Carbonado compared to carbon‑12, relative to typical diamonds). Carbonado exhibits strong luminescence (photoluminescence and cathodoluminescence) induced by nitrogen and by vacancies existing in the crystal lattice. Luminescence halos are present around radioactive inclusions, and it is suggested that the radiation damage occurred after formation of the carbonados, an observation perhaps pertinent to the radiation hypothesis listed below. The origin of carbonado is controversial. Some proposed hypotheses are as follows: None of these hypotheses for carbonado formation had come into wide acceptance in the scientific literature by 2008. Supporters of an extraterrestrial origin of carbonados propose that their material source was a
Carbonado (Java) and hashCode are also generated. This greatly simplifies the process of defining new entities, since no boilerplate code needs to be written. The process of loading a Storable by key starts by calling a factory method to create an uninitialized instance: Next, the key properties are set and load is called: A "Repository" is a gateway to the underlying database. A few core implementations are available, which include: In addition, composite Repositories exist which support simple replication and logging. All Repositories are created using a builder pattern. Each type of builder supports options specific to the Repository type. When a
