  13. def foreachGc(f: (Gc) ⇒ Unit): Unit

    Invoke f for every Gc event in the system.

    Invoke f for every Gc event in the system. This samples snap in order to synthesize a unique stream of Gc events. It's important that f is 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.

    Monitors Gcs using foreachGc, and returns a function to query its timeline (up to buffer in 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.
