A value 044 * type is something between CORBA structure and CORBA object. Like CORBA 045 * object, it can have methods, supporting some IDL-defined interface. 046 * However, like structures, they are local and passed by value, 047 * not by IOR reference. 048 * 049 * Unlike CORBA objects, values are not connected to any ORB by 050 * default; they hanlde the implemented functionality locally. The classes, 051 * required to implement that functionality, should either be pre-defined 052 * or they can be downloaded from the certain URL, defined as CodeBase. 053 * 054 * The value types can have both public and private members. They support 055 * inheritance. Value types can also be abstract. 056 * 057 * For transferring the value type data via stream, it must implement either 058 * {@link CustomValue} or {@link StreamableValue}. 059 * 060 * @since 1.3 061 * 062 * @author Audrius Meskauskas, Lithuania (AudriusA@Bioinformatics.org) 063 */ 064public interface ValueBase 065 extends IDLEntity 066{ 067 /** 068 * Get the truncatable repository ids. 069 * 070 * @return the array of repository ids, defining the base types, to that 071 * basic types this value base can be truncated. 072 */ 073 String[] _truncatable_ids(); 074}
