public Class MappedXMLStreamReader

Implements javax.xml.stream.XMLStreamReader.close.

Doc from javax.xml.stream.XMLStreamReader.close.

Frees any resources associated with this Reader. This method does not close the underlying input source.

Exceptions

XMLStreamException:

if there are errors freeing associated resources

Implements javax.xml.stream.XMLStreamReader.getElementText.

Doc from javax.xml.stream.XMLStreamReader.getElementText.

Reads the content of a text-only element, an exception is thrown if this is not a text-only element. Regardless of value of javax.xml.stream.isCoalescing this method always returns coalesced content.
Precondition: the current event is START_ELEMENT.
Postcondition: the current event is the corresponding END_ELEMENT.
The method does the following (implementations are free to optimized but must do equivalent processing):

if(getEventType() != XMLStreamConstants.START_ELEMENT) {
    throw new XMLStreamException(
    "parser must be on START_ELEMENT to read next text", getLocation());
}

int eventType = next();
StringBuffer content = new StringBuffer();
while(eventType != XMLStreamConstants.END_ELEMENT) {
    if(eventType == XMLStreamConstants.CHARACTERS
       || eventType == XMLStreamConstants.CDATA
       || eventType == XMLStreamConstants.SPACE
       || eventType == XMLStreamConstants.ENTITY_REFERENCE) {
          buf.append(getText());
    } else if(eventType == XMLStreamConstants.PROCESSING_INSTRUCTION
              || eventType == XMLStreamConstants.COMMENT) {
        // skipping
    } else if(eventType == XMLStreamConstants.END_DOCUMENT) {
        throw new XMLStreamException(
        "unexpected end of document when reading element text content", this);
    } else if(eventType == XMLStreamConstants.START_ELEMENT) {
        throw new XMLStreamException(
        "element text content may not contain START_ELEMENT", getLocation());
    } else {
        throw new XMLStreamException(
        "Unexpected event type "+eventType, getLocation());
    }
    eventType = next();
}
return buf.toString();

Returns:String

the content of a text-only element

Exceptions

XMLStreamException:

if the current event is not a START_ELEMENT or if a non text element is encountered

Implements javax.xml.stream.XMLStreamReader.getNamespaceContext.

Doc from javax.xml.stream.XMLStreamReader.getNamespaceContext.

Returns a read only namespace context for the current position. The context is transient and only valid until a call to next() changes the state of the reader.

Returns:NamespaceContext

return a namespace context

Implements javax.xml.stream.XMLStreamReader.getText.

Doc from javax.xml.stream.XMLStreamReader.getText.

Returns the current value of the parse event as a string, this returns the string value of a CHARACTERS event, returns the value of a COMMENT, the replacement value for an ENTITY_REFERENCE, the string value of a CDATA section, the string value for a SPACE event, or the String value of the internal subset of the DTD. If an ENTITY_REFERENCE has been resolved, any character data will be reported as CHARACTERS events.

Returns:String

the current text or null

Implements javax.xml.stream.XMLStreamReader.next.

Doc from javax.xml.stream.XMLStreamReader.next.

Get next parsing event - a processor may return all contiguous character data in a single chunk, or it may split it into several chunks. If the property javax.xml.stream.isCoalescing is set to true element content must be coalesced and only one CHARACTERS event must be returned for contiguous element content or CDATA Sections. By default entity references must be expanded and reported transparently to the application. An exception will be thrown if an entity reference cannot be expanded. If element content is empty (i.e. content is "") then no CHARACTERS event will be reported.

Given the following XML:
<foo><!--description-->content text<![CDATA[<greeting>Hello>/greeting>]]>other content>/foo>
The behavior of calling next() when being on foo will be:
1- the comment (COMMENT)
2- then the characters section (CHARACTERS)
3- then the CDATA section (another CHARACTERS)
4- then the next characters section (another CHARACTERS)
5- then the END_ELEMENT

Returns:int

the integer code corresponding to the current parse event

Exceptions

XMLStreamException:

if there is an error processing the underlying XML source
