Specifies that an annotation type is a stereotype.

In many systems, use of architectural patterns produces a set of recurring bean roles. A stereotype allows a framework developer to identify such a role and declare some common metadata for beans with that role in a central place.

A bean may declare zero, one or multiple stereotypes, by applying the stereotype annotation to the bean class or producer method or field.

A stereotype encapsulates any combination of:

• a default scope, and
• a set of interceptor bindings.

The default scope of a stereotype is defined by annotating the stereotype with a scope type. A stereotype may declare at most one scope. If a bean explicitly declares a scope, any default scopes declared by its stereotypes are ignored.

@RequestScoped
@Stereotype
@Target(TYPE)
@Retention(RUNTIME)
public @interface Action {
}

The interceptor bindings of a stereotype are defined by annotating the stereotype with the interceptor binding types. A stereotype may declare zero, one or multiple interceptor bindings. An interceptor binding declared by a stereotype is inherited by any bean that declares that stereotype.

@RequestScoped
@Secure
@Transactional
@Stereotype
@Target(TYPE)
@Retention(RUNTIME)
public @interface Action {
}

A stereotype may also specify that:

• all beans with the stereotype have defaulted bean EL names, or that
• all beans with the stereotype are alternatives.

A stereotype may declare an empty @Named annotation, which specifies that every bean with the stereotype has a defaulted name when a name is not explicitly specified by the bean.

@RequestScoped
@Named
@Secure
@Transactional
@Stereotype
@Target(TYPE)
@Retention(RUNTIME)
public @interface Action {
}

A stereotype may declare an @Alternative annotation, which specifies that every bean with the stereotype is an alternative.

@Alternative
@Stereotype
@Target(TYPE)
@Retention(RUNTIME)
public @interface Mock {
}

A stereotype may declare other stereotypes. Stereotype declarations are transitive. A stereotype declared by a second stereotype is inherited by all beans and other stereotypes that declare the second stereotype.
