NOTE

This is not maintained. I worked on this a long time ago and decided to open source it for posterity.

This approach works, but my gut feeling is that this is something that should be done via backpressure. I might try this again in the future as such.


A normalizing operator for RxJava Observables.

An operator that normalizes the flow of data through an {@link Observable} stream in such a way that it will only emit a maximum of once per specified time window. If the previous emission was longer before than the specified window, it will emit immediately.

This is similar to debounce and various throttle operators, except that this will not drop or skip any emissions. All emissions are queued if necessary.

Usage

Java:

myBananaObservable
  ...
  .lift(new OperatorNormalize<Banana>(1, TimeUnit.SECONDS)
  ...

Kotlin:

// Extension directly applied to Observable
myObservable
  ...
  .normalize(1, TimeUnit.SECONDS)
  ...
