METHOD supply .

DATA: ls_student  TYPE   ystr_person.

[MS1] ls_student-firstname = 'Ionescu'.

ls_student-lastname = 'Ana Maria'.

ls_student-dateofbirth = '19700309'.

APPEND ls_student TO lt_student.

ls_student-firstname = 'Marinescu'.

ls_student-lastname = 'Loredana'.

ls_student-dateofbirth = '19800523'.

APPEND ls_student TO lt_student.

[MS2] 

ENDMETHOD.

 [MS1]这是参照数据字典定义的，也可以参照node定义

*  DATA TYP_YES TYPE IF_V_VIEW=>ELEMENT_YPERSON.

*  DATA TYP_YES2 TYPE WD_THIS->ELEMENT_YPERSON.

其中V_VIEW为视图名字，YPERSON为node名字

 [MS2]绑定内表的数据，仅限于在node supplyfunction中使用这种绑定

参照node定义结构或者内表

wdctx_Student type string value `STUDENT`.

types:

Element_Student type YSTR_PERSON,

Elements_Student type

standard table of Element_Student

with default key.

这是针对node自动生成的数据

如果想定义内表，就写成：

DATA  LT_STUDENT TYPE WD_THIS->ELEMENTS_STUDENT.

获取子节点

DATA: lr_node TYPE REF TO if_wd_context_node,

lr_subnode TYPE REF TO if_wd_context_node.

DATA: lv_street TYPE string,

lv_number TYPE y_char,

lv_city TYPE string.

lr_subnode = lr_node->get_child_node( 'ADDRESS' ).

lr_subnode->get_attribute( EXPORTING name = 'STREET'

IMPORTING value = lv_street  ).

lr_subnode->get_attribute( EXPORTING name = 'NUMBER'

IMPORTING value = lv_number  ).

lr_subnode->get_attribute( EXPORTING name = 'CITY'

IMPORTING value = lv_city  ).

 

绑定子节点

DATA: lr_node TYPE REF TO if_wd_context_node,

lr_subnode TYPE REF TO if_wd_context_node,

ls_subnode TYPE if_view_name=>element_address.

lr_node = wd_context->get_child_node( 'FACULTY' ).

lr_subnode = lr_node->get_child_node( 'ADDRESS' ).

ls_subnode-street = 'Pforzheimer'.

ls_subnode-number = '106A'.

ls_subnode-city = 'Pforzheim'.

lr_subnode->set_static_attributes( ls_subnode ).

依次获得子节点
