Mark the end of the code generation to replace the field reference.

Return an expression that can be used to access the target object, if !Modifier.isStatic(field().modifiers()). This variable refers to the target object available before the set or get of the field. If the field is static, this returns null.

Return an expression that can be used to access the field value. If getReferenceType()==GET, this variable must be set to the value returned by the reference. If getReferenceType()==SET, this variable contains the value to be stored by the reference.

After this call, the field reference will not be emitted. Instead, any sequence of Wrapper calls valid in a method body may be used to generate replacement code for the field reference. As an example, the following code would cause equivalent code to the original reference to be emitted, in the case of a non-static field:

Variable target = mf.getTargetObject() ;
Variable value = mf.getValue() ;
String name = field().name() ;

// For getReferenceType() == GET:
_assign( value, _field( target, name ) ) ;

// For getRerenceType() == SET:
_assign( _field( target, name ), value ) ;
