Interface XMLOutputProcessor

All Known Implementing Classes:

AbstractXMLOutputProcessor

public interface XMLOutputProcessor

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(Writer,Format,*) methods each time the XMLOutputter is requested to output some JDOM content. It is thus safe to assume that a process(Writer,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(Writer,Format,*) method for the same output sequence.
2. The process methods should be thread-safe and reentrant: The same process(Writer,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 Detail

process

void process(java.io.Writer out,
             Format format,
             Document doc)
      throws java.io.IOException

This will print the Document to the given Writer.

Warning: using your own Writer 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 - Writer to use.

format - Format instance specifying output style

doc - Document to format.

Throws:

java.io.IOException - if there's any problem writing.

java.lang.NullPointerException - if the input content is null

process

void process(java.io.Writer out,
             Format format,
             DocType doctype)
      throws java.io.IOException

Print out the DocType.

Parameters:

out - Writer to use.

format - Format instance specifying output style

doctype - DocType to output.

Throws:

java.io.IOException - if there's any problem writing.

java.lang.NullPointerException - if the input content is null

process

void process(java.io.Writer out,
             Format format,
             Element element)
      throws java.io.IOException

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

Parameters:

out - Writer to use.

format - Format instance specifying output style

element - Element to output.

Throws:

java.io.IOException - if there's any problem writing.

java.lang.NullPointerException - if the input content is null

process

void process(java.io.Writer out,
             Format format,
             java.util.List<? extends Content> list)
      throws java.io.IOException

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 - Writer to use.

format - Format instance specifying output style

list - List of nodes.

Throws:

java.io.IOException - if there's any problem writing.

java.lang.NullPointerException - if the input list is null or contains null members

java.lang.ClassCastException - if any of the list members are not Content
