IMPORTING¶

Required arguments:¶

`iv_name` `TYPE /AWS1/QLDLEDGERNAME` `/AWS1/QLDLEDGERNAME`¶

The name of the ledger.

`io_blockaddress` `TYPE REF TO /AWS1/CL_QLDVALUEHOLDER` `/AWS1/CL_QLDVALUEHOLDER`¶

The block location of the document revision to be verified. An address is an Amazon Ion structure that has two fields: strandId and sequenceNo.

For example: {strandId:"BlFTjlSXze9BIh1KOszcE3",sequenceNo:14}.

`iv_documentid` `TYPE /AWS1/QLDUNIQUEID` `/AWS1/QLDUNIQUEID`¶

The UUID (represented in Base62-encoded text) of the document to be verified.

Optional arguments:¶

`io_digesttipaddress` `TYPE REF TO /AWS1/CL_QLDVALUEHOLDER` `/AWS1/CL_QLDVALUEHOLDER`¶

The latest block location covered by the digest for which to request a proof. An address is an Amazon Ion structure that has two fields: strandId and sequenceNo.

For example: {strandId:"BlFTjlSXze9BIh1KOszcE3",sequenceNo:49}.

RETURNING¶

`oo_output` `TYPE REF TO /aws1/cl_qldgetrevisionrsp` `/AWS1/CL_QLDGETREVISIONRSP`¶

Domain /AWS1/RT_ACCOUNT_ID

Primitive Type NUMC

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->getrevision(
  io_blockaddress = new /aws1/cl_qldvalueholder( |string| )
  io_digesttipaddress = new /aws1/cl_qldvalueholder( |string| )
  iv_documentid = |string|
  iv_name = |string|
).

This is an example of reading all possible response values

lo_result = lo_result.
IF lo_result IS NOT INITIAL.
  lo_valueholder = lo_result->get_proof( ).
  IF lo_valueholder IS NOT INITIAL.
    lv_iontext = lo_valueholder->get_iontext( ).
  ENDIF.
  lo_valueholder = lo_result->get_revision( ).
  IF lo_valueholder IS NOT INITIAL.
    lv_iontext = lo_valueholder->get_iontext( ).
  ENDIF.
ENDIF.
