Store all instance variables of an object into an array.

Namespace:  XSharp.RT
Assembly:  XSharp.RT (in XSharp.RT.dll) Version: 2.08
Syntax
 FUNCTION IvarList(
	oObject AS Object
) AS ARRAY
View Source

Parameters

oObject
Type: Object
The object containing the instance variable to store.

Return Value

Type: Array
An array of symbols containing the name of all instance variables and access methods of <oObject>.
Remarks
This conversion can offer you additional flexibility in manipulating data and can allow you to utilize powerful array functions, such as AEval() and AScan().  The scope throughout the function call is SELF.
Examples
This example uses IVarList() to store INSTANCE and EXPORT instance variables into an array.  It then prints the stored instance variables.  (Note that the password is not stored in the array because it is a protected instance variable.)
X#
CLASS Person
        EXPORT name
        INSTANCE grade
        PROTECT password
METHOD Init(tname, tgrade, tpassword) CLASS Person
        name := tname
        grade := tgrade
        password := tpassword
FUNCTION MakeArray() AS VOID
        LOCAL x AS OBJECT
        LOCAL a AS ARRAY
        x := Person{"Randal", "A", "123"}
        a := IVarList(x)
        // Print them
        FOR i := UPTO ALen(a)
                QOut(a[i])
        NEXT
                                                // NAME
                                                // GRADE
