How to get the event type completely depends on `getEvent`. `getEvent` can simple return a member for the first argument, or concatenate all arguments, or even hash the arguments and return the hash value as the event type. + + + +## Argument passing mode + +We have the dispatcher +```c++ +eventpp::EventDispatcher dispatcher; +``` +The event type is `int`. +The listener's first parameter is also `int`. Depending how the event is dispatched, the listener's first argument can be either the event type, or an extra argument. + +```c++ +dispatcher.dispatch(3, "hello"); +``` +The event *3* is dispatched with an argument *"hello"*, the listener will be invoked with the arguments `(3, "hello")`, the first argument is the event type. + +```c++ +dispatcher.dispatch(3, 8, "hello"); +``` +The event *3* is dispatched with two arguments *8* and *"hello"*, the listener will be invoked with the arguments `(8, "hello")`, the first argument is the extra argument, and the event type is omitted. + +So by default, EventDispatcher automatically detects the argument count of `dispatch` and listeners prototype, and calls the listeners either with or without the event type. + +The default rule is convenient, permissive, and, may be error prone. The second parameter `typename ArgumentPassingMode` in the policies can control the behavior. + +```c++ +struct ArgumentPassingAutoDetect; +struct ArgumentPassingIncludeEvent; +struct ArgumentPassingExcludeEvent; +``` + +`ArgumentPassingAutoDetect`: the default policy. Auto detects whether to pass the event type. +`ArgumentPassingIncludeEvent`: always passes the event type. If the argument count doesn't match, compiling fails. +`ArgumentPassingExcludeEvent`: always omits and doesn't pass the event type. If the argument count doesn't match, compiling fails. + +Assumes the number of arguments in the listener prototype is P, the number of arguments (include the event type) in `dispatch` is D, then the relationship of P and D is, +For `ArgumentPassingAutoDetect`: P == D or P + 1 == D +For `ArgumentPassingIncludeEvent`: P == D +For `ArgumentPassingExcludeEvent`: P + 1 == D + +**Note**: the same rules also applies to `EventDispatcher<>::enqueue`, since `enqueue` has same parameters as `dispatch`. + +Examples to demonstrate argument passing mode + +```c++ +eventpp::EventDispatcher< + int, + void(int, const std::string &), + ArgumentPassingAutoDetect +> dispatcher; +// or just +//eventpp::EventDispatcher dispatcher; +dispatcher.dispatch(3, "hello"); // Compile OK +dispatcher.dispatch(3, 8, "hello"); // Compile OK +dispatcher.enqueue(3, "hello"); // Compile OK +dispatcher.enqueue(3, 8, "hello"); // Compile OK +``` + +```c++ +eventpp::EventDispatcher< + int, + void(int, const std::string &), + ArgumentPassingIncludeEvent +> dispatcher; +dispatcher.dispatch(3, "hello"); // Compile OK +//dispatcher.dispatch(3, 8, "hello"); // Compile failure +dispatcher.enqueue(3, "hello"); // Compile OK +//dispatcher.enqueue(3, 8, "hello"); // Compile failure +``` + +```c++ +eventpp::EventDispatcher< + int, + void(int, const std::string &), + ArgumentPassingExcludeEvent +> dispatcher; +//dispatcher.dispatch(3, "hello"); // Compile failure +dispatcher.dispatch(3, 8, "hello"); // Compile OK +//dispatcher.enqueue(3, "hello"); // Compile failure +dispatcher.enqueue(3, 8, "hello"); // Compile OK +``` + +## Notes and caveats +1. If a listener adds another listener of the same event to the dispatcher during a dispatching, the new listener is guaranteed to be called within the same dispatching. Ideally the new added listener should not be called, but this is limited by the underlying data structure. + + +## Thread safety +`EventDispatcher` is thread safe. All public functions can be invoked from multiple threads simultaneously. If it failed, please report a bug. +But the operations on the listeners, such as copying, moving, comparing, or invoking, may be not thread safe. It depends on listeners. + + +## Exception safety + +EventDispatcher doesn't throw any exceptions. +Exceptions may be thrown by underlying code when, +1. Out of memory, new memory can't be allocated. +2. The listeners throw exceptions during copying, moving, comparing, or invoking. + +## Time complexities +The time complexities being discussed here is about when operating on the listener in the underlying list, and `n` is the number of listeners. It doesn't include the event searching in the underlying `std::map` which is always O(log n). +* `appendListener`: O(1) +* `prependListener`: O(1) +* `insertListener` before another handle: O(1) +* `removeListener` by handle: O(1) + +## Internal data structure + +Beside using [CallbackList](doc/callbacklist.md) to manage the listener callbacks, EventDispatcher uses three `std::list` to manage the event queue. +The first busy list holds all nodes with queued events. +The second idle list holds all idle nodes. After an event is dispatched and removed from the queue, instead of freeing the memory, EventDispatcher moves the unused node to the idle list. This can improve performance and avoid memory fragment. +The third list is a local temporary list used in function `process()`. During processing, the busy list is swapped to the temporary list, all events are dispatched from the temporary list, then the temporary list is returned and appended to the idle list. + diff --git a/include/eventpp/callbacklist.h b/include/eventpp/callbacklist.h new file mode 100644 index 0000000..9e302fa --- /dev/null +++ b/include/eventpp/callbacklist.h @@ -0,0 +1,319 @@ +// eventpp library +// Copyright (C) 2018 Wang Qi (wqking) +// Github: https://github.com/wqking/eventpp +// Licensed under the Apache License, Version 2.0 (the "License");
