Carbonado 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 amorphous carbon. It is found primarily in alluvial deposits in the Central African Republic and in Brazil. Its natural colour is black or dark grey, and it is more porous than other diamonds. Carbonado diamonds are typically pea-sized or larger porous aggregates of many tiny black crystals. The most characteristic carbonados have been found only in the Central African Republic and in Brazil, in neither place associated with kimberlite, the source of
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
