Constructor Detail

ServerInvokerCallbackHandler

public ServerInvokerCallbackHandler(InvocationRequest invocation,
                                    InvokerLocator serverLocator,
                                    ServerInvoker owner)
                             throws Exception

Method Detail

setMemPercentCeiling

public void setMemPercentCeiling(Double ceiling)

getMemPercentCeiling

public Double getMemPercentCeiling()

getCallbackClient

public Client getCallbackClient()

getId

public static String getId(InvocationRequest invocation)

Returns an id that can be used to identify this particular callback handler, which should be representative of the client invoker it will make callbacks to. Currently, this is the session id associated with the invocation request.

Returns:

getId

public String getId()

Returns an id that can be used to identify this particular callback handler, which should be representative of the client invoker it will make callbacks to.

Returns:

getCallbacks

public List getCallbacks()

isPullCallbackHandler

public boolean isPullCallbackHandler()

handleCallback

public void handleCallback(InvocationRequest callback)
                    throws HandleCallbackException

Will take the callback message and send back to client. If client locator is null, will store them till client polls to get them.

Specified by:

handleCallback in interface InvokerCallbackHandler

Parameters:

callback -

Throws:

HandleCallbackException

toString

public String toString()

Returns the id for this handler

Returns:

destroy

public void destroy()

This method is required to be called upon removing a callback listener so can clean up resources used by the handler. In particular, should call disconnect on internal Client.
