> DM has great support for single-cardinality dependencies, allowing you to only declare the dependency as (volatile) field. For multiple-cardinality dependencies, no such support is present, forcing you to always manually implement this using callbacks.
> It would be great if I could declare multiple-cardinality dependencies like:
> {code}
> private volatile List<MyService> m_services;
> {code}
> and let DM manage the list for me.
> Note that you need some additional reflection mojo to obtain the actual collection type. An example of how this can work can be found in a utility class for Swagger in the Amdatu-Web project, see https://bitbucket.org/amdatu/amdatu-web/src/master/org.amdatu.web.rest/src/org/amdatu/web/rest/doc/swagger/SwaggerUtil.java?at=master#cl-304
