Specifying the POPSPEC Parameter for Non-Collection Properties
For a literal property that is not a collection, use one of the following variations:
-
POPSPEC="MethodName()" — In this case, Populate() invokes the class method MethodName*( of the %PopulateUtilsOpens in a new tab class.
-
POPSPEC=".MethodName()" — In this case, Populate() invokes the instance method MethodName() of the instance that is being generated.
-
POPSPEC="##class(ClassName).MethodName()" — In this case, Populate() invokes the class method MethodName() of the ClassName class.
For example:
Property HomeCity As %String(POPSPEC = "City()");
If you need to pass a string value as an argument to the given method, double the starting and closing quotation marks around that string. For example:
Property PName As %String(POPSPEC = "Name(""F"")");
Also, you can append a string to the value returned by the specified method. For example:
Property JrName As %String(POPSPEC = "Name()_"" jr."" ");
Notice that it is necessary to double the starting and closing quotation marks around that string. It is not possible to prepend a string, because the POPSPEC is assumed to start with a method.
Also see Specifying the POPSPEC Parameter via an SQL Table for a different approach.
