MqContextC - the class known as ctx or context is the application-handle of the application-server and also the main data-handle …
The context is the package-item with the required features and created by the implementation-layer-programmer. The context can be a client or a server.
The client-context-creation is triggerd by the software-workflow on demand. The client is calling the MqLinkCreate to create a connection to the server using the connection-arguments to specify the target.
The life-cycle of a client is:
ContextCreate | create and initialize the MqContextC ... |
LinkCreate | make ctx to a parent-context and setup a new client-server-link … |
SendTT | MqContextC - append a native PRIMITIVE TYPE value to the send-data-package … |
ReadTT | read a PRIMITIVE TYPE from the read-data-package … |
LinkDelete | close the client-server-link … |
ContextDelete | Destructor - delete a MqContextC instance … |
Exit | delete the context and exit the current process or thread … |
The server-context-creation is always triggerd by the MqLinkCreate command of the client. The server is usually using a factory-constructor to call the MqContextCreate and finally to call the MqContextDelete.
The server-context is fully under control of the client.
The life-cycle of a server is:
SETUP | define a class and add the setup/cleanup code |
IServerSetup | define the server-setup-interface (callback) used on startup … |
ServiceCreate | create a link between a service-token and a service-callback … |
IServerCleanup | define the server-cleanup-interface (callback) used on cleanup … |
ServiceDelete | delete a service. … |
STARTUP | define the factory and start the listener |
FactoryAdd | add a new MqFactoryC identified by factory-identifier and defined by factory-constructor … |
FactoryNew | create a new MqContextC from a MqFactoryC … |
LinkCreate | make ctx to a parent-context and setup a new client-server-link … |
ProcessEvent | enter the event-loop and wait for an incoming service-request. … |
WORK | process the service-calls and exit on end |
ReadTT | read a PRIMITIVE TYPE from the read-data-package … |
SendTT | MqContextC - append a native PRIMITIVE TYPE value to the send-data-package … |
Exit | delete the context and exit the current process or thread … |
