This refactoring takes a careful approach to avoid rushing the change: * stub headers are left in all the old locations of webrtc/base * existing GN targets are kept and now just forward to the moved ones using public_deps. The only exception to the above is the base_java target and its .java files, which were moved to webrtc/rtc_base right away since it's not possible to use public_deps for android_library. To avoid breaking builds, a temporary Dummy.java file was added to the new intermediate target in webrtc/rtc_base:base_java as well to avoid hitting a GN assert in the android_library template. The above approach should make the transition smooth without breaking downstream. A helper script was created (https://codereview.webrtc.org/2879203002/) and was run like this: stub-headers.py -s webrtc/base -d webrtc/rtc_base -i 7634 stub-headers.py -s webrtc/base/numerics -d webrtc/rtc_base/numerics -i 7634 Fixed invalid header guards in the following files: webrtc/base/base64.h webrtc/base/cryptstring.h webrtc/base/event.h webrtc/base/flags.h webrtc/base/httpbase.h webrtc/base/httpcommon-inl.h webrtc/base/httpcommon.h webrtc/base/httpserver.h webrtc/base/logsinks.h webrtc/base/macutils.h webrtc/base/nattypes.h webrtc/base/openssladapter.h webrtc/base/opensslstreamadapter.h webrtc/base/pathutils.h webrtc/base/physicalsocketserver.h webrtc/base/proxyinfo.h webrtc/base/sigslot.h webrtc/base/sigslotrepeater.h webrtc/base/socket.h webrtc/base/socketaddresspair.h webrtc/base/socketfactory.h webrtc/base/stringutils.h webrtc/base/testbase64.h webrtc/base/testutils.h webrtc/base/transformadapter.h webrtc/base/win32filesystem.h Added new header guards to: sslroots.h testbase64.h BUG=webrtc:7634 NOTRY=True NOPRESUBMIT=True R=kwiberg@webrtc.org Review-Url: https://codereview.webrtc.org/2877023002 .

|
|
|
// 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
