Pre condition functions export

Question

I have another question.
I have tried to export pre conditions but have not succeed yet in exporting the Pre Condition functions.
The  jcs_describe.describe doesn't work with the following types 'PRE_CONDITION', 'PRECONDITION', 'FUNCTION', etc.
Since it is possible to export the object on the RWE, with right-click / export, we guess that it is somehow possible with PL SQL functions.
Can someone give me some clues about that ?
Thanks again for your help,
Regards,

Hi,
Preconditions are not described like chains, scripts etc. They are regular functions in the database, which can be described using standard database functions.
As an example (in the Redwood Shell):
set serveroutput on
spool [youroutputfile].sql
declare
  c clob;
begin
  c:= dbms_metadata.get_ddl ( 'FUNCTION', '[functionname]', '[functionowner]' );
  dbms_output.put_line ( c );
end;
spool off
set serveroutput off
This will give you the definition of your precondition function in a file (of course you need to replace the texts between \[\] with proper values applying to your environment.
You can put this in a single script, let's call it desc_function.sql and pass the owner and functionname as parameters. From the Redwood Shell, the call would look like this:
@desc_function [owner] [functionname]
The file desc_function.sql would contain the following text:
set serveroutput on
spool &1._&2..sql
declare
  c clob;
begin
  c:= dbms_metadata.get_ddl ( 'FUNCTION', '&2', '&1' );
  dbms_output.put_line ( c );
end;
spool off
set serveroutput off
Hope this helps you out.
Kind regards,
