Usage
# register Class by class name
SimpleObjectCotainer.register(MyClass)
# then, you can get a instance
SimpleObjectContainer.get(MyClass) # => the instance of MyClass
# and always return *the same* instance
SimpleObjectContainer.get(MyClass).equal_to? SimpleObjectContaner.get(MyClass) # => true
# you can register Class with a symbol as a key
SimpleObjectContainer.register(:key, AnotherClass)
# and you can get a instance using the key
SimpleObjectContainer.get(:key) # => the instance of AnotherClass
# and always return *the same* instance
SimpleObjectContainer.get(:key).equal_to? SimpleObjectContaner.get(:key) # => true
# you can register a lambda which return a object you want
SimpleObjectContainer.register(:key, lambda{ SomeClass.new(parameters) })
# and you can get a instance which is returned by the lambda
SimpleObjectContainer.get(:key) # => the instance of SomeClass initialized with parameters
# and always return *the same* instance
SimpleObjectContainer.get(:key).equal_to? SimpleObjectContaner.get(:key) # => true
SimpleObjectContainer has singleton interface like avobe and object interface like bellow.
container = SimpleObjectCotainer.new
container.register(MyClass)
# you can use object interface by same way to singleton interface
container.get(MyClass) # => the instance of MyClass
# and always return *the same* instance
container.get(MyClass).equal_to? container.get(MyClass) # => true
another_container = SimpleObjectCotainer.new
another_container.register(MyClass)
container.get(MyClass).equal_to? another_container.get(MyClass) # => false
