Implementing /IWFND/IF_MGW_BOP_MAP_GSTREAM — Inbound Mapping

Get Stream inbound mapping method /IWFND/IF_MGW_BOP_MAP_GSTREAM~MAP_INBOUND is provided with:

  • Action Name

  • Action parameters

  • BOP DO

  • Table of Processed BOP DOs

  • Table of Processed Backend Data – Backend Data is filled with data from Custom Backend Connectivity API

  • Response Entity Data reference

To implement inbound mapping interface method /IWFND/IF_MGW_BOP_MAP_GSTREAM~MAP_INBOUND for get stream, proceed as follows:

  1. Map the input keys to the BOP DO request.

    DATA: ls_key_tab TYPE LINE OF /iwcor/if_odata_types=>nvp_t.
  DATA: lo_bop_do  TYPE REF TO /iwfnd/cl_mgw_bop_fl_read_do.

* BOP DO Request
  DATA: ls_request TYPE /iwfnd/cl_mgw_bop_fl_read=>_params_request.

  lo_bop_do ?= io_bop_do.

* Loop over the key tab to get the list of entity keys
* Map them to the BOP DO request structure

  LOOP AT it_key_tab INTO ls_key_tab.
    CASE ls_key_tab-name.
      WHEN 'airlineid'.
        ls_request-airlineid = ls_key_tab-value.
      WHEN 'connectid'.
        ls_request-connectionid = ls_key_tab-value.
      WHEN 'flightdate'.
        ls_request-flightdate = ls_key_tab-value.
    ENDCASE.
  ENDLOOP.

  2. Set the BOP DO with BOP DO request structure.

    lo_bop_do->set_request( ls_request ).
Implementing /IWFND/IF_MGW_BOP_MAP_GSTREAM — Outbound Mapping

Get Stream outbound mapping method is provided with:

  • Request parameters for an entity

  • BOP DO

  • Table of processed BOP DOs

  • Table of processed backend data – Backend data is filled with data from Custom Backend Connectivity API

  • Reference to entity data – Entity data can be partially filled by previous mapping specialists

To implement inbound mapping interface method /IWFND/IF_MGW_BOP_MAP_GSTREAM~MAP_OUTBOUND for get stream, proceed as follows:

  1. Get the BOP response.

  2. Map the response (binary content, mime type) to the parameter ER_STREAM.

    Sample code

      DATA:   lo_bop_do         TYPE REF TO /iwfnd/cl_boprr_tea_edp_do,   
             ls_response       TYPE /iwfnd/cl_boprr_tea_edp=>_params_response,   
             lo_api            TYPE REF TO  if_mr_api,   
             lv_uri            TYPE         string.  
     DATA:   lo_exp           TYPE REF TO /iwfnd/cx_mgw_busi_exception.  
 
             lo_bop_do ?= io_bop_do.  
             lo_bop_do->get_response( IMPORTING es_response = ls_response ).  
             lo_api = cl_mime_repository_api=>get_api( i_prefix = ls_response-ev_url ).  
             lv_uri = '3_people_money.gif'.      
             lo_api->get( EXPORTING i_url       = lv_uri                   
                          IMPORTING e_content   = es_stream-value                                    
                                    e_mime_type = es_stream-mime_type ).
