1. Overload¶

public static IObservable<T> Defer<T>(Func<Task<IObservable<T>>> observableFactory)

View source

Summary: Creates a signal whose source is produced asynchronously for each subscription.

Type parameters

Name	Description
`T`	The value type.

Parameters

Name	Type	Description
`observableFactory`	Func>>	The asynchronous factory that creates the source signal for a subscription.

Returns: IObservable -- A signal that subscribes to the factory-produced source for each observer.

Exceptions

Type	Condition
System.ArgumentNullException	`observableFactory` is `null`.

2. Overload¶

public static IObservable<T> Defer<T>(Func<CancellationToken, Task<IObservable<T>>> observableFactory)

View source

Summary: Creates a signal whose source is produced asynchronously for each subscription.

Type parameters

Name	Description
`T`	The value type.

Parameters

Name	Type	Description
`observableFactory`	Func>>	The asynchronous factory that creates the source signal for a subscription.

Returns: IObservable -- A signal that subscribes to the factory-produced source for each observer.

Exceptions

Type	Condition
System.ArgumentNullException	`observableFactory` is `null`.

3. Overload¶

public static IObservable<T> Defer<T>(Func<IObservable<T>> observableFactory)

View source

Summary: Creates a signal whose source is produced separately for each subscription.

Type parameters

Name	Description
`T`	The value type.

Parameters

Name	Type	Description
`observableFactory`	Func>	The factory that creates the source signal for a subscription.

Returns: IObservable -- A signal that subscribes to the factory-produced source for each observer.

Exceptions

Type	Condition
System.ArgumentNullException	`observableFactory` is `null`.
