public class EnhancerPropertySetterAdapter
extends MethodVisitor

Adapter for property setter methods in persistence-enabled classes. This adapter processes the setXXX method and

Creates dnSetXXX with the same code as was present in setXXX
Changes setXXX to have the code below

When detachable this will be (CHECK_WRITE variant)

 void setZZZ(YYY zzz)
 {
     if (dnFlags != 0 && dnStateManager != null)
         dnStateManager.setStringField(this, 2, dnGetZZZ(), zzz);
     else
     {
         dnSetXXX(zzz);
         if (dnIsDetached() == true)
             ((BitSet) dnDetachedState[3]).set(2);
     }
 }

and when not detachable

 void setZZZ(YYY zzz)
 {
     if (aFlags > 0 && dnStateManager != null)
         dnStateManager.setObjectField(this, 2, dnGetZZZ(), zzz);
     dnSetXXX(zzz);
 }

There are other variants for MEDIATE_WRITE and NORMAL_WRITE. TODO Consider supporting the fluent-style of JavaBean setter method, which returns the instance of the class. This class will need updates for that.

                       int arg3,
                       Object[] arg4)
```
    Description copied from class: MethodVisitor
    Visits the current state of the local variables and operand stack elements. This method must(*) be called just before any instruction i that follows an unconditional branch instruction such as GOTO or THROW, that is the target of a jump instruction, or that starts an exception handler block. The visited types must describe the values of the local variables and of the operand stack elements just before i is executed.
    
    (*) this is mandatory only for classes whose version is greater than or equal to Opcodes.V1_6.
    
    The frames of a method must be given either in expanded form, or in compressed form (all frames must use the same format, i.e. you must not mix expanded and compressed frames within a single method):
    - In expanded form, all frames must have the F_NEW type.
    - In compressed form, frames are basically "deltas" from the state of the previous frame:
      
      Opcodes.F_SAME representing frame with exactly the same locals as the previous frame and with the empty stack.
      Opcodes.F_SAME1 representing frame with exactly the same locals as the previous frame and with single value on the stack ( nStack is 1 and stack[0] contains value for the type of the stack item).
      Opcodes.F_APPEND representing frame with current locals are the same as the locals in the previous frame, except that additional locals are defined (nLocal is 1, 2 or 3 and local elements contains values representing added types).
      Opcodes.F_CHOP representing frame with current locals are the same as the locals in the previous frame, except that the last 1-3 locals are absent and with the empty stack (nLocals is 1, 2 or 3).
      Opcodes.F_FULL representing complete frame data.
    In both cases the first frame, corresponding to the method's parameters and access flags, is implicit and must not be visited. Also, it is illegal to visit two or more frames for the same code location (i.e., at least one instruction must be visited between two calls to visitFrame).
    Overrides:
    
    visitFrame in class MethodVisitor
    
    Parameters:
    
    arg0 - the type of this stack map frame. Must be Opcodes.F_NEW for expanded frames, or Opcodes.F_FULL, Opcodes.F_APPEND, Opcodes.F_CHOP, Opcodes.F_SAME or Opcodes.F_APPEND, Opcodes.F_SAME1 for compressed frames.
    
    arg1 - the number of local variables in the visited frame.
    
    arg2 - the local variable types in this frame. This array must not be modified. Primitive types are represented by Opcodes.TOP, Opcodes.INTEGER, Opcodes.FLOAT, Opcodes.LONG, Opcodes.DOUBLE, Opcodes.NULL or Opcodes.UNINITIALIZED_THIS (long and double are represented by a single element). Reference types are represented by String objects (representing internal names), and uninitialized types by Label objects (this label designates the NEW instruction that created this uninitialized value).
    
    arg3 - the number of operand stack elements in the visited frame.
    
    arg4 - the operand stack types in this frame. This array must not be modified. Its content has the same format as the "local" array.
