3.x: Verify the use of base interfaces in operator inputs & lambdas by akarnokd · Pull Request #6858 · ReactiveX/RxJava (original) (raw)

This PR adds a test that verifies standard operator methods use base interfaces as their input and lambdas capable of returning base types do as well. Consequently, it fixes two declarations of Flowable.buffer having the wrong input type.

Basically, detect the following declarations:

// direct use of the class, should be Publisher public void method1(Flowable<?> f)

// lambda returns the class, should return a Publisher public void method2(Callable<Flowable<?>> c)

// The inner Publisher emits the class, should emit Publisher public void method3(Supplier<Publisher<Flowable<?>>> c)

// Direct use of the class as array type, should be Publisher[] public void method4(Flowable<?>[] array)

// Lambda returns an array of the class, should return Publisher[] public void method5(Callable<Flowable<?>[]> c)

// The inner Publisher emits an array of the class, should emit Publisher[] public void method6(Callable<Publisher<Flowable<?>[]>> c)
