java.lang.Object
- javax.xml.stream.util.StreamReaderDelegate

All Implemented Interfaces:

XMLStreamConstants, XMLStreamReader
```
public class StreamReaderDelegate
extends Object
implements XMLStreamReader
```
This is the base class for deriving an XMLStreamReader filter This class is designed to sit between an XMLStreamReader and an application's XMLStreamReader. By default each method does nothing but call the corresponding method on the parent interface.

Since:

1.6

Version:

    reader - the new parent
  - getParent
```
public XMLStreamReader getParent()
```
    Get the parent of this instance.
    
    Returns:
    
    the parent or null if none is set
  - next
```
public int next()
         throws XMLStreamException
```
    Description copied from interface: XMLStreamReader
    
    Get next parsing event - a processor may return all contiguous character data in a single chunk, or it may split it into several chunks. If the property javax.xml.stream.isCoalescing is set to true element content must be coalesced and only one CHARACTERS event must be returned for contiguous element content or CDATA Sections. By default entity references must be expanded and reported transparently to the application. An exception will be thrown if an entity reference cannot be expanded. If element content is empty (i.e. content is "") then no CHARACTERS event will be reported.
    Given the following XML:
    <foo>content text<![CDATA[<greeting>Hello</greeting>]]>other content</foo>
    The behavior of calling next() when being on foo will be:
    1- the comment (COMMENT)
    2- then the characters section (CHARACTERS)
    3- then the CDATA section (another CHARACTERS)
    4- then the next characters section (another CHARACTERS)
    5- then the END_ELEMENT
    
    NOTE: empty element (such as <tag/>) will be reported with two separate events: START_ELEMENT, END_ELEMENT - This preserves parsing equivalency of empty element to <tag></tag>. This method will throw an IllegalStateException if it is called after hasNext() returns false.
    
    Specified by:
    
    next in interface XMLStreamReader
    
    Returns:
    
    the integer code corresponding to the current parse event
    
    Throws:
    
    XMLStreamException - if there is an error processing the underlying XML source

  - nextTag
```
public int nextTag()
            throws XMLStreamException
```
    Description copied from interface: XMLStreamReader
    Skips any white space (isWhiteSpace() returns true), COMMENT, or PROCESSING_INSTRUCTION, until a START_ELEMENT or END_ELEMENT is reached. If other than white space characters, COMMENT, PROCESSING_INSTRUCTION, START_ELEMENT, END_ELEMENT are encountered, an exception is thrown. This method should be used when processing element-only content seperated by white space.
    Precondition: none
    Postcondition: the current event is START_ELEMENT or END_ELEMENT and cursor may have moved over any whitespace event.
    Essentially it does the following (implementations are free to optimized but must do equivalent processing):
```
 int eventType = next();
 while((eventType == XMLStreamConstants.CHARACTERS && isWhiteSpace()) // skip whitespace
 || (eventType == XMLStreamConstants.CDATA && isWhiteSpace())
 // skip whitespace
 || eventType == XMLStreamConstants.SPACE
 || eventType == XMLStreamConstants.PROCESSING_INSTRUCTION
 || eventType == XMLStreamConstants.COMMENT
 ) {
 eventType = next();
 }
 if (eventType != XMLStreamConstants.START_ELEMENT && eventType != XMLStreamConstants.END_ELEMENT) {
 throw new String XMLStreamException("expected start or end tag", getLocation());
 }
 return eventType;
 
```
    Specified by:
    
    nextTag in interface XMLStreamReader
    
    Returns:
    
    the event type of the element read (START_ELEMENT or END_ELEMENT)
    
    Throws:
    
    XMLStreamException - if the current event is not white space, PROCESSING_INSTRUCTION, START_ELEMENT or END_ELEMENT
  - getElementText
```
public String getElementText()
                      throws XMLStreamException
```
    Description copied from interface: XMLStreamReader
    Reads the content of a text-only element, an exception is thrown if this is not a text-only element. Regardless of value of javax.xml.stream.isCoalescing this method always returns coalesced content.
    Precondition: the current event is START_ELEMENT.
    Postcondition: the current event is the corresponding END_ELEMENT.
    The method does the following (implementations are free to optimized but must do equivalent processing):
```
 if(getEventType() != XMLStreamConstants.START_ELEMENT) {
 throw new XMLStreamException(
 "parser must be on START_ELEMENT to read next text", getLocation());
 }
 int eventType = next();
 StringBuffer content = new StringBuffer();
 while(eventType != XMLStreamConstants.END_ELEMENT ) {
 if(eventType == XMLStreamConstants.CHARACTERS
 || eventType == XMLStreamConstants.CDATA
 || eventType == XMLStreamConstants.SPACE
 || eventType == XMLStreamConstants.ENTITY_REFERENCE) {
 buf.append(getText());
 } else if(eventType == XMLStreamConstants.PROCESSING_INSTRUCTION
 || eventType == XMLStreamConstants.COMMENT) {
 // skipping
 } else if(eventType == XMLStreamConstants.END_DOCUMENT) {
 throw new XMLStreamException(
 "unexpected end of document when reading element text content", this);
 } else if(eventType == XMLStreamConstants.START_ELEMENT) {
 throw new XMLStreamException(
 "element text content may not contain START_ELEMENT", getLocation());
 } else {
 throw new XMLStreamException(
 "Unexpected event type "+eventType, getLocation());
 }
 eventType = next();
 }
 return buf.toString();
 
```
    Specified by:
    
    getElementText in interface XMLStreamReader
    
    Throws:
    
    XMLStreamException - if the current event is not a START_ELEMENT or if a non text element is encountered

```
    Description copied from interface: XMLStreamReader
    
    Gets the the text associated with a CHARACTERS, SPACE or CDATA event. Text starting a "sourceStart" is copied into "target" starting at "targetStart". Up to "length" characters are copied. The number of characters actually copied is returned. The "sourceStart" argument must be greater or equal to 0 and less than or equal to the number of characters associated with the event. Usually, one requests text starting at a "sourceStart" of 0. If the number of characters actually copied is less than the "length", then there is no more text. Otherwise, subsequent calls need to be made until all text has been retrieved. For example: int length = 1024; char[] myBuffer = new char[ length ]; for ( int sourceStart = 0 ; ; sourceStart += length ) { int nCopied = stream.getTextCharacters( sourceStart, myBuffer, 0, length ); if (nCopied < length) break; } XMLStreamException may be thrown if there are any XML errors in the underlying source. The "targetStart" argument must be greater than or equal to 0 and less than the length of "target", Length must be greater than 0 and "targetStart + length" must be less than or equal to length of "target".

  - getTextCharacters
```
public char[] getTextCharacters()
```
    Description copied from interface: XMLStreamReader
    
    Returns an array which contains the characters from this event. This array should be treated as read-only and transient.
