PolymorphicValue_test Class Reference

Description

Test:

build a bunch of PolymorphicValue objects.

Handle them like copyable value objects, without knowing the exact implementation type; moreover execute implementation internals only disclosed to the concrete subtype. Verify correctness through checksums.

Test:

internally, PolymorphicValue uses some metafunctions to pick a suitable code path, based on the presence of helper functions on the API of the embedded objects.

Default is no support by these objects, which then requires to use a more expensive implementation. Sometimes it's desirable to support cloning only (copy ctor), but no assignment after the fact. In this special case, a support API with only a cloneInto() member can be implemented, causing the PolymorphicValue container to raise an exception in case the copy operator is invoked.
