public interface ParserDelegate
extends ContentHandler

Interface for objects which need to take over parsing control from the main parsing driver.

An example of such a case is when a schema dynamically imports content from other schemas.

Instances of these objects are declared in the Configuration.getContext(). Example:

 MyParserDelegate delegate = new MyParserDelegate();
 Configuration configuration = ...;

 configuration.getContext().registerComponentInstance( delegate );

Method Detail

canHandle

boolean canHandle(QName elementName,
                  Attributes attributes,
                  Handler handler,
                  Handler parent)

Determines if this delegate can handle the specified element name.

A common check in this method would be to check the namespace of the element.

Parameters:

elementName - The name of the element to potentially handle.

attributes - The attributes of the element to potentially handle

handler - The parse handler that would normally handle the element, possibly null

parent - The parse handler for the parent element, possibly null.

Returns:

True if this delegate handles elements of the specified name and should take over parsing.

getParsedObject

Object getParsedObject()

Gets the final parsed object from the delegate.

This method is called after parsing control returns to the main parsing driver.
