Class TypeRegistry

java.lang.Object
  dsto.dfc.databeans.TypeRegistry

public final class TypeRegistry
extends Object

The global registry of known data object types. Every type has a unique logical name, which does NOT necessarily correspond to its Java class name (eg "person", "key"). This class maintains a mapping from logical type names to TypeInfo objects that describe them.

This class also provides a mapping from Java class names to type names, allowing type info to be easily attached to POJO-based data objects (eg those derived from SimpleDataObject or JavaDataBean).
