C++ Reactive Programming

Operators

An Operator is a function that applies on an Observable to produce a new Observable. In the process, the original Observable is not mutated  and can be considered  as  a pure function. We have already covered lot of Operators in our  sample programs that we have written. In Chapter 10, Creating Custom Operators in Rxcpp, we will learn how to create custom Operators which work on Observables. The fact that an Operator does not mutate an (input) Observable is the  reason why declarative scheduling works in the Rx programming model. Rx Operators can be categorized as follows:

• Creation Operators
• Transformation Operators
• Filtering Operators
• Combining Operators
• Error-handling Operators
• Utility Operators
• Boolean Operators
• Mathematical ...
