## 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.
|
||
