Interface RegistryEntryList<T>

All Superinterfaces:
Iterable<RegistryEntry<T>>
All Known Implementing Classes:
RegistryEntryList.Direct, RegistryEntryList.ListBacked, RegistryEntryList.Named
public interface RegistryEntryList<T> extends Iterable<RegistryEntry<T>>
A registry entry list is an immutable list of registry entries. This, is either a direct reference to each item, or a reference to a tag. A tag is a way to dynamically define a list of registered values. Anything registered in a registry can be tagged, and each registry holds a list of tags it recognizes.

This can be iterated directly (i.e. for (RegistryEntry<T> entry : entries). Note that this does not implement Collection.
