See Accessor for method documentation. EnhancedAccessor implements Accessor and forwards all calls to methods in the Enhanced class.

Each class that implements this interface (including its subclasses and superclasses except for Object) must also implement a static block that registers a prototype instance by calling EnhancedAccessor.registerPrototype. Other instances are created from the protype instance using Enhanced.bdbNewInstance .

static { EnhancedAccessor.registerPrototype(new Xxx()); }

An example of the generated code for reading and writing fields is shown below.

 private int f1;
 private String f2;
 private MyClass f3;
 public void bdbWriteNonKeyFields(EntityOutput output) {
 super.bdbWriteNonKeyFields(output);
 output.writeInt(f1);
 output.writeObject(f2, null);
 output.writeObject(f3, null);
 }
 public void bdbReadNonKeyFields(EntityInput input,
 int startField,
 int endField,
 int superLevel) {
 if (superLevel != 0) {
 super.bdbReadNonKeyFields(input, startField, endField,
 superLevel - 1);
 }
 if (superLevel <= 0) {
 switch (startField) {
 case 0:
 f1 = input.readInt();
 if (endField == 0) break;
 case 1:
 f2 = (String) input.readObject();
 if (endField == 1) break;
 case 2:
 f3 = (MyClass) input.readObject();
 }
 }
 }
