code_change(OldVsn, State, Extra) -> {ok, NewState}
Convert process state when code is changed
handle_call(Tkvstore_get::Request, From, State) -> {reply, Reply, State} | {reply, Reply, State, Timeout} | {noreply, State} | {noreply, State, Timeout} | {stop, Reason, Reply, State} | {stop, Reason, State}
Fetch persistent data, first check the data dict that is still being written
handle_cast(Tkvstore_put::Msg, State) -> {noreply, State} | {noreply, State, Timeout} | {stop, Reason, State}
Put request, copy to the writer, keep a local copy of the data
handle_info(Info, State) -> {noreply, State} | {noreply, State, Timeout} | {stop, Reason, State}
Handling all non call/cast messages
init(Args) -> {ok, State} | {ok, State, Timeout} | ignore | {stop, Reason}
Initiates the server.
pid_observe_tkvstore_delete(Pid, Tkvstore_delete, Context) -> any()
Delete the persistent data of a type/key
pid_observe_tkvstore_get(Pid, Tkvstore_get, Context) -> any()
Fetch the persistent data of a type/key
pid_observe_tkvstore_put(Pid, Tkvstore_put, Context) -> any()
Do a put in the persistent store, replace existing key/value
start_link() -> {ok, Pid} | ignore | {error, Error}
Starts the server
start_link(Args) -> any()
terminate(Reason, State) -> void()
This function is called by a gen_server when it is about to terminate. It should be the opposite of Module:init/1 and do any necessary cleaning up. When it returns, the gen_server terminates with Reason. The return value is ignored.
writer_loop(KVStorePid, Context) -> any()
Simple writer loop, started as a process
