Interface ExecutionMessageNotification

public interface ExecutionMessageNotification

This interface simulates the notification of an ExecutableComponent when using a proprietarily executing client. Usually this is indicated by interrupting the thread and calling RuntimeEnvironment.dispatch() . With a proprietarily executing client, the runtime service will use this method instead if there is a callback registered for it. Additionally, the client needs to reply synchronously, that is, it needs to indicate how the request will be handled.
If no callback is registered, the runtime service will only offer the requests and expect replies if appropriate.

Modifier and Type	Method and Description
de.aristaflow.adept2.model.runtimeenvironment.messages.execution.ReplyMessage<?>	dispatch(de.aristaflow.adept2.model.runtimeenvironment.messages.execution.ExecutionMessage message) Notifies the designated message to a listener, that is the runtime manager has retrieved a signal for the corresponding execution session.

Method Detail

dispatch

de.aristaflow.adept2.model.runtimeenvironment.messages.execution.ReplyMessage<?> dispatch(de.aristaflow.adept2.model.runtimeenvironment.messages.execution.ExecutionMessage message)

Notifies the designated message to a listener, that is the runtime manager has retrieved a signal for the corresponding execution session.
Implementations have to dispatch the message and return it with the reply set appropriately if a reply is required. If no reply is required, null should be returned.
Replying positively to a state change request, for instance a CloseMessage does not mean, the execution has terminated when the reply is sent but rather the execution will close shortly.

Parameters:

message - The message providing the signal for the corresponding execution session.

Returns:

The designated message having set the reply appropriately if a reply is required, null if no reply is required. This does not need to be the very same message instance that is provided but it needs to have the same session ID.
