Abstrakt

This GEM adds support of standard OOP entities such as Abstract Class (and Interface in TODO) on class declaration level. It means, that your interpreter will raise exceptions in case if your class, which inherits from the Abstract class, does not implement defined abstract methods.

Described behaviour imitates Java compilation errors.

Installation

Add this line to your application's Gemfile:

gem'abstrakt'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install abstrakt

Usage

Don't forget to require 'abstrakt' in your source code!

Abstract class declaration

To define your own abstract class, you need to extend Abstract::Builder module in your abstract class declaration:

classMyAbstraktClassextendAbstrakt::Builderend

Now you can declare your abstract methods, by using the Abstrakt DSL words:

  • abstract :method_name or public_abstract :method_name to define abstract public method;
  • protected_abstract :method_name to define protected abstract method;
  • private_abstract :method_name to define private abstract method;

As any other abstract class, your class can also define non-abstract methods implementations, as well as class singleton methods as usual.

Example:

classAbstractStringInstrumentextendAbstrakt::Builderabstract:playpublic_abstract:tuneprotected_abstract:strings_numberprivate_abstract:weightdefpresent!puts"I am a #{self.class} instrument with #{strings_number} strings!"endend

If you will try to create an instance of the abstract class, it will throw Abstrakt::Exceptions::InstantiationError exception.

Abstract class implementation declaration

While Java uses extends word for class inheritance, we will stick to the regular Ruby inheritance operator instead. So, for creating the class, which implements your abstract class, you simply inherit from it and declare all abstract methods in your implementation!

Implementation example:

classGuitar < AbstractStringInstrumentdefinitialize(brand:,model:,weight:)@brand,@model,@weight=brand,model,weightenddefplay# this implements public abstract methodp'I am playing!'enddeftune# and this toop'Getting in EBGDAE tuning...'sleep2p'Done!'endprotecteddefstrings_number# this implements protected method6endprivateattr_reader:weight# and this is private oneend# Instantiation:lp=Guitar.newbrand: :gibson,model: :les_paul,weight: 5lp.present!

If you forgot to implement any of them, your intepreter will raise Abstrakt::Exceptions::InstanceMethodNotImplementedError exception.

Future development and TODO

Interfaces entities and interfaces inheritance functionality are also planned to be implemented as a separate module of Abstrakt GEM in future.

If you will try to create an instance of the abstract class, it will throw
Abstrakt::Exceptions::InstantiationError exception.
Abstract class implementation declaration
While Java uses extends word for class inheritance, we will stick to the
regular Ruby inheritance operator instead. So, for creating the class, which implements your abstract class, you simply inherit from it and declare all
abstract methods in your implementation!
Implementation example:
classGuitar < AbstractStringInstrumentdefinitialize(brand:,model:,weight:)@brand,@model,@weight=brand,model,weightenddefplay# this implements public abstract methodp'I am playing!'enddeftune# and this toop'Getting in EBGDAE tuning...'sleep2p'Done!'endprotecteddefstrings_number# this implements protected method6endprivateattr_reader:weight# and this is private oneend# Instantiation:lp=Guitar.newbrand: :gibson,model: :les_paul,weight: 5lp.present!
If you forgot to implement any of them, your intepreter will raise
Abstrakt::Exceptions::InstanceMethodNotImplementedError exception.
Future development and TODO
Interfaces entities and interfaces inheritance functionality are also planned to
be implemented as a separate module of Abstrakt GEM in future.

Abstrakt
This GEM adds support of standard OOP entities such as Abstract Class
(and Interface in TODO) on class declaration level. It means, that your
interpreter will raise exceptions in case if your class, which inherits from the
Abstract class, does not implement defined abstract methods.
Described behaviour imitates Java compilation errors.
Installation
Add this line to your application's Gemfile:
gem'abstrakt'
And then execute:
$ bundle install

Or install it yourself as:
$ gem install abstrakt

Usage
Don't forget to require 'abstrakt' in your source code!
Abstract class declaration
To define your own abstract class, you need to extend Abstract::Builder
module in your abstract class declaration:
classMyAbstraktClassextendAbstrakt::Builderend
Now you can declare your abstract methods, by using the Abstrakt DSL words:
  • abstract :method_name or public_abstract :method_name to define abstract
public method;
  • protected_abstract :method_name to define protected abstract method;
  • private_abstract :method_name to define private abstract method;
As any other abstract class, your class can also define non-abstract methods
implementations, as well as class singleton methods as usual.
Example:
classAbstractStringInstrumentextendAbstrakt::Builderabstract:playpublic_abstract:tuneprotected_abstract:strings_numberprivate_abstract:weightdefpresent!puts"I am a #{self.class} instrument with #{strings_number} strings!"endend
If you will try to create an instance of the abstract class, it will throw
Abstrakt::Exceptions::InstantiationError exception.
