Bind Variable AccessorsBind Variable Accessors
For both anonymous and named bind variables (including special bind variables) it is also possible to append an "accessor" reference that will allow further access into the object specified as the bind variable.

For instance:
SELECT :_allobjs.size
FROM   java.lang.Object
will return the number of objects matching the query.

Bind variable accessors follow the same rules as normal accessors.
