public class Operations
extends Object

Convenience, type-safe, methods for applying some common operations on coverage objects. All methods wrap their arguments in a parameter value group and delegate the work to the processor's doOperation method. This convenience class do not brings any new functionalities, but brings type-safety when the operation is know at compile time. For operation unknown at compile time (e.g. for an operation selected by users in some widget), use the processor directly.
