Describe availability of the paired portable C++ implementation.

Developer documentation: this item describes internal implementation details.

Declaration

 contract = portableImplementationContract(self)

Parameters

• self observing system to inspect

Returns

• contract scalar portable implementation contract

Discussion

The base class is intentionally unavailable. A supported concrete observing system overrides this method with a versioned, data-only contract. The portable runtime still requires an exact source-level C++ registration.
