Raw pointers are banned in new code unless absolutely necessary. Instead, use managed pointer types to prevent null pointer dereferences, dangling pointers, and memory safety issues.
Use the appropriate managed pointer type based on ownership semantics:
SP<T> (shared pointer) for shared ownershipUP<T> (unique pointer) for exclusive ownershipWP<T> (weak pointer) for non-owning referencesExample from the codebase:
// Bad - raw pointer prone to null dereferences
CExtWorkspaceHandleV1* workspace;
SSessionLockSurface* touchFocusLockSurface;
CXxColorManagementSurfaceV4* m_pCMSurface = nullptr;
// Good - managed pointers prevent null issues
SP<CExtWorkspaceHandleV1> workspace;
WP<SSessionLockSurface> touchFocusLockSurface;
WP<CXxColorManagementSurfaceV4> m_pCMSurface;
For protocol implementations, prefer UP<> for resource ownership while allowing WP<> references to it. This pattern ensures proper lifetime management and prevents accessing freed memory.
