Reason for revert:
Breaks lots of downstream projects.
Original issue's description:
> Remove remains of webrtc/base
>
> All downstream code have been updated to the new location.
>
> In PRESUBMIT.py:
> * Remove webrtc/rtc_base from CPP_BLACKLIST
> * Add webrtc/rtc_base to LEGACY_API_DIRS
>
> Fix some duplicated paths in
> webrtc/modules/audio_processing/test/conversational_speech/BUILD.gn

// To generate callback.h from callback.h.pump, execute:

|
|
|
// Callbacks are callable object containers. They can hold a function pointer
|
|
// or a function object and behave like a value type. Internally, data is
|
|
// reference-counted, making copies and pass-by-value inexpensive.
|
|
//
|
|
// Callbacks are typed using template arguments. The format is:
|
|
// CallbackN<ReturnType, ParamType1, ..., ParamTypeN>
|
|
// where N is the number of arguments supplied to the callable object.
|
|
// Callbacks are invoked using operator(), just like a function or a function
|
|
// object. Default-constructed callbacks are "empty," and executing an empty
|
|
// callback does nothing. A callback can be made empty by assigning it from
|
|
// a default-constructed callback.
|
|
//
|
|
// Callbacks are similar in purpose to std::function (which isn't available on
|
|
// all platforms we support) and a lightweight alternative to sigslots. Since
|
|
// they effectively hide the type of the object they call, they're useful in
|
|
// breaking dependencies between objects that need to interact with one another.
|
|
// Notably, they can hold the results of Bind(), std::bind*, etc, without
|
|
// needing
|
|
// to know the resulting object type of those calls.
|
|
//
|
|
// Sigslots, on the other hand, provide a fuller feature set, such as multiple
|
|
// subscriptions to a signal, optional thread-safety, and lifetime tracking of
|
|
// slots. When these features are needed, choose sigslots.
|
|
//
|
|
// Example:
|
|
// int sqr(int x) { return x * x; }
|
|
// struct AddK {
|
|
// int k;
|
|
// int operator()(int x) const { return x + k; }
|
|
// } add_k = {5};
|
|
//
|
|
// Callback1<int, int> my_callback;
|
|
// cout << my_callback.empty() << endl; // true
|
|
//
|
|
// my_callback = Callback1<int, int>(&sqr);
|
|
// cout << my_callback.empty() << endl; // false
|
|
// cout << my_callback(3) << endl; // 9
|
|
//
|
|
// my_callback = Callback1<int, int>(add_k);
|
|
// cout << my_callback(10) << endl; // 15
|
|
//
|
|
// my_callback = Callback1<int, int>();
|
|
// cout << my_callback.empty() << endl; // true
