Create structure and Classes
Create Structure
創(chuàng)建structure結(jié)構(gòu)如下
Create Class ZCL_CONATINER
ZCL_CONATINER用于存儲(chǔ)UIBB的DATA匆笤，其沒(méi)有method甘邀，只有一個(gè)attribute布轿。
Create Class ZCL_CONNECTOR
ZCL_CONNECTOR 作為wire schema的connector class腐魂，在interface中引入IF_FPM_CONNECTOR，IF_FPM_CONNECTOR_DEF蒙挑，IF_FPM_CONNECTOR_RUN确镊，在attribute中引入MO_CONTAINER與 MV_PORT_TYPE，在方法中添加 CLASS_CONSTRUCTOR。
實(shí)現(xiàn)相應(yīng)的方法
METHOD if_fpm_connector_run~get_output.
* Set container data as output
ro_output = mo_container.
ENDMETHOD.
METHOD if_fpm_connector_run~is_create_allowed.
* Entity creation is not possible
rv_allowed = abap_false.
ENDMETHOD.
METHOD if_fpm_connector_def~initialize.
* Set value to port type and wire label
mv_port_type = iv_port_type.
if_fpm_connector_def~mv_wire_label = 'Identity'. " hard code just for example, you can create text element
ENDMETHOD.
METHOD if_fpm_connector_def~set_input.
* set input data to container
mo_container ?= io_input.
ENDMETHOD.
METHOD class_constructor.
* It's generally to set 'FBI' as sv_namespace
if_fpm_connector~sv_namespace = 'FBI'.
ENDMETHOD.
Create Class ZCL_INITIAL_FORM_UIBB_FDR
創(chuàng)建ZCL_INITIAL_FORM_UIBB_FDR作為 initial page 中 FORM GUIBB 的 feeder class根蟹，引入接口IF_FPM_GUIBB脓杉，IF_FPM_GUIBB_FORM，IF_FPM_FEEDER_MODEL简逮，添加 attributes MO_DATA球散，MS_OBJECT_KEY
實(shí)現(xiàn)相應(yīng)的方法
METHOD if_fpm_feeder_model~get_inport_key.
* Provide the inport object key
GET REFERENCE OF ms_object_key INTO rr_object_key.
ENDMETHOD.
METHOD if_fpm_feeder_model~get_namespace.
* Get namespace, the namespace is what you set in connector class zcl_fpm_connector
rv_namespace = 'FBI'.
ENDMETHOD.
METHOD if_fpm_feeder_model~get_outports.
* Maintain outports
DATA: ls_outport TYPE if_fpm_feeder_model=>ty_s_port.
CLEAR et_outport.
GET REFERENCE OF ms_object_key INTO ls_outport-object_key.
ls_outport-type = if_fpm_feeder_model=>cs_port_type-selection.
ls_outport-identifier = 'SE'.
ls_outport-description = 'Selection'.
INSERT ls_outport INTO TABLE et_outport.
GET REFERENCE OF ms_object_key INTO ls_outport-object_key.
ls_outport-type = if_fpm_feeder_model=>cs_port_type-collection.
ls_outport-identifier = 'CO'.
ls_outport-description = 'Collection'.
INSERT ls_outport INTO TABLE et_outport.
ENDMETHOD.
METHOD if_fpm_feeder_model~get_outport_data.
* Create container instance
IF mo_data IS NOT BOUND.
CREATE OBJECT mo_data.
ENDIF.
ro_data ?= mo_data.
ENDMETHOD.
METHOD if_fpm_guibb_form~flush.
* This method can achieve the new value in UI
DATA: ls_change_log TYPE fpmgb_s_changelog,
lv_name TYPE name_komp.
FIELD-SYMBOLS: <fs_userid> TYPE /bobf/conf_key.
* Field name in screen
lv_name = 'USERID'.
* set the new value to container
READ TABLE it_change_log INTO ls_change_log WITH KEY name = lv_name.
IF sy-subrc = 0.
ASSIGN ls_change_log-new_value->* TO <fs_userid>.
mo_data->mo_container = <fs_userid>.
ENDIF.
ENDMETHOD.
METHOD if_fpm_guibb_form~get_definition.
* This method is mandatory for feeder class
* For all variants
eo_field_catalog ?= cl_abap_typedescr=>describe_by_name( 'ZFPM_STR' )."structure name
ENDMETHOD.
METHOD if_fpm_guibb~initialize.
* Create instance for container
CREATE OBJECT mo_data.
ENDMETHOD.
Create Class ZCL_MAIN_FORM_UIBB_FDR
與前面類似，創(chuàng)建ZCL_MAIN_FORM_UIBB_FDR作為 main page 中 FORM GUIBB 的 feeder class散庶，引入接口IF_FPM_GUIBB蕉堰，IF_FPM_GUIBB_FORM，IF_FPM_FEEDER_MODEL悲龟，添加 attributes MO_DATA屋讶，MS_OBJECT_KEY，MO_CONNECTOR
實(shí)現(xiàn)相應(yīng)的方法
METHOD if_fpm_feeder_model~get_inport_key.
* Get inport key
GET REFERENCE OF ms_object_key INTO rr_object_key.
ENDMETHOD.
METHOD if_fpm_feeder_model~get_namespace.
rv_namespace = 'FBI'.
ENDMETHOD.
METHOD if_fpm_feeder_model~set_connector.
* Set connector
mo_connector ?= io_connector.
ENDMETHOD.
METHOD if_fpm_guibb_form~get_data.
* Set data to UI
DATA: lv_name TYPE name_komp.
FIELD-SYMBOLS: <fs_userid> TYPE /bobf/conf_key.
* Get data from connector
mo_data ?= mo_connector->if_fpm_connector_run~get_output( ).
* Set data to field 'USERID'
ASSIGN COMPONENT 'USERID' OF STRUCTURE cs_data TO <fs_userid>.
<fs_userid> = mo_data->mo_container.
* Set data changed flag
ev_data_changed = abap_true.
ENDMETHOD.
METHOD if_fpm_guibb_form~get_definition.
* This method is mandatory
* For all variants
eo_field_catalog ?= cl_abap_typedescr=>describe_by_name( 'ZFPM_STR' ).
ENDMETHOD.
