We must remove dependency on Chromium, i.e. we can't use Chromium's base/logging.h. That means we need to define these macros in WebRTC also when doing Chromium builds. And this causes redefinition. * DISALLOW_ASSIGN -> RTC_DISALLOW_ASSIGN * DISALLOW_COPY_AND_ASSIGN -> RTC_DISALLOW_COPY_AND_ASSIGN * DISALLOW_IMPLICIT_CONSTRUCTORS -> RTC_DISALLOW_IMPLICIT_CONSTRUCTORS Related CL: https://codereview.webrtc.org/1335923002/ BUG=chromium:468375 NOTRY=true Review URL: https://codereview.webrtc.org/1345433002 Cr-Commit-Position: refs/heads/master@{#9953}

// SigslotTester(s) are utility classes to check if signals owned by an

// object are being invoked at the right time and with the right arguments.

// They are meant to be used in tests. Tests must provide "capture" pointers
|
|
// (i.e. address of variables) where the arguments from the signal callback
|
|
// can be stored.
|
|
//
|
|
// Example:
|
|
// /* Some signal */
|
|
// sigslot::signal1<const std::string&> foo;
|
|
//
|
|
// /* We want to monitor foo in some test. Note how signal argument is
|
|
// const std::string&, but capture-type is std::string. Capture type
|
|
// must be type that can be assigned to. */
