Methods

 

	Name	Description
	Bind(T1, T2)	Invokes a function on this maybe value that itself yields a maybe.
	Do(T)(Maybe(T), Action(T))	If contans a value executes an Action(T) delegate over it.
	Do(T1, T2)(Maybe(Tuple(T1, T2)), Action(T1, T2))	If contans a value executes an Action(T1, T2) delegate over it.
	FromJust(T)	Extracts the element out of a Just(T) and returns a default value if its argument is Nothing(T).
	FromJustOrFail(T)	Extracts the element out of a Just(T) and throws an error if its argument is Nothing(T).
	GetValueOrDefault(T)	If contains a values returns it, otherwise returns noneValue.
	IsJust(T)	Returns true iffits argument is of the form Just(T).
	IsNothing(T)	Returns true iffits argument is of the form Nothing(T).
	Map(T1, T2)	Transforms this maybe value by using a specified mapping function.
	MapValueOrDefault(T1, T2)	If contains a values executes a mapping function over it, otherwise returns noneValue.
	Match(T)(Maybe(T), Action(T), Action)	Provides pattern matching using Action delegates.
	Match(T1, T2)(Maybe(Tuple(T1, T2)), Action(T1, T2), Action)	Provides pattern matching using Action delegates over maybe with tupled wrapped value.
	MatchJust(T1, T2)	Matches a value returning true and tupled value itself via two output parameters.
	Select(TSource, TResult)	Map operation compatible with Linq.
	SelectMany(TSource, TValue, TResult)	Bind operation compatible with Linq.
	ToEnumerable(T)	Returns an empty list when given Nothing(T) or a singleton list when given a Just(T).
	ToMaybe(T)	Equivalent to monadic Return(T)(T) operation. Builds a Just(T) value in case value is different from its default.
