LISTLFTAGEXPRESSIONS()`¶

About ListLFTagExpressions¶

Returns the LF-Tag expressions in caller’s account filtered based on caller's permissions. Data Lake and read only admins implicitly can see all tag expressions in their account, else caller needs DESCRIBE permissions on tag expression.

IMPORTING¶

Optional arguments:¶

`iv_catalogid` `TYPE /AWS1/LKFCATALOGIDSTRING` `/AWS1/LKFCATALOGIDSTRING`¶

The identifier for the Data Catalog. By default, the account ID.

The maximum number of results to return.

`iv_nexttoken` `TYPE /AWS1/LKFTOKEN` `/AWS1/LKFTOKEN`¶

A continuation token, if this is not the first call to retrieve this list.

RETURNING¶

Syntax Example¶

This is an example of the syntax for calling the method. It includes every possible argument and initializes every possible value. The data provided is not necessarily semantically accurate (for example the value "string" may be provided for something that is intended to be an instance ID, or in some cases two arguments may be mutually exclusive). The syntax shows the ABAP syntax for creating the various data structures.

DATA(lo_result) = lo_client->listlftagexpressions(
  iv_catalogid = |string|
  iv_maxresults = 123
  iv_nexttoken = |string|
).

This is an example of reading all possible response values

lo_result = lo_result.
IF lo_result IS NOT INITIAL.
  LOOP AT lo_result->get_lftagexpressions( ) into lo_row.
    lo_row_1 = lo_row.
    IF lo_row_1 IS NOT INITIAL.
      lv_namestring = lo_row_1->get_name( ).
      lv_descriptionstring = lo_row_1->get_description( ).
      lv_catalogidstring = lo_row_1->get_catalogid( ).
      LOOP AT lo_row_1->get_expression( ) into lo_row_2.
        lo_row_3 = lo_row_2.
        IF lo_row_3 IS NOT INITIAL.
          lv_lftagkey = lo_row_3->get_tagkey( ).
          LOOP AT lo_row_3->get_tagvalues( ) into lo_row_4.
            lo_row_5 = lo_row_4.
            IF lo_row_5 IS NOT INITIAL.
              lv_lftagvalue = lo_row_5->get_value( ).
            ENDIF.
          ENDLOOP.
        ENDIF.
      ENDLOOP.
    ENDIF.
  ENDLOOP.
  lv_token = lo_result->get_nexttoken( ).
ENDIF.
