| persistent-object | Base class for all persistent classes. If this class is not inherited by a persistent class then ... |
|---|
| oid | Life time unique identifier of the instance which can be remembered and may be used the load the instance later. Initargs::oid; Accessors:oid-of; Type:(or
null
oid). |
|---|---|
| persistent | True means the instance is known to be persistent, false means the instance is known to be transient, unbound means the state is not yet determined. Actually, in the latter case slot-value-using-class will automatically determine whether the instance is in the database or not. Therefore reading the persistent slot will always return either true or false. Initargs::persistent; Accessors:persistent-p; Type:boolean. |
| transaction | A reference to the transaction to which this instance is currently attached to or nil. Initargs::transaction; Accessors:transaction-of. |
| transaction-event | :created means the instance was created in the current transaction, :modified means the instance was not created but modified in the current transaction. :deleted means the instance was already present at the very beginning but got deleted in the current transaction. Initargs::transaction-event; Accessors:transaction-event-of; Type:(member
nil
created
modified
deleted). |

|---|---|
| empty! | Removes all items from the container and returns nil. |
| empty-p | Returns t if there are no items in the container. |
| insert-item | Adds item to the container |
| iterate-items | Applies function to each item in the persistent container. |
| list-of | Returns a non lazy list of items present in the persistent collection. |
| search-for-item | Hunt for the item in the container. Key and Test are as in member. |
| setflist-of | Returns a non lazy list of items present in the persistent collection. |
| size | Returns the number of items currently in the container. |
