◆ AddRelatedLayerName()

void AddRelatedLayerName ( const std::string layerName )

inline

Definition at line 345 of file Layer.hpp.

345 { m_RelatedLayerNames.emplace_back(layerName); }

◆ BackendSelectionHint()

void BackendSelectionHint ( Optional< BackendId > backend )

inlinefinalvirtual

Provide a hint for the optimizer as to which backend to prefer for this layer.

By providing a BackendSelectionHint there is no guarantee the input backend supports that layer. If IsLayerSupported() returns false with the backend hint, we default to calling IsLayerSupported() on the BackendPreferences vector. Use SetBackendId() if we can guarantee a backend supports that layer (IsLayerSupported returns true for a specific backend).
