OpaqueHolder_test Class Reference

Description

Test:

use the OpaqueHolder inline buffer to handle objects of a family of types through a common interface, without being forced to use heap storage or a custom allocator.

Todo:

this test doesn't cover automatic conversions and conversions using RTTI from the target objects, while OpaqueHolder.template get() would allow for such conversions. This is similar to Ticket #141, and actually based on the same code as variant.hpp (access-casted.hpp)

checkHandling()

void checkHandling ( TestList &  objs )

inlineprivate

Test:

cover the basic situations of object handling, especially copy operations and re-assignments

checkSpecialSubclass()

void checkSpecialSubclass ( )

inlineprivate

Test:

OpaqueHolder with additional storage for subclass.

When a subclass requires more storage than the base class or Interface, we need to create a custom OpaqueHolder, specifying the actually necessary storage. Such a custom OpaqueHolder behaves exactly like the standard variant, but there is protection against accidentally using a standard variant to hold an instance of the larger subclass.

Test:

Moreover, if the concrete class has a custom operator bool(), it will be invoked automatically from OpaqueHolder's operator bool()
