[Home] Type Microsoft.FSharp.Control.Lazy

The type of delayed computations. Use the values in the Lazy module to manipulate values of this type, and the notation 'lazy expr' to create values of this type.

Instance Members

Member	Description
member Force : unit -> 'a	Force the execution of this value and return its result. Same as Value. Mutual exclusion is used to prevent other threads also computing the value. If the value is re-forced during its own computation the `Undefined` exception is raised.
member IsDelayed : bool	Indicates if the lazy value has yet to be computed
member IsException : bool	Indicates if the lazy value is being computed or the computation raised an exception
member IsForced : bool	Indicates if the lazy value has been successfully computed
member SynchronizedForce : unit -> 'a	Same as Force
member UnsynchronizedForce : unit -> 'a	Same as Force, except no lock is taken.
member Value : 'a	Force the execution of this value and return its result. Same as Value. Mutual exclusion is used to prevent other threads also computing the value.

Static Members

Member	Description
member Create : (unit -> 'a) -> Lazy<'a>	Create a lazy computation that evaluates to the result of the given function when forced
member CreateFromValue : 'a -> Lazy<'a>	Create a lazy computation that evaluates to the given value when forced
