22*cc02d7e2SAndroid Build Coastguard Worker  * A "proxy" class that simply forwards values, completion, and errors from its input writer to its
23*cc02d7e2SAndroid Build Coastguard Worker  * writeable.
24*cc02d7e2SAndroid Build Coastguard Worker  * It is useful as a superclass for pipes that act as a transformation of their
25*cc02d7e2SAndroid Build Coastguard Worker  * input writer, and for classes that represent objects with input and
26*cc02d7e2SAndroid Build Coastguard Worker  * output sequences of values, like an RPC.
27*cc02d7e2SAndroid Build Coastguard Worker  *
28*cc02d7e2SAndroid Build Coastguard Worker  * Thread-safety: the methods of this class are thread safe.
