Carbonado in the pores that are common in carbonados, they may have been introduced after carbonado formation. Inclusions of other minerals, rare or nearly absent in the Earth's crust, are found at least partly incorporated in diamond, not just in pores: among such other minerals are those with compositions of Si, SiC, and Fe‑Ni. No distinctive high-pressure minerals, including the hexagonal carbon polymorph, lonsdaleite, have been found as inclusions in carbonados, although such inclusions might be expected if carbonados formed by meteorite impact. Isotope studies have yielded further clues to carbonado origin. The carbon isotope value is very low (little carbon‑13
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
