public interface Enhanced
Interface implemented by a persistent class via bytecode enhancement.
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 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(); } } }
