Specifies the cardinality of a relationship property. The Cardinality keyword is required for relationship properties. It is ignored by non-relationship properties.
Specifies that this property is the identity for this class. Identity properties can be set in new objects only and the default is set by incrementing a counter.
Specifies the name of the inverse side of a relationship. That is, the name of the corresponding relationship property in the related class. The inverse property must exist in the related class and have the correct Cardinality value. The Inverse keyword is required for relationship properties. It is ignored by non-relationship properties.
In the case of a persistent class, specifies the column name used to identify the property in its SQL projection. By default, the SQL column name is the same as the property name.
Inherited description: 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.
Inherited description: This callback method is invoked by the %New() method to
provide notification that a new instance of an object is being created.
If this method returns an error then the object will not be created.
It is passed the arguments provided in the %New call.
When customizing this method, override the arguments with whatever variables and types you expect to receive from %New().
For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:
Method %OnNew(dob as %Date = "", name as %Name = "") as %Status
If instead of returning a %Status code this returns an oref and this oref is a subclass of the current
class then this oref will be the one returned to the caller of %New method.
Inherited description: %SaveData() - saves an object to disk, checks uniqueness and referential
integrity constraints, and maintains index structures. This method is
implemented by the storage class.
Inherited description: 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.
