|---|---|
| persistent-direct-slot-definition | Class for persistent direct slot definitions. |
| persistent-effective-slot-definition | Class for persistent effective slot definitions. |
| always-checked-type | When type-check is :always then this type will be checked whenever a new value is set during the transaction. Initform:(compute-as*
nil
(compute-always-checked-type
-self-)), Initargs::always-checked-type; Accessors:always-checked-type-of; Type:list. |
|---|---|
| cache | All prefetched slots are cached slots but the opposite may not be true. When a cached slot is loaded it's value will be stored in the CLOS instance for fast subsequent read operations. Also whenever a cached slot is set the value will be remembered. The default cached slot semantics can be overriden on a per direct slot basis. Initargs::cache; Accessors:cache-p; Type:boolean. |
| index | True means the slot value will be indexed in the underlying RDBMS. Initargs::index; Accessors:index-p; Type:boolean. |
| initargs | Initargs::initargs; Accessors:slot-definition-initargs. |
| initfunction | Initargs::initfunction; Accessors:slot-definition-initfunction. |
| name | Initargs::name; Accessors:slot-definition-name. |
| prefetch | Prefetched slots are loaded from and stored into the database at once. A prefetched slot must be in a table which can be accessed using a where clause matching to the id of the instance thus it must be in a data table. The default prefetched slot semantics can be overriden on a per direct slot basis. Initargs::prefetch; Accessors:prefetch-p; Type:boolean. |
| type-check | On commit type check means that during the transaction the slot may have null and/or unbound value and the type check will be done when the transaction commits. Initargs::type-check; Accessors:type-check-of; Type:(member
always
on-commit). |
| unique | True means the slot value will be enforced to be unique among instances in the underlying RDBMS. Initargs::unique; Accessors:unique-p; Type:boolean. |
