[cdi-dev] [JBoss JIRA] (CDI-15) Relax @Target annotation for CDI Scopes and Qualifiers

Tue Sep 18 07:26:35 EDT 2012

    [ https://issues.jboss.org/browse/CDI-15?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719408#comment-12719408 ] 

Jozef Hartinger commented on CDI-15:
------------------------------------

Also, there may be cases where restricting a custom qualifier more than the spec requires @Target({METHOD, FIELD, PARAMETER, TYPE}) would be handy (e.g. FIELD and PARAMETER only for a qualifier marking special bean which can be injected but no other equally qualified bean can be produced).

> In some cases it may make sense to apply a scope or qualifier in a place that was not envisaged by the spec but that would be useful for a portable extension. 
> For example, the @Constructs extension described at
> http://www.seamframework.org/Weld/PortableExtensionsPackage#H-BeanDeclarationAtConstructorLevel
> is not possible because scopes and qualifiers can not be placed on constructors
