Module Function Ruby Example

It now makes sense to introduce another language feature in ruby.

Module function ruby example.

The ruby include statement simply makes a reference to a named module. Examples to implement of ruby modules. So this behavior isn t that different from the instance method behavior we saw in the first example. Instead it makes a reference from the class to the included module.

The modulo function in ruby returns the modulo value of a number by another number. And modules unlike classes therefore do not have a. We can explain the below example in the. In ruby a module can be used as logical entity.

Using the require method. However modules can not be instantiated. In ruby modules are somewhat similar to classes. Consider the following module.

Second a ruby include does not simply copy the module s instance methods into the class. This is an example where we are creating a module and inside this module we are defining a few methods and a constant and then we are directly accessing these methods and constants with the name of the modules. One feature of ruby that makes it such a good fit for frameworks like rails is that you can execute arbitrary code inside class and module. You can embed a module in a class.

If used with no arguments subsequently defined methods become module. To embed a module in a class you use the include statement in the class syntax include modulename if a module is defined in a separate file then it is required to include that file using require statement before embedding module in a class. If that module is in a separate file you must use require to drag that file in before using include. The instance method versions are made private.

Module functions are copies of the original and so may be changed independently. They are things that hold methods just like classes do. The function takes number1 and number2 whose modulo is returned. Remember classes and modules are treated as objects in ruby.

Inside of a class or module definition. I e it is not possible to create objects from a module. Below are the examples of ruby modules. It groups methods at a module level without using the mixin facility for example the base64 module i highly recommend you to read the source.
