**Intent:** Twin pattern is a design pattern which provides a standard solution to simulate multiple
|
|
|
|
|
|
inheritance in java

**Applicability:** Use the Twin idiom when
|
|
|
|
|
|
|
|
|
|
|
|
* to simulate multiple inheritance in a language that does not support this feature.

|
|
|
|
* to avoid certain problems of multiple inheritance such as name clashes.
