Interface ParserDelegate

All Superinterfaces:

ContentHandler

All Known Implementing Classes:

FESParserDelegate, FilterParserDelegate, GMLParserDelegate, GMLParserDelegate, InterpolationParserDelegate, ParameterParserDelegate, QueryExpressionTextDelegate, RangeSubsetParserDelegate, ScalingParserDelegate, WFSParserDelegate, XSDParserDelegate

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 Summary

Modifier and Type	Method and Description
boolean	canHandle(QName elementName) Deprecated. This method is deprecated and ParserDelegate2#canHandle(QName, Attributes, Handler) should be used. After one major release cycle ParserDelegate2 methods will be pulled into this interface and this method will be removed. In preparation implementations should implement both interfaces.
Object	getParsedObject() Gets the final parsed object from the delegate.

Method Detail

canHandle

boolean canHandle(QName elementName)

Deprecated. This method is deprecated and ParserDelegate2#canHandle(QName, Attributes, Handler) should be used. After one major release cycle ParserDelegate2 methods will be pulled into this interface and this method will be removed. In preparation implementations should implement both interfaces.

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.

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.
