How enhancement implementations will be called in the Program???

Hi,

i have enhanced a method by implementing post exit .

so what it does is

1. it created a include ( ZERENH_EMAILPROP==============EIMP ), where ZERENH_EMAILPROP is my enhancement implementation name

2. it created a local class definition and implementation as well along with constructor and interface and its method ( one which i am enhancing )

*----------------------------------------------------------------------*
*       CLASS LCL_ZERENH_EMAILPROP DEFINITION
*----------------------------------------------------------------------*
*
*----------------------------------------------------------------------*
CLASS lcl_zerenh_emailprop DEFINITION.
  PUBLIC SECTION.
    CLASS-DATA obj TYPE REF TO lcl_zerenh_emailprop.
    DATA core_object TYPE REF TO cl_hrrcf_candidate .
 INTERFACES IPO_ZERENH_EMAILPROP.
    METHODS:
     constructor IMPORTING core_object
       TYPE REF TO cl_hrrcf_candidate OPTIONAL.
ENDCLASS.                    "LCL_ZERENH_EMAILPROP DEFINITION
*----------------------------------------------------------------------*
*       CLASS LCL_ZERENH_EMAILPROP IMPLEMENTATION
*----------------------------------------------------------------------*
*
*----------------------------------------------------------------------*
CLASS lcl_zerenh_emailprop IMPLEMENTATION.
  METHOD constructor.
    me->core_object = core_object.
  ENDMETHOD.                    "CONSTRUCTOR

  METHOD ipo_zerenh_emailprop~assign_application.
*"------------------------------------------------------------------------*
*" Declaration of POST-method, do not insert any comments here please!
*"
*"methods ASSIGN_APPLICATION
*"  importing
*"    !APPLICATION type ref to CL_HRRCF_CANDIDATE_APPLICATION
*"  raising
*"    CX_HRRCF_INFOTYPE_OPERATION .
*"------------------------------------------------------------------------*

    core_object->get_applications( ).
  ENDMETHOD.                    "IPO_ZERENH_EMAILPROP~ASSIGN_APPLICATION
ENDCLASS.

3. in enhancement implementation if i see tab called "Enhancement include" the following code is added

ENHANCEMENT 1 .
  data %_ZERENH_EMAILPROP type ref to OBJECT .
ENDENHANCEMENT.

ENHANCEMENT 2  .
INTERFACE IPO_ZERENH_EMAILPROP .

  methods ASSIGN_APPLICATION
    importing
      !APPLICATION type ref to CL_HRRCF_CANDIDATE_APPLICATION
    raising
      CX_HRRCF_INFOTYPE_OPERATION .
ENDINTERFACE.
INCLUDE ZERENH_EMAILPROP==============EIMP .
ENDENHANCEMENT.

ENHANCEMENT 3 .
IF ME->%_ZERENH_EMAILPROP IS INITIAL.
   CREATE OBJECT LCL_ZERENH_EMAILPROP=>OBJ
     EXPORTING CORE_OBJECT = ME.
ME->%_ZERENH_EMAILPROP ?= LCL_ZERENH_EMAILPROP=>OBJ .
ELSE.
LCL_ZERENH_EMAILPROP=>OBJ ?= ME->%_ZERENH_EMAILPROP .
ENDIF.
LCL_ZERENH_EMAILPROP=>OBJ->IPO_ZERENH_EMAILPROP~ASSIGN_APPLICATION( APPLICATION = APPLICATION   ).
ENDENHANCEMENT.

my question now is how SAP will call this enhancement implemenation runtime, how these statements are integrated to class so that it gets called???

Thanks,

Kranthi.
