      long getTimestampMillis()
      Returns:
      the GMT time in milliseconds at which this TracePoint was produced.

    • getMicrosecondsCount

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

    • getFormattedTime

      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.

      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.
