Type Members

1.  class FilterEventStream[A] extends WritableEventStream[A] with SingleParentObservable[A, A] with InternalNextErrorObserver[A]

   This stream fires a subset of the events fired by its parent

   This stream fires a subset of the events fired by its parent

   This stream emits an error if the parent stream emits an error (Note: no filtering applied), or if passes throws

2.  class FoldLeftSignal[A, B] extends WritableSignal[B] with SingleParentObservable[A, B] with InternalTryObserver[A]

   Note: In folds, failure is often toxic to all subsequent events.

   Note: In folds, failure is often toxic to all subsequent events. You often can not satisfactorily recover from a failure downstream because you will not have access to previous non-failed state in fn Therefore, make sure to handle recoverable errors in fn.

3.  class MapEventStream[I, O] extends WritableEventStream[O] with SingleParentObservable[I, O] with InternalNextErrorObserver[I]

   This stream applies a project function to events fired by its parent and fires the resulting value

   This stream applies a project function to events fired by its parent and fires the resulting value

   This stream emits an error if the parent observable emits an error or if project throws

   If recover is defined and needs to be called, it can do the following: - Return Some(value) to make this stream emit value - Return None to make this stream ignore (swallow) this error - Not handle the error (meaning .isDefinedAt(error) must be false) to emit the original error

   If recover throws an exception, it will be wrapped in ErrorHandlingError and propagated.

4.  class MapSignal[I, O] extends WritableSignal[O] with SingleParentObservable[I, O] with InternalTryObserver[I]

   This signal emits an error if the parent observable emits an error or if project throws

   This signal emits an error if the parent observable emits an error or if project throws

   If recover is defined and needs to be called, it can do the following: - Return Some(value) to make this signal emit value - Return None to make this signal ignore (swallow) this error - Not handle the error (meaning .isDefinedAt(error) must be false) to emit the original error
