Types of package

Describes the three types of package descriptors.

Three types of package are available:

• a packaged modifiable buffer descriptor

• a packaged non-modifiable pointer descriptor

• a packaged modifiable pointer descriptor

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.

Packaged modifiable pointer descriptor

This is an object of type TPckg and is a 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 TPckg<TExample> is a modifiable pointer descriptor that only represents objects of type TExample .

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