Namespace: Cortex.Net.Core

Assembly: Cortex.Net.dll

Syntax

public static class DerivationExtensions : object

Methods

ClearObserving(IDerivation)

Cleans the Observing collection with notification of the observables.

Declaration

public static void ClearObserving(this IDerivation derivation)

Parameters

Type	Name	Description
IDerivation	derivation	The derivation to clean.

ShouldCompute(IDerivation)

Checks whether the IDerivationinstance should recompute itself.

Declaration

public static bool ShouldCompute(this IDerivation derivation)

Parameters

Type	Name	Description
IDerivation	derivation	The derivation.

Returns

Type	Description
System.Boolean	True when it needs to recompute, false otherwise.

Remarks

Might throw any other exception that a getter for IObservable will thow.

TrackDerivedFunction<T>(IDerivation, Func<T>)

Executes the provided function and tracks which observables are being accessed. The tracking information is stored on the IDerivation instance and the derivation is registered as observer of any of the accessed observables.

Declaration

public static (T, Exception) TrackDerivedFunction<T>(this IDerivation derivation, Func<T> function)

Parameters

Type	Name	Description
IDerivation	derivation	The derivation to use.
Func<T>	function	The function to execute.

Returns

Type	Description
System.ValueTuple<T, Exception>	A tuple containing the return value of the function or an Exception.

Type Parameters

Name	Description
T	The return type of the function.
