Detailed Description

template<class Interface>
class icomp::TReferenceMember< Interface >

Pointer to referenced component object.

Don't use direct this class, use macros I_REF and I_ASSIGN instead.

Thread-Safety:

This class uses double-checked locking with std::atomic for thread-safe lazy initialization. The pattern is safe because:

• m_isInitialized is atomic with sequential consistency (default memory order)
• m_interfacePtr is atomic
• Once m_isInitialized is true, no further modifications occur to the cached data
• The mutex protects the initialization phase
