For the same term in general usage, see stereotype.

In computing, a stereotype is a concept in the Unified Modeling Language, where it is used to encapsulate behaviors. Thus, a stereotype is used as a vehicle for communicating software requirements and designs, and lacks the negative connotation present in general usage.

Denote stereotypes with double angle brackets. In a class diagram example, stereotypes can be used to describe method behaviors, such as <<constructor>> and <<gettor>>.
