Class SettingsTransformer

  • All Implemented Interfaces:
    IEventSink
    class SettingsTransformer
extends java.lang.Object
implements IEventSink
    Event sink that transforms pre JDK 11 event types to their equivalent JDK 11 types. JDK 11 input data will be passed through mostly untouched.

      • addEvent

        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.
