Detailed Description

For information on this class, see Working with Collections.

The <CLASS>ListOfObjects</CLASS> class represents a list of references to objects, each of which is associated with a numeric position in the list. The first element in the list is stored at position 1. The objects referred to must be registered. They can be either persistent objects or non-id objects.

Internally, a <CLASS>ListOfObjects</CLASS> object contains two lists: one for holding the OID values for the objects referred to (or their serialized state in the case of a list of non-id objects); and another for holding the OREF values for any objects that have been explicitly referred to, and hence "swizzled" into memory. Swizzling (loading an object into memory and generating an OREF value for it) happens automatically whenever the user refers to an object within the list. For example, if list is an <CLASS>ListOfObjects</CLASS> object containing a list of Doctor objects (that is a list of OID values for Doctor objects stored in the database) then the following code fragment will automatically load the Doctor object at location 7 in the list into memory and generate an OREF value referring to the in-memory version of the Doctor object. This OREF value can then be used to access the properties and methods of the Doctor object:

Set doc=list.GetAt(7) Write doc.Name

Alternatively, we could use cascading dot syntax:

Set name=list.GetAt(7).Name

When the <CLASS>ListOfObjects</CLASS> object is closed (removed from memory) it will close (call Close on) all the references it has swizzled into memory. These classes can be used 'standalone' to store a collection.
