    private static class SettingsTransformer.FixCodeCacheSink
    extends java.lang.Object
    implements IEventSink
    Fix for JDK-8157024, the code cache stats unallocatedCapacity event is written as KiB but reported as B. This is fixed in JDK9, but we need to perform this transformation for recordings from JDK8 and earlier.

        public void addEvent​(java.lang.Object[] values)
        Description copied from interface: IEventSink
        Add a new event to the sink for processing. The sink may modify the event values as it sees fit.

        The implementation should have one or more subsinks created during the IEventSinkFactory.create call. Call addEvent on a subsink to continue the processing of the event. Note that the passed on value array must match the data structure used by the subsink.

        If no addEvent call is made to a subsink, then the event will be effectively filtered out.

        addEvent calls to subsinks may be delayed until later calls of this method or in an implementation specific flush method that can be called by IEventSinkFactory.flush.

        Specified by:
        addEvent in interface IEventSink
        Parameters:
        values - Event values. The order and data type of the values must match the dataStructure parameter to the IEventSinkFactory.create call.
