invokeEndpointMethod

public void invokeEndpointMethod(java.util.concurrent.Executor executor,
                                 java.lang.Runnable invocation)

Runs a web socket invocation, setting up the threads and dispatching a thread pool

Unfortunately we need to dispatch to a thread pool, because there is a good chance that the endpoint will use blocking IO methods. We suspend recieves while this is in progress, to make sure that we do not have multiple methods invoked at once.

Parameters:

invocation - The task to run

invokeEndpointMethod

public void invokeEndpointMethod(java.lang.Runnable invocation)

Directly invokes an endpoint method, without dispatching to an executor

Parameters:

invocation - The invocation
