Constructor Detail

PersistKeyBinding

public PersistKeyBinding(Catalog catalog,
                         String clsName,
                         boolean rawAccess)

Creates a key binding for a given key class.

PersistKeyBinding

PersistKeyBinding(Class cls,
                  String[] compositeFieldOrder)

Creates a key binding dynamically for use by PersistComparator. Formats are created from scratch rather than using a shared catalog.

Method Detail

bytesToObject

Object bytesToObject(byte[] bytes,
                     int offset,
                     int length)

Binds bytes to an object for use by PersistComparator as well as entryToObject.

readKey

static Object readKey(Format keyFormat,
                      Catalog catalog,
                      byte[] bytes,
                      int offset,
                      int length,
                      boolean rawAccess)

Binds bytes to an object for use by PersistComparator as well as entryToObject.
