Methods

OrElse<T1, T2>(IExecutor<T1, Optional<T2>>, IExecutable<T1, T2>)

Supplies a fallback executable when the source executor produces no value.

[Pure]
public static IExecutor<T1, T2> OrElse<T1, T2>(this IExecutor<T1, Optional<T2>> executor, IExecutable<T1, T2> fallback)

Parameters

executor IExecutor<T1, Optional<T2>>

Source optional executor.

fallback IExecutable<T1, T2>

Fallback executable.

Returns

IExecutor<T1, T2>

Executor producing either the original value or the fallback result.

Type Parameters

T1

T2

Exceptions

ArgumentNullException

fallback is null.

OrElse<T1, T2>(IExecutor<T1, Optional<T2>>, IExecutor<T1, T2>)

Supplies a fallback executor when the source executor produces no value.

[Pure]

T2

Exceptions

ArgumentNullException

fallback is null.

OrWhen<T>(IExecutor<Unit, Optional<T>>, Func<bool>, IExecutable<Unit, T>)

Adds a parameterless conditional fallback executable executed when the source executor produces no value.

[Pure]
public static IExecutor<Unit, Optional<T>> OrWhen<T>(this IExecutor<Unit, Optional<T>> executor, Func<bool> condition, IExecutable<Unit, T> executable)

Parameters

executor IExecutor<Unit, Optional<T>>

Source optional executor.

condition Func<bool>

Condition evaluated before running fallback logic.

executable IExecutable<Unit, T>

Executable to run when the condition is satisfied.

Returns

Executor producing the original or fallback optional result.

Type Parameters

T

Exceptions

ArgumentNullException

condition or executable is null.

OrWhen<T>(IExecutor<Unit, Optional<T>>, Func<bool>, IExecutor<Unit, Optional<T>>)

Adds a parameterless conditional fallback executed when the source executor produces no value and flattens an optional fallback result.
