Three types of package are available:

+ +
Packaged modifiable buffer descriptor

This is an +object of type TPckgBuf and is a modifiable buffer descriptor. +The class is templated; the template parameter defines the type of object +that this descriptor can contain.

For example, a package descriptor +of type TPckgBuf<TExample> is a modifiable buffer descriptor +that only contains objects of type TExample.

The package +class also allows functions to be called on the contained class.

+ +
+
Packaged non-modifiable pointer descriptor

This +is an object of type TPckgC and is a non-modifiable pointer +descriptor. The class is templated; the template parameter defines the type +of object that this descriptor can represent.

For example, a package +descriptor of type TPckgC<TExample> is a non- modifiable +pointer descriptor that only represents objects of type TExample.

The +package class also allows functions to be called on the contained class.
