Constructor Details

EventReaderDelegate

public EventReaderDelegate()
Constructs an empty filter with no parent set.

EventReaderDelegate

public EventReaderDelegate(XMLEventReader reader)
Constructs an empty filter with the given parent.

Method Details

close

public void close()
            throws XMLStreamException
Free any resources associated with this parser. This method will not close the underlying input source.
Specified by:
close in interface XMLEventReader

getElementText

public String getElementText()
            throws XMLStreamException
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

getParent

public XMLEventReader getParent()
Returns the parent.

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

hasNext

public boolean hasNext()
Indicates whether there are more XML events to be read.
Specified by:
hasNext in interface XMLEventReader
hasNext in interface Iterator<E>

next

public Object next()
Obtain the next element in the collection.
Specified by:
next in interface Iterator<E>
Returns:
the next element in the collection
Throws:
NoSuchElementException - if there are no more elements

nextEvent

public XMLEvent nextEvent()
            throws XMLStreamException
Returns the next XML event.
Specified by:
nextEvent in interface XMLEventReader

nextTag

public XMLEvent nextTag()
            throws XMLStreamException
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

peek

public XMLEvent peek()
            throws XMLStreamException
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

remove

public void remove()
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.
Specified by:
remove in interface Iterator<E>
Throws:
IllegalStateException - if next has not yet been called or remove has already been called since the last call to next.
UnsupportedOperationException - if this Iterator does not support the remove operation.

setParent

public void setParent(XMLEventReader reader)
Sets the parent.
