Member Function Documentation

synchronized void com::sleepycat::bind::serial::StoredClassCatalog::close (   )  throws DatabaseException [inline]

Close a catalog database and release any cached resources. Implements com::sleepycat::bind::serial::ClassCatalog. Definition at line 127 of file StoredClassCatalog.java. Referenced by collections::ship::tuple::SampleDatabase::close(), collections::ship::sentity::SampleDatabase::close(), collections::ship::marshal::SampleDatabase::close(), collections::ship::index::SampleDatabase::close(), collections::ship::factory::SampleDatabase::close(), collections::ship::entity::SampleDatabase::close(), and collections::ship::basic::SampleDatabase::close().

synchronized ObjectStreamClass com::sleepycat::bind::serial::StoredClassCatalog::getClassFormat (  byte[]  classID  )  throws DatabaseException, ClassNotFoundException [inline]

Return the ObjectStreamClass for the given class ID. This may or may not be the current class format, depending on whether the class has changed since the class ID was generated. Parameters: classID  The class ID for which to return the class format. Returns: The class format for the given class ID, which may or may not represent the current version of the class. Implements com::sleepycat::bind::serial::ClassCatalog. Definition at line 147 of file StoredClassCatalog.java.

synchronized byte [] com::sleepycat::bind::serial::StoredClassCatalog::getClassID (  ObjectStreamClass  classFormat  )  throws DatabaseException, ClassNotFoundException [inline]

Return the class ID for the current version of the given class description. This is used for storing in serialization streams in place of a full class descriptor, since it is much more compact. To get back the ObjectStreamClass for a class ID, call getClassFormat(byte[]). This function causes a new class ID to be assigned if the class description has changed. Parameters: classDesc  The class description for which to return the class ID. Returns: The class ID for the current version of the class. Implements com::sleepycat::bind::serial::ClassCatalog.
