Memoize Method

Memoize<T, TResult>(Func<T, TResult>, bool, IEqualityComparer<T>, Func<T, bool>)

Memoizes a function with a single parameter.

Declaration

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

Parameters

Type	Name	Description
Func<T, TResult>	func	The function to memoize.
bool	threadSafe	Indicates whether the memoization should be thread-safe.
IEqualityComparer<T>	comparer	The equality comparer to use for the input parameter.
Func<T, bool>	useCacheCondition	A function to determine if the result should be cached.

Returns

Type	Description
Func<T, TResult>	A memoized version of the function.

Type Parameters

Name	Description
T	The type of the input parameter.
TResult	The type of the result.

Memoize<T1, T2, TResult>(Func<T1, T2, TResult>, bool, Func<T1, T2, bool>)

Memoizes a function with two parameters.

Declaration

public static Func<T1, T2, TResult> Memoize<T1, T2, TResult>(this Func<T1, T2, TResult> func, bool threadSafe = false, Func<T1, T2, bool> useCacheCondition = null)

Parameters

Type	Name	Description
Func<T1, T2, TResult>	func	The function to memoize.
bool	threadSafe	Indicates whether the memoization should be thread-safe.
Func<T1, T2, bool>	useCacheCondition	A function to determine if the result should be cached.

Returns

Type	Description
Func<T1, T2, TResult>	A memoized version of the function.

Type Parameters

Name	Description
T1	The type of the first input parameter.
T2	The type of the second input parameter.
TResult	The type of the result.

Memoize<T1, T2, T3, TResult>(Func<T1, T2, T3, TResult>, bool)

Memoizes a function with three parameters.

Declaration

public static Func<T1, T2, T3, TResult> Memoize<T1, T2, T3, TResult>(this Func<T1, T2, T3, TResult> func, bool threadSafe = false)

Parameters

Type	Name	Description
Func<T1, T2, T3, TResult>	func	The function to memoize.
bool	threadSafe	Indicates whether the memoization should be thread-safe.

Returns

Type	Description
Func<T1, T2, T3, TResult>	A memoized version of the function.

Type Parameters

Name	Description
T1	The type of the first input parameter.
T2	The type of the second input parameter.
T3	The type of the third input parameter.
TResult	The type of the result.

Memoize<T1, T2, T3, TResult>(Func<T1, T2, T3, TResult>, bool, Func<T1, T2, T3, bool>)

Memoizes a function with three parameters, with a condition to determine if the result should be cached.

Declaration

public static Func<T1, T2, T3, TResult> Memoize<T1, T2, T3, TResult>(this Func<T1, T2, T3, TResult> func, bool threadSafe, Func<T1, T2, T3, bool> useCacheCondition)

Parameters

Type	Name	Description

bool	threadSafe	Indicates whether the memoization should be thread-safe.
Func<T1, T2, T3, bool>	useCacheCondition	A function to determine if the result should be cached.

Returns

Type	Description
Func<T1, T2, T3, TResult>	A memoized version of the function.

Type Parameters

Name	Description
T1	The type of the first input parameter.
T2	The type of the second input parameter.
