roInt, roFloat, roString

The intrinsic types roInt32, roFloat, and roString have an object and interface equivalent. These are useful in the following

situations:

• An object is needed instead of a typed value. For example, roList maintains a list of objects.

• If any object exposes the ifInt, ifFloat, or ifString interfaces, that object can be used in any expression that expects

a typed value. For example, an roTouchEvent can be used as an integer whose value is the userid of the

roTouchEvent.

Note: If "o" is an roInt, then these statements have the following effects:

o print o: Prints o.GetInt()

o i%=o: Assigns the integer i% the value of o.GetInt()

o k=o: Presumably k is typeOmatic, so it becomes another reference to the roInt o

o o=5: This is NOT the same as o.SetInt(5). Instead it releases o, changes the type of o to roINT32 (o is

typeOmatic), and assigns it to 5.

When a function that expects a BrightScript Object as a parameter is passed an int, float, or string, BrightScript

automatically creates the equivalent object.

Interfaces: ifInt, ifIntOps, ifFloat, ifString, ifStringOps

roInt contains the ifInt interface, which provides the following:

• GetInt() As Integer

• SetInt(value As Integer) As Void
