Syntax

C#

public static Func<TArg, TResult> Memoize<TArg, TResult>(
	this Func<TArg, TResult> func,
	IEqualityComparer<TArg> comparer,
	bool threadSafe = false
)

VB

	Optional threadSafe As Boolean = false
) As Func(Of TArg, TResult)

F#

[<ExtensionAttribute>]
static member Memoize : 
        func : Func<'TArg, 'TResult> * 
        comparer : IEqualityComparer<'TArg> * 
        ?threadSafe : bool

        let _threadSafe = defaultArg threadSafe false
*)
-> Func<'TArg, 'TResult> 

Parameters

 

func

Type: System.Func(TArg, TResult)
Function to memoize.

comparer

Type: System.Collections.Generic.IEqualityComparer(TArg)
Argument comparer

threadSafe (Optional)

Type: System.Boolean
If true - returns thread safe implementation

Type Parameters

 

TArg

Type of argument

TResult

Type of result

Return Value

Type: Func(TArg, TResult)
Memoized function

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Func(TArg, TResult). When you use instance method syntax to call this method, omit the first parameter.
