Classes representing so-called hot sources, aka subjects, that implement a base reactive class and
the respective consumer type at once to allow forms of multicasting events to multiple
consumers as well as consuming another base reactive type of their kind.

Available subject classes with their respective base classes and consumer interfaces:



Subject type
Base class
Consumer interface

    
Subject 
 AsyncSubject 
 BehaviorSubject 
 PublishSubject 
 ReplaySubject 
 UnicastSubject 
    
Observable
    
Observer


    
SingleSubject
    
Single
    
SingleObserver


    
MaybeSubject
    
Maybe
    
MaybeObserver


    
CompletableSubject
    
Completable
    
CompletableObserver


 The backpressure-aware variants of the Subject class are called Processors and reside in the io.reactivex.processors package.
