public class HybridServiceServlet
extends RpcServlet
implements SerializationPolicyProvider

EXPERIMENTAL and subject to change. Do not use this in production code.

This RemoteServiceServlet provides support for both legacy and deRPC clients at the cost of additional runtime overhead and API complexity.

Constructor Summary

Method Summary

ClientOracle	getClientOracle() This method will return null instead of throwing an exception.
SerializationPolicy	getSerializationPolicy(java.lang.String moduleBaseURL, java.lang.String strongName) Returns a SerializationPolicy for a given module base URL and serialization policy strong name.
void	processCall(ClientOracle clientOracle, java.lang.String payload, java.io.OutputStream stream) Process a call originating from the given request.

Method Detail

getClientOracle

public ClientOracle getClientOracle()

This method will return null instead of throwing an exception.

Overrides:

getClientOracle in class RpcServlet

getSerializationPolicy

public final SerializationPolicy getSerializationPolicy(java.lang.String moduleBaseURL,
                                                        java.lang.String strongName)

Description copied from interface: SerializationPolicyProvider

Returns a SerializationPolicy for a given module base URL and serialization policy strong name.

Specified by:

getSerializationPolicy in interface SerializationPolicyProvider

Parameters:

moduleBaseURL - the URL for the module

strongName - strong name of the serialization policy for the specified module URL

Returns:

a SerializationPolicy for a given module base URL and RPC strong name; must not return null

processCall

public void processCall(ClientOracle clientOracle,
                        java.lang.String payload,
                        java.io.OutputStream stream)
                 throws SerializationException

Description copied from class: RpcServlet

Process a call originating from the given request. Uses the RPC.invokeAndStreamResponse(Object, java.lang.reflect.Method, Object[], ClientOracle, OutputStream) method to do the actual work.

Subclasses may optionally override this method to handle the payload in any way they desire (by routing the request to a framework component, for instance). The HttpServletRequest and HttpServletResponse can be accessed via the AbstractRemoteServiceServlet.getThreadLocalRequest() and AbstractRemoteServiceServlet.getThreadLocalResponse() methods.

This is public so that it can be unit tested easily without HTTP.

Overrides:

processCall in class RpcServlet

Parameters:

clientOracle - the ClientOracle that will be used to interpret the request

payload - the UTF-8 request payload

stream - the OutputStream that will receive the encoded response

Throws:

SerializationException - if we cannot serialize the response

processCall

public java.lang.String processCall(java.lang.String payload)
                             throws SerializationException

Throws:

SerializationException
