SAS/AF Software: Class Dictionary

Using the SAS Catalog Entry Class

You can create a SAS Catalog Entry object. When you instantiate a SAS Catalog Entry object, only the object identifier is created. You then add information about a SAS catalog entry to the object. This step is referred to as initializing the object. To initialize a SAS Catalog Entry object, use the _setup method. This example initializes the SAS Catalog Entry object, CATENTOBJ, to SASUSER.PROFILE.PASSIST.SLIST:

cateclass=loadclass('sashelp.fsp.catentry.
                     class');
catentobj=instance(cateclass);
call send (catentobj, '_setup_', 'sasuser.
           profile.passist.slist');

Note: Unless an example includes LOADCLASS, INSTANCE, and _setup, the example assumes that you have instantiated a SAS Catalog Entry object and initialized it using these statements. [cautionend]

If you list the contents of CATENTOBJ, you see:

( _class=2663
  DESC='SAS Catentry Class'
  FULLNAME='SASUSER.PROFILE.PASSIST.SLIST'
  DESCRIPTION='User profile'
  LIBRARY=<invalid list id>[0]
  CATALOG=<invalid list id>[0]
  ATTRIBUTES=<invalid list id>[0]
  )[2687]

LIBRARY, CATALOG, and ATTRIBUTES are list identifiers. Notice that at this point, they have a value of 0, an invalid list identifier. The reason is that these values are not initialized by _setup. Use _getLibrary, _getCatalog, and _getAttributes to initialize these lists.
