Class XMLOutputter

java.lang.Object
  org.znerd.xmlenc.XMLOutputter

All Implemented Interfaces:: StatefulXMLEventListener, XMLEventListener, XMLEventListenerStates

public class XMLOutputter
extends Object
implements StatefulXMLEventListener

Stream-based XML outputter. Instances of this class are able to write XML output to Writers.

Standards compliance

This class is intended to produce output that conforms to the XML 1.0 Specification. However, not all applicable restrictions are validated. For example, it is currently not checked if names contain characters that are invalid within a Name production.

Furthermore, not all possible XML documents can be produced. The following limitations apply:

The name of the applicable encoding is always printed in the XML declaration, even though it may not be necessary.
The standalone attribute is not supported in the XML declaration.
Internal DTD subsets are not supported.
Spacing is fixed, whitespace is always kept to the minimum.

Supported encodings

The following encodings are supported:

UTF-8
UTF-16
ISO-10646-UCS-2
ISO-10646-UCS-4
ISO-10646-UTF-1
US-ASCII (also known as ASCII)
ISO-8859-n, where n is the part number

Multi-threading

This class is not thread-safe.

Exceptions

Note that all methods check the state first and then check the arguments. This means that if the state is incorrect and the arguments are incorrect, then an IllegalStateException will be thrown.

If any of the writing methods generates an IOException, then the state will be set to XMLEventListenerStates.ERROR_STATE and no more output can be performed.

Performance hints

It is usually a good idea to let XMLOutputter instances write to buffered Writers. This typically improves performance on large documents or relatively slow or blocking output streams.

Instances of this class can be cached in a pool to reduce object creations. Call reset() (with no arguments) when storing an instance in the pool. Use reset(Writer,String) (with 2 arguments) to re-initialize the instance after fetching it from the pool.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 or alternatively, if only the system identifier is specified:

 <!DOCTYPE html SYSTEM "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">


Specified by:
dtd in interface XMLEventListener


Parameters:
name - the name of the document type, not null.

                          IOException

Writes the specified comment. The comment should not contain the string
 "--".

 If the state equals XMLEventListenerStates.BEFORE_XML_DECLARATION, then it will be set to
 XMLEventListenerStates.BEFORE_DTD_DECLARATION, otherwise if the state is
 XMLEventListenerStates.START_TAG_OPEN then it will be set to XMLEventListenerStates.WITHIN_ELEMENT,
 otherwise the state will not be changed.


Specified by:
comment in interface XMLEventListener


Parameters:
text - the text for the comment be written, not null.
Throws:
IllegalStateException - if getState() != XMLEventListenerStates.BEFORE_XML_DECLARATION &&
             getState() != XMLEventListenerStates.BEFORE_DTD_DECLARATION &&
             getState() != XMLEventListenerStates.BEFORE_ROOT_ELEMENT &&
             getState() != XMLEventListenerStates.START_TAG_OPEN &&
             getState() != XMLEventListenerStates.WITHIN_ELEMENT &&
             getState() != XMLEventListenerStates.AFTER_ROOT_ELEMENT.
IllegalArgumentException - if text == null.
InvalidXMLException - if the specified text contains an invalid character.
IOException - if an I/O error occurs; this will set the state to
    XMLEventListenerStates.ERROR_STATE.





pi
public final void pi(String target,
                     String instruction)
              throws IllegalStateException,
                     IllegalArgumentException,
                     IOException

Writes a processing instruction. A target and an optional instruction
 should be specified.

 A processing instruction can appear above and below the root
 element, and between elements. It cannot appear inside an element start
 or end tag, nor inside a comment. Processing instructions cannot be
 nested.

 
If the state equals XMLEventListenerStates.BEFORE_XML_DECLARATION, then it will be set to
 XMLEventListenerStates.BEFORE_DTD_DECLARATION, otherwise the state will not be
 changed.


Specified by:
pi in interface XMLEventListener


Parameters:
target - an identification of the application at which the instruction is
    targeted, not null.
instruction - the instruction, can be null, which is equivalent to an
    empty string.
Throws:
IllegalStateException - if getState() != XMLEventListenerStates.BEFORE_XML_DECLARATION &&
             getState() != XMLEventListenerStates.BEFORE_DTD_DECLARATION &&
             getState() != XMLEventListenerStates.BEFORE_ROOT_ELEMENT &&
             getState() != XMLEventListenerStates.START_TAG_OPEN &&
             getState() != XMLEventListenerStates.WITHIN_ELEMENT &&
             getState() != XMLEventListenerStates.AFTER_ROOT_ELEMENT.
IllegalArgumentException - if target == null.
IOException - if an I/O error occurs; this will set the state to
    XMLEventListenerStates.ERROR_STATE.





cdata
public final void cdata(String text)
                 throws IllegalStateException,
                        IllegalArgumentException,
                        IOException

Writes a CDATA section.

 A CDATA section can contain any string, except
 "]]>". This will, however, not be checked by this
 method.

 
Left angle brackets and ampersands will be output in their literal
 form; they need not (and cannot) be escaped using
 "&lt;" and "&amp;".

 
If the specified string is empty (i.e.
 "".equals(text), then nothing will be output.

 
If the specified string contains characters that cannot be printed
 in this encoding, then the result is undefined.


Specified by:
cdata in interface XMLEventListener


Parameters:
text - the contents of the CDATA section, not null.
Throws:
IllegalStateException - if getState() != XMLEventListenerStates.START_TAG_OPEN &&
             getState() != XMLEventListenerStates.WITHIN_ELEMENT
IllegalArgumentException - if text == null.
IOException - if an I/O error occurs; this will set the state to
    XMLEventListenerStates.ERROR_STATE.





close
public final void close()
                 throws IllegalStateException,
                        IOException

Closes all open elements. After calling this method, only the
 whitespace(String) method can be called.

 If you would like to flush the output stream as well, call
 endDocument() instead.






Throws:
IllegalStateException - if getState() != XMLEventListenerStates.START_TAG_OPEN &&
             getState() != XMLEventListenerStates.WITHIN_ELEMENT &&
             getState() != XMLEventListenerStates.AFTER_ROOT_ELEMENT
IOException - if an I/O error occurs; this will set the state to
    XMLEventListenerStates.ERROR_STATE.





endDocument
public final void endDocument()
                       throws IllegalStateException,
                              IOException

Ends the XML output. All open elements will be closed and the underlying
 output stream will be flushed using
 getWriter().flush().

 After calling this method, no more output can be
 written until this outputter is reset.


Specified by:
endDocument in interface XMLEventListener



Throws:
IllegalStateException - if getState() != XMLEventListenerStates.START_TAG_OPEN &&
             getState() != XMLEventListenerStates.WITHIN_ELEMENT &&
             getState() != XMLEventListenerStates.AFTER_ROOT_ELEMENT.
IOException - if an I/O error occurs; this will set the state to
    XMLEventListenerStates.ERROR_STATE.
