Method Detail

handle

void handle(Message request,
            Response response)
     throws java.lang.Exception

Invokes a request. This should be done asynchronously, e.g. by dispatching this to a thread pool. When done, if a response is needed (e.g. in case of a sync RPC), Response.send(Object,boolean) should be called.

Parameters:

request - The request

response - The response implementation. Contains information needed to send the reply (e.g. a request ID). If no response is required, e.g. because this is an asynchronous RPC, then response will be null.

Throws:

java.lang.Exception - If an exception is thrown (e.g. in case of an issue submitting the request to a thread pool, the exception will be taken as return value and will be sent as a response. In this case, Response.send(Object,boolean) must not be called
