Class RPCHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      org.jboss.axis.message.SOAPHandler (src) 
          org.jboss.axis.message.RPCHandler

All Implemented Interfaces:: org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public class RPCHandler
extends SOAPHandler (src)

This is the SOAPHandler which is called for each RPC parameter as we're deserializing the XML for a method call or return. In other words for this XML:

Hello! 3.14159

...we'll get onStartChild() events for and .

Constructor Detail

RPCHandler

public RPCHandler(RPCElement (src)  rpcElem,
                  boolean isResponse)

Method Detail

setOperation

public void setOperation(OperationDesc (src)  myOperation)

setHeaderElement

public void setHeaderElement(boolean value)

Indicate RPCHandler is processing header elements

Parameters:: value - boolean indicating whether header elements are being processed.

startElement

public void startElement(java.lang.String namespace,
                         java.lang.String localName,
                         java.lang.String prefix,
                         org.xml.sax.Attributes attributes,
                         DeserializationContext (src)  context)
                  throws org.xml.sax.SAXException

This method is invoked when an element start tag is encountered. The purpose of this method in RPCHandler is to reset variables (this allows re-use of RPCHandlers)

Overrides:: startElement in class SOAPHandler (src)

Parameters:: namespace - is the namespace of the element; localName - is the name of the element; prefix - is the prefix of the element; attributes - are the attributes on the element...used to get the type; context - is the DeserializationContext
Throws:: org.xml.sax.SAXException

onStartChild

public SOAPHandler (src)  onStartChild(java.lang.String namespace,
                                java.lang.String localName,
                                java.lang.String prefix,
                                org.xml.sax.Attributes attributes,
                                DeserializationContext (src)  context)
                         throws org.xml.sax.SAXException

Our job here is to figure out a) which parameter this is (based on the QName of the element or its position), and b) what type it is (based on the xsi:type attribute or operation metadata) so we can successfully deserialize it.

Overrides:: onStartChild in class SOAPHandler (src)

Throws:: org.xml.sax.SAXException

endElement

public void endElement(java.lang.String namespace,
                       java.lang.String localName,
                       DeserializationContext (src)  context)
                throws org.xml.sax.SAXException
