toString

protected void toString(StringBuilder sb)

Description copied from class: Operation

A template method allows for additional information to be passed into the Operation.toString() method. So an Operation subclass can override this method and add additional debugging content. The default implementation does nothing so one is not forced to provide an empty implementation. It is a good practice always to call the super.toString(stringBuffer) when implementing this method to make sure that the super class can inject content if needed.

Overrides:

toString in class Operation

Parameters:

sb - the StringBuilder to add the debug info to.
