Methods #
static setEnabled(enabled) #
static isEnabled() #
static beginEvent(profileName?, args?) #
beginEvent/endEvent for starting and then ending a profile within the same call stack frame
static endEvent() #
static beginAsyncEvent(profileName?) #
beginAsyncEvent/endAsyncEvent for starting and then ending a profile where the end can either occur on another thread or out of the current stack frame, eg await the returned cookie variable should be used as input into the endAsyncEvent call to end the profile
static endAsyncEvent(profileName?, cookie?) #
static counterEvent(profileName?, value?) #
counterEvent registers the value to the profileName on the systrace timeline
static attachToRelayProfiler(relayProfiler) #
Relay profiles use await calls, so likely occur out of current stack frame therefore async variant of profiling is used
static swizzleJSON() #
This is not called by default due to perf overhead but it's useful
