Class BuildRuleDurationTracker

java.lang.Object

com.facebook.buck.core.build.stats.BuildRuleDurationTracker

public class BuildRuleDurationTracker
extends Object

Tracks the total duration of work spent on each build rule.

Computation associated with build rules are broken into several phases. Those phases are invoked from various places in CachingBuildEngine at various times and on various threads. In order to track the total duration of all of those phases combined we need some central store, i.e. this class.
