The classes, 51 * required to implement that functionality, should either be pre-defined 52 * or they can be downloaded from the certain URL, defined as CodeBase. 53 * 54 * The value types can have both public and private members. They support 55 * inheritance. Value types can also be abstract. 56 * 57 * For transferring the value type data via stream, it must implement either 58 * {@link CustomValue} or {@link StreamableValue}. 59 * 60 * @since 1.3 61 * 62 * @author Audrius Meskauskas, Lithuania (AudriusA@Bioinformatics.org) 63 */ 64 public interface ValueBase 65 extends IDLEntity 66 { 67 /** 68 * Get the truncatable repository ids. 69 * 70 * @return the array of repository ids, defining the base types, to that 71 * basic types this value base can be truncated. 72 */ _truncatable_ids()73 String[] _truncatable_ids(); 74 } 75
