DeferredRegistry

DeferredRegistry is an implementation of Bukkit’s Registry interface.

A DeferredRegistry stays mutable until initialize() is called, after which all mutation will silently fail.

In BuildMC-Core DeferredRegistry is used to store objects, that others may wish to modify, but cannot be changed after initialization. Internal DeferredRegistrys are typically exposed in the BuildMcAPI via RegistriesHolder. During BuildMcRegistryEvent, plugins can modify an exposed DeferredRegistry, after which it will be initialized and the plugin finishes loading.
