SizedSink

class SizedSink extends Sink

An in-memory circular buffer of events. When capacity is reached, new writes via event do not block, rather they overwrite the oldest event.

This class is thread-safe and effort is taken to keep object allocations from calls to event to a minimum.

    Event input is captured as individual fields in service of avoiding an allocation to wrap the event.

    if (sink.recording) {

    Whether or not this sink should be recording events.

    Whether or not this sink should be recording events.

    This is external to the event() and managed by caller because there is some expense in capturing the data sent to that call.

    The expectation is for callers to do:

    if (sink.recording) {
    sink.event(...)
    }
