Invoke
ffor every Gc event in the system.Invoke
ffor every Gc event in the system. This samplessnapin order to synthesize a unique stream of Gc events. It's important thatfis not constructed so that it's likely to, by itself, trigger another Gc event, causing an infinite loop. The same is true of the internal datastructures used by foreachGc, but they are svelte. - final def getClass(): Class[_ <: AnyRef]

Get the main class name for the currently running application.
Get the main class name for the currently running application. Note that this works only by heuristic, and may not be accurate.

foreachGc, and returns a function to query its timeline (up tobufferin the past). Querying is cheap, linear to the number of Gcs that happened since the queried time. The result is returned in reverse chronological order.- Definition Classes
