Class EventReaderDelegate

  • All Implemented Interfaces:
    Iterator, XMLEventReader


    public class EventReaderDelegate
    extends Object
    implements XMLEventReader
    This is the base class for deriving an XMLEventReader filter. This class is designed to sit between an XMLEventReader and an application's XMLEventReader. By default each method does nothing but call the corresponding method on the parent interface.
    Since:
    1.6
    Version:
    1.0
    See Also:
    XMLEventReader, StreamReaderDelegate
    • Constructor Detail

      • EventReaderDelegate

        public EventReaderDelegate()
        Construct an empty filter with no parent.
      • EventReaderDelegate

        public EventReaderDelegate(XMLEventReader reader)
        Construct an filter with the specified parent.
        Parameters:
        reader - the parent
    • Method Detail

      • setParent

        public void setParent(XMLEventReader reader)
        Set the parent of this instance.
        Parameters:
        reader - the new parent
      • getParent

        public XMLEventReader getParent()
        Get the parent of this instance.
        Returns:
        the parent or null if none is set
      • next

        public Object next()
        Description copied from interface: Iterator
        Returns the next element in the iteration.
        Specified by:
        next in interface Iterator
        Returns:
        the next element in the iteration
      • hasNext

        public boolean hasNext()
        Description copied from interface: 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
      • getElementText

        public String getElementText()
                              throws XMLStreamException
        Description copied from interface: 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: 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
      • remove

        public void remove()
        Description copied from interface: Iterator
        Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to Iterator.next(). The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.
        Specified by:
        remove in interface Iterator
