Field Detail

result

protected java.lang.Object result

The result of the XML-RPC operation. Possibly an XmlRpcException

fault

protected boolean fault

Set to true if a fault occured on the server.

Constructor Detail

public XmlRpcClientResponseProcessor(java.util.TimeZone tz)

Creates a new instance.

Method Detail

decodeResponse

public java.lang.Object decodeResponse(java.io.InputStream is)
                                throws XmlRpcClientException

Decode an XML-RPC response from the specified InputStream.

Parameters:

is - The stream from which to read the response.

Returns:

The response, which will be a XmlRpcException if an error occured.

Throws:

XmlRpcClientException

decodeException

protected XmlRpcException decodeException(java.lang.Object result)
                                   throws XmlRpcClientException

Decode an exception from the result returned from the remote server. This method both returns and throws an XmlRpcException. If it returns an XmlRpcException then that is the exception thrown on the remote side. If it throws an exception then an exception occured locally when decoding the response

Parameters:

result - The response from the remote XML-RPC server.

Returns:

A XmlRpcException describing the error which occurred.

Throws:

XmlRpcClientException - if the result could not be processed.

objectParsed

protected void objectParsed(java.lang.Object what)

Description copied from class: XmlRpc

This method is called when a root level object has been parsed. Sub-classes implement this callback to receive the fully parsed object.

Specified by:

objectParsed in class XmlRpc

startElement

public void startElement(java.lang.String name,
                org.xml.sax.AttributeList atts)
                  throws org.xml.sax.SAXException

Overrides method in XmlRpc to handle fault repsonses.

Specified by:

startElement in interface org.xml.sax.DocumentHandler

Overrides:

startElement in class XmlRpc

Parameters:

name - The element type name.

atts - The specified or defaulted attributes.

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

DocumentHandler.startElement(java.lang.String, org.xml.sax.AttributeList)

canReUse

protected boolean canReUse()

Called by the worker management framework to see if this worker can be re-used. Must attempt to clean up any state, and return true if it can be re-used.

Returns:

boolean true if this worker has been cleaned up and may be re-used.
