/**
* The Flowable class that implements the Reactive-Streams Pattern and offers factory methods,
* intermediate operators and the ability to consume reactive dataflows.
*
* Reactive-Streams operates with {@code Publisher}s which {@code Flowable} extends. Many operators
* therefore accept general {@code Publisher}s directly and allow direct interoperation with other
* Reactive-Streams implementations.
*
* The Flowable hosts the default buffer size of 128 elements for operators, accessible via {@link #bufferSize()},
* that can be overridden globally via the system parameter {@code rx2.buffer-size}. Most operators, however, have
* overloads that allow setting their internal buffer size explicitly.
*
* The documentation for this class makes use of marble diagrams. The following legend explains these diagrams:
*
* 
[]
*
* For more information see the ReactiveX
* documentation.

* @param
* the type of the items emitted by the Flowable
