code: protected int getPriorityFromTaintFrame(TaintFrame fact, int offset)
              throws DataflowAnalysisException {
          Taint parameterTaint = fact.getStackValue(offset);
          return getPriority(parameterTaint);
      }
docs: The default implementation of <code>getPriorityFromTaintFrame()</code> can be overridden if the detector must base its
  priority on multiple parameters or special conditions like constant values.
  
  By default, this method will call the <code>getPriority()</code> method with the parameter taint at the specified offset.
  
  @param fact The TaintFrame for the inspected instruction call.
  @param offset The offset of the checked parameter.
  @return Priorities interface values from 1 to 5 (Enum-like interface)
  @throws DataflowAnalysisException An exception thrown when the TaintFrame cannot be analyzed.
