Class EventReaderDelegate
java.lang.Object
javax.xml.stream.util.EventReaderDelegate
- All Implemented Interfaces:
- Iterator<Object>,- 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

Constructor Details- 
EventReaderDelegatepublic EventReaderDelegate()Construct an empty filter with no parent.
- 
EventReaderDelegateConstruct an filter with the specified parent.- Parameters:
- reader- the parent
 
 
- 
- 
Method Details- 
setParentSet the parent of this instance.- Parameters:
- reader- the new parent
 
- 
getParentGet the parent of this instance.- Returns:
- the parent or null if none is set
 
- 
nextEventDescription copied from interface:XMLEventReaderGets the next XMLEvent. The initial event isStartDocument.- Specified by:
- nextEventin interface- XMLEventReader
- Returns:
- the next XMLEvent
- Throws:
- XMLStreamException- if there is an error with the underlying XML.

next
- 
hasNextpublic boolean hasNext()Description copied from interface:XMLEventReaderCheck if there are more events. Returns true if there are more events and false otherwise.- Specified by:
- hasNextin interface- Iterator<Object>
- Specified by:
- hasNextin interface- XMLEventReader
- Returns:
- true if the event reader has more events, false otherwise
 
- 
peekDescription copied from interface:XMLEventReaderCheck 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:
- peekin interface- XMLEventReader
- Returns:
- the next XMLEvent
- Throws:
- XMLStreamException- if an error occurs
- See Also:
 
- 
closeDescription copied from interface:XMLEventReaderFrees any resources associated with this Reader. This method does not close the underlying input source.- Specified by:
- closein interface- XMLEventReader
- Throws:
- XMLStreamException- if there are errors freeing associated resources
 
- 
getElementTextDescription copied from interface:XMLEventReaderReads 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:
- getElementTextin interface- XMLEventReader
- Returns:
- the text of the element
- Throws:
- XMLStreamException- if the current event is not a START_ELEMENT or if a non text element is encountered
 
- 
nextTagDescription copied from interface:XMLEventReaderSkips 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:
- nextTagin interface- XMLEventReader
- Returns:
- a START_ELEMENT or END_ELEMENT
- Throws:
- XMLStreamException- if anything other than space characters are encountered
 
- 
getPropertyDescription copied from interface:XMLEventReaderGet the value of a feature/property from the underlying implementation- Specified by:
- getPropertyin interface- XMLEventReader
- Parameters:
- name- The name of the property
- Returns:
- The value of the property
- Throws:
- IllegalArgumentException- if the property is not supported
