https://github.com/dhonza/JCOOL/wiki Wrapper class around a point (or input vector) array. This class is immutable making it threadsafe. It is not extendible because it has no public constructor. Creation is handled by a static factory method an ideal point for caching or hashcode precomputation. Added value:

• more abstraction
• default inplementations of equals + hashcode
• can be used in collections
• caching
