TAndRClasses: typical 'T' and 'R' type classes

Found in: epoc32ex\Basics\TAndRClasses

TAndRClasses shows a typical ‘T’ class and a typical ‘R’ class.

The ‘T’ type is a value type, owning no external object.

The ‘R’ type is a resource type; typically this is proxy for an object owned elsewhere. In practice, the 'R' type is a handle to a resource owned and managed by the Kernel.

In this example, the ‘R’ class derives from the standard timer class RTimer.

Run the example either under WINS or on the ARMI platform.

• RTimer : asynchronous timer service

• TCleanupItem : general cleanup item

• CleanupStack : a cleanup stack

• TRequestStatus : asynchronous request status
