Method Detail

setParent

public void setParent(XMLEventReader reader)

Sets the parent.

getParent

public XMLEventReader getParent()

Returns the parent.

nextEvent

public XMLEvent nextEvent()
                   throws XMLStreamException

Description copied from interface: XMLEventReader

Returns the next XML event.

Specified by:

nextEvent in interface XMLEventReader

Throws:

XMLStreamException

next

public Object next()

Description copied from interface: Iterator

Obtain the next element in the collection.

Specified by:

next in interface Iterator

Returns:

the next element in the collection

hasNext

public boolean hasNext()

Description copied from interface: XMLEventReader

Indicates whether there are more XML events to be read.

Specified by:

hasNext in interface Iterator

Specified by:

hasNext in interface XMLEventReader

Returns:

true if there is at least one more element in the collection

peek

public XMLEvent peek()
              throws XMLStreamException

Description copied from interface: XMLEventReader

Looks at the next XML event without advancing the cursor in the stream. Returns null if there are no more events to read.

Specified by:

peek in interface XMLEventReader

Throws:

XMLStreamException

getElementText

public String getElementText()
                      throws XMLStreamException

Description copied from interface: XMLEventReader

Reads the text context of an element. When invoked, the current event must be START_ELEMENT. On completion, the current event will be END_ELEMENT.

Specified by:

getElementText in interface XMLEventReader

Throws:

XMLStreamException

nextTag

public XMLEvent nextTag()
                 throws XMLStreamException

Description copied from interface: XMLEventReader

Returns the next element event. This method skips insignificant space until a START_ELEMENT or END_ELEMENT event is found.

Specified by:

nextTag in interface XMLEventReader

Throws:

XMLStreamException - if an event that was not an insignificant space event was encountered

getProperty

public Object getProperty(String name)
                   throws IllegalArgumentException

Returns the implementation-specific feature or property of the given name.

Specified by:

getProperty in interface XMLEventReader

Throws:

IllegalArgumentException - if the property is not supported

close

public void close()
           throws XMLStreamException

Description copied from interface: XMLEventReader

Free any resources associated with this parser. This method will not close the underlying input source.

Specified by:

close in interface XMLEventReader

Throws:

XMLStreamException

remove

public void remove()

Description copied from interface: Iterator

Remove from the underlying collection the last element returned by next (optional operation). This method can be called only once after each call to next(). It does not affect what will be returned by subsequent calls to next.
