Constructor Detail

MessageExchange

public MessageExchange(InetSocketAddress target,
                       String serviceName,
                       TextProtocol.RequestMessage request)

Method Detail

run

public void run()

Specified by:

run in interface Runnable

messageExchange

public void messageExchange()

Run a message exchange. A successful exchange results in a response message being set. All failures result in the response message being null and an exception being set.

setResponseMessage

public void setResponseMessage(TextProtocol.ResponseMessage responseMessage)

getResponseMessage

public TextProtocol.ResponseMessage getResponseMessage()

Returns the response message. The null may be returned as part of the protocol exchange, or it may be null if an exception was encountered say because of some IO problem. It's the caller's responsibility to check for an exception in that circumstance.

Note: there may be some protocols (e.g., Monitor) that define null to be a proper, expected response upon success. It might be preferable to redefine them to return an explicit OK response, if possible.

Returns:

the response

getRequestMessage

public TextProtocol.RequestMessage getRequestMessage()

getException

public Exception getException()
