This is a helper class used by the service registry to collect dependencies from service starters.

Add a dependency

To add a dependency on a singleton object, use the corresponding class.

void add(@NotNull Class aService);

For dependencies that are not a singleton, you must include a filter to distinguish the individual instances of the class. Filters are a list of properties separated by commas, such as "key1=val1,key2=val2".

void add(@NotNull Class aService,
         @NotNull String aProperties);

An example is the specification of a namespace. Namespaces are not singletons. They can be distinguished by namespace ID:
