class KeyEqualsFinder extends MonitorMatchFinder with StrictLogging

A simple match finder that checks for equivalent keys.

This class will work with byte arrays or any object that has a working equals implementation (for example, String).

This class will attempt to handle multiple occurences of the same key by storing the most recent reference topic offset that a key has been seen at and then ignoring any reference message that occur before that offset. This implementation is most efficient if your keys are Strings or if they are objects that have a working toString method. Byte arrays will have to be SHA-1 hashed and converted to a hex string internally for us with this finder.

This finder will periodically do garbage collection on its internal map of seen keys to avoid blowing the heap. The actual collection will occur outside of the main thread and remove keys whose last seen offset is less than 1000 less than the current start offset of the reference window.

  9. def find(testMessage: MonitorObjectEnvelope, referenceWindow: Seq[MonitorObjectEnvelope]): MonitorMatchFindResult

    Looks for a reference message in the provided referenceWindow that should match the given testMessage.

    Looks for a reference message in the provided referenceWindow that should match the given testMessage.

    testMessage

    The message that came from the test topic

    referenceWindow

    The window of messages available for consideration from the reference topic

    returns

    A MonitorMatchFindResult based on whether or not a match was found.
