IMPORTING¶

Required arguments:¶

`iv_functionname` `TYPE /AWS1/LMDFUNCTIONNAME` `/AWS1/LMDFUNCTIONNAME`¶

The name or ARN of the Lambda function.

Name formats

Function name - MyFunction.

Function ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction.

Partial ARN - 123456789012:function:MyFunction.

The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

`iv_name` `TYPE /AWS1/LMDALIAS` `/AWS1/LMDALIAS`¶

The name of the alias.

Optional arguments:¶

`iv_functionversion` `TYPE /AWS1/LMDVERSION` `/AWS1/LMDVERSION`¶

The function version that the alias invokes.

`iv_description` `TYPE /AWS1/LMDDESCRIPTION` `/AWS1/LMDDESCRIPTION`¶

A description of the alias.

`io_routingconfig` `TYPE REF TO /AWS1/CL_LMDALIASROUTINGCONF` `/AWS1/CL_LMDALIASROUTINGCONF`¶

The routing configuration of the alias.

`iv_revisionid` `TYPE /AWS1/LMDSTRING` `/AWS1/LMDSTRING`¶

Only update the alias if the revision ID matches the ID that's specified. Use this option to avoid modifying an alias that has changed since you last read it.

RETURNING¶

`oo_output` `TYPE REF TO /aws1/cl_lmdaliasconfiguration` `/AWS1/CL_LMDALIASCONFIGURATION`¶

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->updatealias(
  io_routingconfig = new /aws1/cl_lmdaliasroutingconf(
    it_additionalversionweights = VALUE /aws1/cl_lmdaddlvrsweights_w=>tt_additionalversionweights(
      (
        VALUE /aws1/cl_lmdaddlvrsweights_w=>ts_addlversionweights_maprow(
          key = |string|
          value = new /aws1/cl_lmdaddlvrsweights_w( |0.1| )
        )
      )
    )
  )
  iv_description = |string|
  iv_functionname = |string|
  iv_functionversion = |string|
  iv_name = |string|
  iv_revisionid = |string|
).

This is an example of reading all possible response values

lo_result = lo_result.
IF lo_result IS NOT INITIAL.
  lv_functionarn = lo_result->get_aliasarn( ).
  lv_alias = lo_result->get_name( ).
  lv_version = lo_result->get_functionversion( ).
  lv_description = lo_result->get_description( ).
  lo_aliasroutingconfigurati = lo_result->get_routingconfig( ).
  IF lo_aliasroutingconfigurati IS NOT INITIAL.
    LOOP AT lo_aliasroutingconfigurati->get_additionalversionweights( ) into ls_row.
      lv_key = ls_row-key.
      lo_value = ls_row-value.
      IF lo_value IS NOT INITIAL.
        lv_weight = lo_value->get_value( ).
      ENDIF.
    ENDLOOP.
  ENDIF.
  lv_string = lo_result->get_revisionid( ).
ENDIF.

To update a function alias¶

The following example updates the alias named BLUE to send 30% of traffic to version 2 and 70% to version 1.

DATA(lo_result) = lo_client->updatealias(
  io_routingconfig = new /aws1/cl_lmdaliasroutingconf(
    it_additionalversionweights = VALUE /aws1/cl_lmdaddlvrsweights_w=>tt_additionalversionweights(
      (
        VALUE /aws1/cl_lmdaddlvrsweights_w=>ts_addlversionweights_maprow(
          key = |1|
          value = new /aws1/cl_lmdaddlvrsweights_w( |0.7| )
        )
      )
    )
  )
  iv_functionname = |my-function|
  iv_functionversion = |2|
  iv_name = |BLUE|
).
