A more generic way to refer to other methods are the $ZObjMethod and $ZObjClassMethod
functions, which are for instance and class methods, respectively. These provide a mechanism
for referring to packages, classes, and methods programmatically.
21.5 i% Syntax
When you instantiate a class with a persistent property, Caché creates what is called an
instance variable, which holds the property's value. When you set or refer to a property value,
Caché invokes what are called “Get” and “Set” accessor methods, which ultimately refer
to the instance variable. The accessor methods have names of the form Get
and Set, where is the name of property being accessed.
For example, if a class contains an LName property of type %String:
Property LName As %String;
then displaying the property's value for a particular instance
> Write MyClass.Up.LName
Pepperidge
actually goes through the MyClass.Up.LNameGet accessor method to get the value from
the property's instance variable.
Similarly, the typical call to set a property's value:
>Set MyClass.Up.LName = "Blutarsky"
actually invokes the MyClass.Up.LNameSet method, passing in the new value to set the
value of the instance variable and, thereby, that of LName.
