Issue 3978: Some others ways to get an abstract storage type reference                                                                                                                                              (pss-ftf)
Source:  (, )
Nature: Enhancement
Severity: 
Summary: At this time, the PSDL mapping does not provide a way to create an object
and to directly get its reference. It means that if you want to have an
abstract storage type reference, you only have to solution :

- to use the _create operation from the storage home ( not very flexible )
- to find an storage type thanks to a find_ref_by_xxx from the abstract
storage home

I think that the "factory" mapping should be changed :

Currently : ( PSS spec, p 56 )

  factory create( accno );

  // it's like
  // Account create( in string accno )

After changes :

 factory create( accno );
<pre>
 // it's like
 // Account create( in string accno );
 // ref<Account> create_ref( in string accno );
</pre>
Moreover, the catalog currently provides : StorageObject find_by_pid( byte
[] pid );

It should be very useful to provide another method : StorageObjectRef
find_ref_by_pid( byte [] pid );

Resolution: accepted
Revised Text: Change the Java mapping for ref<> to be a pid (i.e. byte[]).

NATURE : Enhancement

We intensively use the PSS ( with OpenORB - www.openorb.orb - ) to
provide a
high flexibility for the OpenORB Services. To be able to use several
connectors without any changes into the source code, we need to use
abstract
descriptions.

At this time, the PSDL mapping does not provide a way to create an
object
and to directly get its reference. It means that if you want to have
an
abstract storage type reference, you only have to solution :

- to use the _create operation from the storage home ( not very
  flexible )
- to find an storage type thanks to a find_ref_by_xxx from the
  abstract
storage home

I think that the "factory" mapping should be changed :

Currently : ( PSS spec, p 56 )

  factory create( accno );

  // it's like
  // Account create( in string accno )

After changes :

 factory create( accno );

 // it's like
 // Account create( in string accno );
 // ref<Account> create_ref( in string accno );

Moreover, the catalog currently provides : StorageObject find_by_pid(
byte
[] pid );

It should be very useful to provide another method : StorageObjectRef
find_ref_by_pid( byte [] pid );
