Interface CommandRegistryWrapper<T>

All Known Implementing Classes:
CommandRegistryWrapper.Impl
public interface CommandRegistryWrapper<T>
A wrapper of a registry, used in command arguments.

The methods in this class in most cases perform the same as ones defined in Registry. However, subclasses may have slightly different behaviors to make it easier to handle user-passed arguments. For example, getEntryList(TagKey) may return an empty RegistryEntryList instead of Optional.empty().

A wrapper without any special behaviors can be created by calling {#link of(Registry)}.

    • getEntryList

      Optional<? extends RegistryEntryList<T>> getEntryList(TagKey<T> tag)
      Returns the entry list for the provided tag.

      Implementations have different behaviors for unrecognized tags. The default implementation returns Optional.empty(); however, the ones created by CommandRegistryAccess.createWrapper(net.minecraft.util.registry.RegistryKey<? extends net.minecraft.util.registry.Registry<T>>) can create and return a new entry list, or return an empty entry list.

      Returns:
      the entry list for the provided tag
