Async Operators

The following operators are part of the distinct rxjava-async module. They are used to convert synchronous methods into Observables.

  • start( ) — create an Observable that emits the return value of a function
  • toAsync( ) or asyncAction( ) or asyncFunc( ) — convert a function or Action into an Observable that executes the function and emits its return value
  • startFuture( ) — convert a function that returns Future into an Observable that emits that Future's return value
  • deferFuture( ) — convert a Future that returns an Observable into an Observable, but do not attempt to get the Observable that the Future returns until a Subscriber subscribes
  • forEachFuture( ) — pass Subscriber methods to an Observable but also have it behave like a Future that blocks until it completes
  • fromAction( ) — convert an Action into an Observable that invokes the action and emits its result when a Subscriber subscribes
  • fromCallable( ) — convert a Callable into an Observable that invokes the callable and emits its result or exception when a Subscriber subscribes
  • fromRunnable( ) — convert a Runnable into an Observable that invokes the runable and emits its result when a Subscriber subscribes
  • runAsync( ) — returns a StoppableObservable that emits multiple actions as generated by a specified Action on a Scheduler
