Methods

private classmethod %DeleteData(id As %String, concurrency As %Integer) as %Status [ Language = objectscript ]
Inherited description: This method is normally generated by the storage class for persistent classes using %Storage.Persistent or %Storage.SQL. Persistent classes using some other storage class, such as %Library.CustomStorage must override this method.
private method %LoadData(id As %String) as %Status [ Language = objectscript ]
Inherited description: %LoadData() - loads an object from storage. This method is implemented by the storage class.
private method %OnNew(initvalue As %String) as %Status [ Language = objectscript ]
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.

private method %OnValidateObject() as %Status [ Language = objectscript ]
Inherited description: This callback method is invoked by the %ValidateObject() method to provide notification that the current object is being validated.

If this method returns an error then %ValidateObject() will fail.

private method %SaveData(id As %String) as %Status [ Language = objectscript ]
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.
method AttributesGet() as %RawString [ Language = objectscript ]
method AttributesSet(newvalue As %RawString) as %Status [ Language = objectscript ]
