Constructor Details

XMLEventReaderBase

public XMLEventReaderBase(XMLStreamReader reader)
                   throws XMLStreamException

Throws:

XMLStreamException

XMLEventReaderBase

public XMLEventReaderBase(XMLStreamReader reader,
 XMLEventAllocator alloc)
                   throws XMLStreamException

Throws:

XMLStreamException

Method Details

setAllocator

public void setAllocator(XMLEventAllocator allocator)

getElementText

public String getElementText()
                      throws XMLStreamException

Description copied from interface: javax.xml.stream.XMLEventReader

Reads the content of a text-only element. Precondition: the current event is START_ELEMENT. Postcondition: The current event is the corresponding END_ELEMENT.

Specified by:

getElementText in interface XMLEventReader

Throws:

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

nextTag

public XMLEvent nextTag()
                 throws XMLStreamException

Description copied from interface: javax.xml.stream.XMLEventReader

Skips any insignificant space events until a START_ELEMENT or END_ELEMENT is reached. If anything other than space characters are encountered, an exception is thrown. This method should be used when processing element-only content because the parser is not able to recognize ignorable whitespace if the DTD is missing or not interpreted.

Specified by:

nextTag in interface XMLEventReader

Throws:

XMLStreamException - if anything other than space characters are encountered

next

public Object next()

Specified by:

next in interface Iterator

nextEvent

public XMLEvent nextEvent()
                   throws XMLStreamException

Description copied from interface: javax.xml.stream.XMLEventReader

Get the next XMLEvent

Specified by:

nextEvent in interface XMLEventReader

Throws:

XMLStreamException

See Also:

• XMLEvent

hasNext

public boolean hasNext()

Description copied from interface: javax.xml.stream.XMLEventReader

Check if there are more events. Returns true if there are more events and false otherwise.

Specified by:

hasNext in interface Iterator

Specified by:

hasNext in interface XMLEventReader

Returns:

true if the event reader has more events, false otherwise

peek

public XMLEvent peek()
              throws XMLStreamException

Description copied from interface: javax.xml.stream.XMLEventReader

Check the next XMLEvent without reading it from the stream. Returns null if the stream is at EOF or has no more XMLEvents. A call to peek() will be equal to the next return of next().

Specified by:

peek in interface XMLEventReader

Throws:

XMLStreamException

See Also:

• XMLEvent

add

public void add(XMLEvent event)
         throws XMLStreamException

Description copied from interface: javax.xml.stream.util.XMLEventConsumer

This method adds an event to the consumer. Calling this method invalidates the event parameter. The client application should discard all references to this event upon calling add. The behavior of an application that continues to use such references is undefined.

Specified by:

add in interface XMLEventConsumer

Parameters:

event - the event to add, may not be null

Throws:

XMLStreamException

needsMore

protected boolean needsMore()

get

protected XMLEvent get()
                throws XMLStreamException

Throws:

XMLStreamException

isOpen

protected boolean isOpen()

internal_close

protected void internal_close()

close

public void close()
           throws XMLStreamException

Description copied from interface: javax.xml.stream.XMLEventReader

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

Specified by:

close in interface XMLEventReader

Throws:

XMLStreamException - if there are errors freeing associated resources

parseSome

protected boolean parseSome()
                     throws XMLStreamException

Throws:

XMLStreamException

setConfigurationContext

public void setConfigurationContext(ConfigurationContextBase base)

getProperty

public Object getProperty(String name)

Description copied from interface: javax.xml.stream.XMLEventReader

Get the value of a feature/property from the underlying implementation

Specified by:

getProperty in interface XMLEventReader

Parameters:

name - The name of the property

Returns:

The value of the property

remove

public void remove()

Specified by:

remove in interface Iterator

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception
