.</p>
+ * <p>
+ * This class supports the {...@link XMLStreamReader} extension defined by
+ * {...@link org.apache.axiom.stax.ext.DataHandlerReader} as well as the
legacy extension mechanism
+ * defined in the documentation of {...@link DataHandlerReaderUtil}.
