UPDATEFUNCTION()`¶

About UpdateFunction¶

Updates a CloudFront function.

You can update a function's code or the comment that describes the function. You cannot update a function's name.

To update a function, you provide the function's name and version (ETag value) along with the updated function code. To get the name and version, you can use ListFunctions and DescribeFunction.

IMPORTING¶

Required arguments:¶

`iv_name` `TYPE /AWS1/FNTFUNCTIONNAME` `/AWS1/FNTFUNCTIONNAME`¶

The name of the function that you are updating.

`iv_ifmatch` `TYPE /AWS1/FNTSTRING` `/AWS1/FNTSTRING`¶

The current version (ETag value) of the function that you are updating, which you can get using DescribeFunction.

`io_functionconfig` `TYPE REF TO /AWS1/CL_FNTFUNCTIONCONFIG` `/AWS1/CL_FNTFUNCTIONCONFIG`¶

Configuration information about the function.

`iv_functioncode` `TYPE /AWS1/FNTFUNCTIONBLOB` `/AWS1/FNTFUNCTIONBLOB`¶

The function code. For more information about writing a CloudFront function, see Writing function code for CloudFront Functions in the Amazon CloudFront Developer Guide.

RETURNING¶

`oo_output` `TYPE REF TO /aws1/cl_fntupdatefuncresult` `/AWS1/CL_FNTUPDATEFUNCRESULT`¶

Domain /AWS1/RT_ACCOUNT_ID

Primitive Type NUMC

Examples¶

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->updatefunction(
  io_functionconfig = new /aws1/cl_fntfunctionconfig(
    io_keyvaluestoreassociations = new /aws1/cl_fntkeyvalstoreassoc00(
      it_items = VALUE /aws1/cl_fntkeyvalstoreassoc01=>tt_keyvalstoreassociationlist(
        ( new /aws1/cl_fntkeyvalstoreassoc01( |string| ) )
      )
      iv_quantity = 123
    )
    iv_comment = |string|
    iv_runtime = |string|
  )
  iv_functioncode = '5347567362473873563239796247513D'
  iv_ifmatch = |string|
  iv_name = |string|
).

This is an example of reading all possible response values

  lo_functionsummary = lo_result->get_functionsummary( ).
  IF lo_functionsummary IS NOT INITIAL.
    lv_functionname = lo_functionsummary->get_name( ).
    lv_string = lo_functionsummary->get_status( ).
    lo_functionconfig = lo_functionsummary->get_functionconfig( ).
    IF lo_functionconfig IS NOT INITIAL.
      lv_string = lo_functionconfig->get_comment( ).
      lv_functionruntime = lo_functionconfig->get_runtime( ).

        LOOP AT lo_keyvaluestoreassociatio->get_items( ) into lo_row.

To update a function¶

Use the following command to update a function.

DATA(lo_result) = lo_client->updatefunction(
  io_functionconfig = new /aws1/cl_fntfunctionconfig(
    io_keyvaluestoreassociations = new /aws1/cl_fntkeyvalstoreassoc00(
      it_items = VALUE /aws1/cl_fntkeyvalstoreassoc01=>tt_keyvalstoreassociationlist(
        ( new /aws1/cl_fntkeyvalstoreassoc01( |arn:aws:cloudfront::123456789012:key-value-store/54947df8-0e9e-4471-a2f9-9af509fb5889| ) )
      )
      iv_quantity = 1
    )
    iv_comment = |my-changed-comment|
    iv_runtime = |cloudfront-js-2.0|
  )
  iv_functioncode = '66756E6374696F6E2D636F64652D6368616E6765642E6A73'
  iv_ifmatch = |ETVPDKIKX0DER|
  iv_name = |my-function-name|
).
