Method Summary

Modifier and Type	Method and Description
void	close() Closes this input stream and releases any system resources associated with the stream.
ReferenceResolver	getReferenceResolver() Returns the reference resolver that was set for this stream, returns null if no ReferenceResolver has been set.
XMLInputStream	getSubStream() getSubStream() returns a stream which points to the entire next element in the current stream.
boolean	hasNext() Check if there are more events to pull of the stream
XMLEvent	next() Get the next XMLEvent on the stream
XMLEvent	peek() Check the next XMLEvent without reading it from the stream.
void	setReferenceResolver(ReferenceResolver resolver) Provides a way to set the ReferenceResolver of the stream, this is mostly needed for handle references to other parts of the document.
void	skip() Skip the next stream event
boolean	skip(int eventType) Position the stream at the next XMLEvent of this type.
boolean	skip(XMLName name) Position the stream at the next element of this name.
boolean	skip(XMLName name, int eventType) Position the stream at the next element of this name and this type.
void	skipElement() Skips the entire next start tag / end tag pair.

Method Detail

next

XMLEvent next()
       throws XMLStreamException

Get the next XMLEvent on the stream

Throws:

XMLStreamException

See Also:

XMLEvent

hasNext

boolean hasNext()
         throws XMLStreamException

Check if there are more events to pull of the stream

Throws:

XMLStreamException

See Also:

XMLEvent

skip

void skip()
   throws XMLStreamException

Skip the next stream event

Throws:

XMLStreamException

skipElement

void skipElement()
          throws XMLStreamException

Skips the entire next start tag / end tag pair.

Throws:

XMLStreamException

peek

XMLEvent peek()
       throws XMLStreamException

Check the next XMLEvent without reading it from the stream. Returns null if the stream is at EOF or has no more XMLEvents.

Throws:

XMLStreamException

See Also:

XMLEvent

skip

boolean skip(int eventType)
      throws XMLStreamException

Position the stream at the next XMLEvent of this type. The method returns true if the stream contains another XMLEvent of this type and false otherwise.

Parameters:

eventType - An integer code that indicates the element type.

Throws:

XMLStreamException

See Also:

XMLEvent

skip

boolean skip(XMLName name)
      throws XMLStreamException

Position the stream at the next element of this name. The method returns true if the stream contains another element with this name and false otherwise. Skip is a forward operator only. It does not look backward in the stream.

Parameters:

name - An object that defines an XML name. If the XMLName.getNameSpaceName() method on the XMLName argument returns null the XMLName will match just the local name. Prefixes are not checked for equality.

Throws:

XMLStreamException

See Also:

XMLName

skip

boolean skip(XMLName name,
             int eventType)
      throws XMLStreamException

Position the stream at the next element of this name and this type. The method returns true if the stream contains another element with this name of this type and false otherwise.

Parameters:

name - An object that defines an XML name. If the XMLName.getNameSpaceName() method on the XMLName argument returns null the XMLName will match just the local name. Prefixes are not checked for equality.

eventType - An integer code that indicates the element type.

Throws:

XMLStreamException

See Also:

XMLEvent, XMLName

getSubStream

XMLInputStream getSubStream()
                     throws XMLStreamException

getSubStream() returns a stream which points to the entire next element in the current stream. For example: take a document that has a root node A, where the children of A are B, C, and D. If the stream is pointing to the start element of A, getSubStream() will return A, B, C and D including the start element of A and the end element of A. The position of the parent stream is not changed and the events read by the substream are written back to its parent.

Throws:

XMLStreamException

close

void close()
    throws XMLStreamException

Closes this input stream and releases any system resources associated with the stream.

Throws:

XMLStreamException

getReferenceResolver

ReferenceResolver getReferenceResolver()

Returns the reference resolver that was set for this stream, returns null if no ReferenceResolver has been set.

See Also:

ReferenceResolver

setReferenceResolver

void setReferenceResolver(ReferenceResolver resolver)

Provides a way to set the ReferenceResolver of the stream, this is mostly needed for handle references to other parts of the document.
