Carbonado supernova which occurred at least 3.8 billion years ago. After coalescing and drifting through outer space for about one and a half billion years, a large mass fell to earth as a meteorite approximately 2.3 billion years ago. It possibly fragmented during entry into the Earth's atmosphere and impacted in a region which would much later split into Brazil and the Central African Republic, the only two known locations of carbonado deposits. Carbonado Carbonado, commonly known as the "black diamond", is the toughest form of natural diamond. It is an impure form of polycrystalline diamond consisting of diamond, graphite, and
Carbonado (Java) as "Storables" in Carbonado, and they are defined by an interface or abstract class. Annotations are required to specify features which cannot be defined by Java interface alone. Every Storable must have an annotation describing the primary key of the entity. Carbonado Storables are not pure POJOs, and they must always extend the Storable superclass. By doing so, they gain access to various methods built into it. A Storable definition may also contain business logic, following the active record pattern. The actual implementation of the Storable is generated at runtime by Carbonado itself. The standard object methods of toString, equals
