Error on empty input

[fatihpense]

I add this issue from Alejandro's comment on the blog post: https://blogs.sap.com/2016/07/03/an-open-source-abap-json-library-zclmdpjson/comment-page-1/#comment-543786

Hello again, Fatih Pense another issue and quick fix for method ZCL_MDP_JSON_DESERIALIZER=>DESERIALIZE (you could document it on github):

On trying to deserialize an empty JSON string, you get the following short dump:

STRING_OFFSET_TOO_LARGE CX_SY_RANGE_OUT_OF_BOUNDS Illegal access to a string (offset too large)

I solved it by adding the following correction to raise the same exception used for other errors:

method deserialize.


    data : l_jsonnode type ref to zcl_mdp_json_node.

* correction >>>>>>>>    (FIX A.BINDI 2020.12.11)
  if json is initial.
    raise exception type zcx_mdp_json_invalid.
  endif.
* correction <<<<<<<<    (FIX A.BINDI 2020.12.11)

    deserialize_node(
  exporting
    json = json
    offset_before = 0
  importing
    jsonnode = l_jsonnode ) .

    node = l_jsonnode.

endmethod.
