Class Replay

Namespace
Bonsai.Reactive
Assembly
Bonsai.Core.dll

Represents an expression builder that handles sharing of an observable sequence across the encapsulated workflow by eagerly replaying notifications.

Replay surfaces the observable sequence to the nested workflow using a ReplaySubject.

Marble diagram

ReplaySubject passes to each subscribed observer all the values from the source sequence, regardless of when the observer subscribes.

Any observers which subscribe late will immediately receive all values which were sent out between the time that ReplaySubject was created and the time that the observer subscribed to it. It is also possible to parameterize the ReplaySubject to throw away old values after a certain period of time, or after a specified buffer size is exceeded.
