Wrapper (clothing)

The wrapper, lappa, or pagne is a colorful women's garment widely worn in West Africa. It has formal and informal versions and varies from simple draped clothing to fully tailored ensembles. The formality of the wrapper depends on the fabric used to create it.

West African kaftan/boubou

In West Africa, a kaftan or caftan is a pull-over woman's robe. In French, this robe is called a boubou, pronounced boo-boo. The boubou is the traditional female attire in many West African countries including Senegal, Mali and other countries. The boubou can be formal or informal attire. The formality of the kaftan depends upon the fabric used to create it.

Yoruba iro

In Yorubaland, Nigeria the wrapper is common, called an iro in the Yoruba language, pronounced i-roh. The wrapper is usually worn with a matching headscarf or head tie that is called a gele in Yoruba, pronounced geh-leh. A full wrapper ensemble consists of three garments, a blouse, called a buba, pronounced boo-bah the iro and a headscarf called a head tie in English and a gele in Yoruba. Traditional male attire is called a dashiki. A wrapper takes metres of quality fabric. White wrapper sets are worn during wedding ceremonies.

Adapter pattern

In software engineering, the adapter pattern is a software design pattern that allows the interface of an existing class to be used from another interface. It is often used to make existing classes work with others without modifying their source code.

Definition

An adapter helps two incompatible interfaces to work together. This is the real world definition for an adapter. Interfaces may be incompatible but the inner functionality should suit the need. The Adapter design pattern allows otherwise incompatible classes to work together by converting the interface of one class into an interface expected by the clients.

Structure

There are two types of adapter patterns:

Object Adapter pattern

In this type of adapter pattern, the adapter contains an instance of the class it wraps. In this situation, the adapter makes calls to the instance of the wrapped object.

Class Adapter pattern

This type of adapter uses multiple polymorphic interfaces implementing or inheriting both the interface that is expected and the interface that is pre-existing. It is typical for the expected interface to be created as a pure interface class, especially in languages such as Java (before jdk 1.8) that do not support multiple inheritance of classes.
