Parameters

• parameter SQLENABLED = 1;

Properties

• property Attribute as %CacheString;
Attribute
• property Name as %CacheString [ Required ];
Specifies the name of the StorageData definition. This name must be a valid storage member name and must not conflict with any other StorageData names.
• property Structure as %CacheString [ InitialExpression = "listnode" ];
Specifies how the data is stored into a global node.
• property Subscript as %CacheString;
Subscript
• relationship Values as %Dictionary.StorageDataValueDefinition [ Inverse = parent,Cardinality = children ];
Value
• relationship parent as %Dictionary.StorageDefinition [ Inverse = Data,Cardinality = parent ];
Pointer to the containing parent object

Methods

• classmethod %Exists(oid As %ObjectIdentity) as %Boolean
Checks to see if the object identified by the OID oid exists in the extent.

Returns %Boolean TRUE if it exists, FALSE if it does not.

• classmethod %LockId(id As %String, shared As %Boolean = 0, timeout As %Integer) as %Status
Obtain an exclusive or shared lock on the object identified by id. The type of lock obtained is determined by shared. This method is normally generated by the storage class for persistent classes using %Library.CacheStorage or %Library.CacheSQLStorage.
• classmethod %UnlockId(id As %String, shared As %Boolean = 0, immediate As %Boolean = 0) as %Status
Release an exclusive or shared lock on the object identified by id. The type of lock released is determined by shared. If this method is not overridden then the default implementation returns an error. This method is normally generated by the storage class for persistent classes using %Library.CacheStorage or %Library.CacheSQLStorage.
• classmethod StructureIsValid(val As %String) as %Status
• classmethod parentOnDelete(id As %String, concurrency As %Integer) as %Status

Indices

• index (IDKEY on Name) [IdKey];

Triggers

• trigger OnDelete (AFTER event DELETE)
• trigger OnInsertUpdate (BEFORE event INSERT/UPDATE)
