Create an Interface in Raptor Flowchart

Introduction

In this tutorial, we will learn how to create an interface in the Raptor flowchart. An interface is a specification of abstract method signatures and constants. A class that implements the interface should provide implementations for the methods that are specified in the interface declaration.

An interface would only have method declarations. The actual implementation of the methods is up-to-the Class that implements the interface. This will allow more implementations and customization of the interface capabilities.

Interface example

For example, iAccount is an interface with methods deposit() and withdraw(). The interface doesn’t contain the method implementations.

SavingAccount is the class that implements the interface. SavingAccount class needs to provide the implementations for the methods deposit() and withdraw().

Many classes can implement the same interface. For example, another class called CheckingAccount can implement the iAccount interface but may provide different implementations for the methods in the interface.
