        int getMicrosecondsCount()
        Returns:
        the high resolution timer value stored at the time this tracepoint was generated.

      • getFormattedTime

        String getFormattedTime()
        Returns:
        the time in the format ????????

        the thread identifier of the thread that produced this TracePoint.

      • getComponent

        String getComponent()
        Returns:
        the name of the component that produced this TracePoint. A tracepoint is identified by componentName](containerCompName)].numericID, for example, comp1.14, or comp1(comp2).12.

      • getContainerComponent

        String getContainerComponent()
        Returns:
        the name of the container component that produced the current TracePoint, or null if the TracePoint did not have a container component. A tracepoint is identified by componentName](containerCompName)].numericID, for example, comp1.14, or comp1(comp2).12.

      • getFormattedParameters

        String getFormattedParameters()
        Returns:
        a String containing the parameters formatted and interpolated into the TracePoint's formatting template.

      • getParameterFormattingTemplate

        String getParameterFormattingTemplate()
        Returns:
        a String containing the formatting template for this TracePoint.

      • getParameters

        Object[] getParameters()
        Returns:
        an array of objects, with one object per parameter generated by this TracePoint. Returns null if the TracePoint has no parameters, or if parameters were not recorded for this TracePoint.

      • getGroups

        String[] getGroups()
        Returns:
        a list of groups to which this TracePoint belongs, or none if it doesn't belong to any.
