XMLFormattable
Returns a xml representation of the object of the implementing class.
Most implementation should use the following code to ensure consistent data with the
other toXML
method:
return this.toXML(new StringBuffer()).toString();

DiffXEvent
The default weight should be 1.

DiffXEvent
This method is intended for use by algorithms, optimisers and loaders in order to adjust the importance of an event.
setWeight
in interface DiffXEvent
weight
- The weight of this event.DiffXEvent.setWeight(int)
