Detailed Description

This interface is currently retained as a future extension point: it defines the minimal API contract that a dynamically-loaded factory would expose.

Plugin contract:

• A shared library exports an extern "C" symbol named "GSystemDynamicFactory".
• That symbol is a function returning a GSystemDynamicFactory* and taking std::shared_ptr<GOptions> as argument.

The helper instantiate() locates the symbol using dlsym and invokes it.

Note

This header intentionally uses for external dynamic-link concepts.

Member Function Documentation

instantiate()

static GSystemDynamicFactory * GSystemDynamicFactory::instantiate ( const dlhandle h, std::shared_ptr< GOptions > g )

inlinestatic

Parameters

h	Dynamic library handle (dlopen-style).
g	Shared options/configuration instance.

Returns

Factory instance pointer, or nullptr if the symbol is missing.

The symbol must be named exactly "GSystemDynamicFactory" and must match the expected signature.

loadSystem()

virtual void GSystemDynamicFactory::loadSystem ( GSystem * s, int verbosity )

pure virtual

Parameters

s	Target system to populate.
verbosity	Verbosity level (factory-specific interpretation).
