Interface ComponentHolder

All Known Implementing Classes:
ItemStack
public interface ComponentHolder
An object that holds components. Note that this interface does not expose methods to modify the held components.

Component holders usually have "base" components and the overrides to the base (usually referred to as "changes"). The overrides may set additional components, modify the values from the base-provided default, or "unset"/remove base values. Methods in this interface expose the final value, after applying the changes.
