Class RPCHandler


public class RPCHandler
extends SOAPHandler

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 .

RPCHandler

public RPCHandler(RPCElement rpcElem,
                  boolean isResponse)
            throws SAXException

Method Details

endElement

public void endElement(String namespace,
                       String localName,
                       DeserializationContext context)
            throws SAXException
Overrides:
endElement in interface SOAPHandler

onStartChild

public SOAPHandler onStartChild(String namespace,
                                String localName,
                                String prefix,
                                Attributes attributes,
                                DeserializationContext context)
            throws SAXException
Register the start of a parameter (child element of the method call element). 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 interface SOAPHandler

setHeaderElement

public void setHeaderElement(boolean value)
Indicate RPCHandler is processing header elements
Parameters:
value - boolean indicating whether header elements are being processed.

setOperation

public void setOperation(OperationDesc myOperation)

startElement

public void startElement(String namespace,
                         String localName,
                         String prefix,
                         Attributes attributes,
                         DeserializationContext context)
            throws 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 interface SOAPHandler
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
