set

protected final <T> void set(Class<T> type,
                             Supplier<T> instanceSupplier)

Stores an instance of the given type.

Note that instances by default are considered final, and you are not allowed to update an instance of any given type manually. Uses resettable supplier to allow Registry to recreate given instances.

Type Parameters:
