Interface DVector3C

All Known Implementing Classes:

DVector3

public interface DVector3C

Constant (unmodifiable) interface for dVector3. This returns an unmodifiable view of an (most likely) modifiable object. WARNING: This is only unmodifiable for the user. The class that returned this object may continue to modify it, these changes will also reflect in the 'unmodifiable view' that the user has. If the user requires a lasting immutable object, then the object needs to be cloned. This interface should only be implemented by DVector3. This allows efficient optimisation by the JVM, which is not possible with 2 (still somewhat efficient) or more (slow) sub-classes.
