Message:

Add Clock class and platform-specific implementations.
​https://bugs.webkit.org/show_bug.cgi?id=71341

Reviewed by Sam Weinig.

Source/JavaScriptCore:

Add WTF_USE_COREAUDIO macro for use by PlatformClockCA.

  • wtf/Platform.h:

Source/WebCore:

No new tests; these classes will be used and tested by the MediaController feature.

Adds a abstract Clock class and two concrete, platform-specific subclasses.

Clock provides a basic interface for starting, stopping, and querying a generic timeline.
PlatformClockCA implements this interface using a CoreAudio CAClock object, which uses
the default audio device's hardware clock as a timing source. PlatformClockPOSIX
implements this interface using gettimeofday() as its timing source.

  • WebCore.xcodeproj/project.pbxproj:
  • platform/Clock.cpp: Added.

(Clock::create): Creates a platform-specific clock.

  • platform/Clock.h: Added.

(WebCore::Clock::~Clock):
(WebCore::Clock::Clock):

  • platform/mac/PlatformClockCA.cpp: Added.
