Interface StAXStreamProcessor

All Known Implementing Classes:

AbstractStAXStreamProcessor

public interface StAXStreamProcessor

This interface provides a base support for the XMLOutputter.

People who want to create a custom XMLOutputProcessor for XMLOutputter are able to implement this interface with the following notes and restrictions:

1. The XMLOutputter will call one, and only one of the process(XMLStreamWriter,Format,*) methods each time the XMLOutputter is requested to output some JDOM content. It is thus safe to assume that a process(XMLStreamWriter,Format,*) method can set up any infrastructure needed to process the content, and that the XMLOutputter will not re-call that method, or some other process(XMLStreamWriter,Format,*) method for the same output sequence.
2. The process methods should be thread-safe and reentrant: The same process(XMLStreamWriter,Format,*) method may (will) be called concurrently from different threads.

The AbstractXMLOutputProcessor class is a full implementation of this interface and is fully customisable. People who want a custom XMLOutputter are encouraged to extend the AbstractXMLOutputProcessor rather than do a full re-implementation of this interface.

Method Details

process

void process(XMLStreamWriter out,
 Format format,
 Document doc)
      throws XMLStreamException

This will print the Document to the given XMLStreamWriter.

Warning: using your own XMLStreamWriter may cause the outputter's preferred character encoding to be ignored. If you use encodings other than UTF-8, we recommend using the method that takes an OutputStream instead.

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

doc - Document to format.

Throws:

XMLStreamException - if there's any problem writing.

NullPointerException - if the input content is null

process

void process(XMLStreamWriter out,
 Format format,
 DocType doctype)
      throws XMLStreamException

Print out the DocType.

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

doctype - DocType to output.

Throws:

XMLStreamException - if there's any problem writing.

NullPointerException - if the input content is null

process

void process(XMLStreamWriter out,
 Format format,
 Element element)
      throws XMLStreamException

Print out an Element, including its Attributes, and all contained (child) elements, etc.

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

element - Element to output.

Throws:

XMLStreamException - if there's any problem writing.

NullPointerException - if the input content is null

process

void process(XMLStreamWriter out,
 Format format,
 List<? extends Content> list)
      throws XMLStreamException

This will handle printing out a list of nodes. This can be useful for printing the content of an element that contains HTML, like "<description>JDOM is <b>fun>!</description>".

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

list - List of nodes.

Throws:

XMLStreamException - if there's any problem writing.

NullPointerException - if the input list is null or contains null members

ClassCastException - if any of the list members are not Content

process

void process(XMLStreamWriter out,
 Format format,
 CDATA cdata)
      throws XMLStreamException

Print out a CDATA node.

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

cdata - CDATA to output.

Throws:

XMLStreamException - if there's any problem writing.

NullPointerException - if the input content is null

process

void process(XMLStreamWriter out,
 Format format,
 Text text)
      throws XMLStreamException

Print out a Text node. Perfoms the necessary entity escaping and whitespace stripping.

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

text - Text to output.

Throws:

XMLStreamException - if there's any problem writing.

NullPointerException - if the input content is null

process

void process(XMLStreamWriter out,
 Format format,
 Comment comment)
      throws XMLStreamException

Print out a Comment.

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

comment - Comment to output.

Throws:

XMLStreamException - if there's any problem writing.

NullPointerException - if the input content is null

process

void process(XMLStreamWriter out,
 Format format,
 ProcessingInstruction pi)
      throws XMLStreamException

Print out a ProcessingInstruction.

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

pi - ProcessingInstruction to output.

Throws:

XMLStreamException - if there's any problem writing.

NullPointerException - if the input content is null

process

void process(XMLStreamWriter out,
 Format format,
 EntityRef entity)
      throws XMLStreamException

Print out a EntityRef.

Parameters:

out - XMLStreamWriter to use.

format - Format instance specifying output style

entity - EntityRef to output.
