Interface InstrumentationFacility

  • All Known Implementing Classes:
    InstrumentationFacility_impl

    public interface InstrumentationFacility
    The InstrumentationFacility interface defines a standard way for UIMA components to be instrumented for performance evaluation. The UIMA framework will provide each UIMA component with access to an implementation of this interface. This interface is under development. In its current form, it basically just provides a write-only interface to a ProcessTrace object.
    • Method Detail

      • startEvent

        void startEvent​(String aComponentName,
                        String aEventType,
                        String aDescription)
        Records the start of an event. The event will be ended when there is a corresponding call to endEvent(String,String,String) with the same component name and event type. The duration of the event will be automatically computed from the difference in time between the start and end.
        Parameters:
        aComponentName - name of the component generating the event
        aEventType - type of the event. Standard types are defined as constants on the ProcessTraceEvent interface, but any string may be used.
        aDescription - description of the event
      • endEvent

        void endEvent​(String aComponentName,
                      String aEventType,
                      String aResultMessage)
        Records the end of an event. The event is identified by the component name and type. If there is no open event that matches those values, a UIMA_IllegalStateException will be thrown.
        Parameters:
        aComponentName - name of the component generating the event
        aEventType - type of the event. Standard types are defined as constants on the ProcessTraceEvent interface, but any string may be used.
        aResultMessage - describes the result of the event
        Throws:
        UIMA_IllegalStateException - if there is no open event matching the aComponentName and aEventType arguments.
      • addEvent

        void addEvent​(String aResourceName,
                      String aType,
                      String aDescription,
                      int aDuration,
                      String aResultMsg)
        Records a completed event with the specified parameters.
        Parameters:
        aResourceName - name of the component generating the event
        aType - type of the event. Standard types are defined as constants on the ProcessTraceEvent interface, but any string may be used.
        aDescription - description of the event
        aDuration - duration of the event in milliseconds
        aResultMsg - result message of event
