About Function Library¶
The Backendless Codeless system promotes the concept of logic re-use through the Function Library. Any reusable logic can be implemented as functions. Each function has a name, a list of input parameters and an an optional return value. Once a function's is implemented, it is represented by a block in the Custom Functions category. The block can be used in any other Codeless logic in the application such as API services, API event handlers, timers or other functions.
