Detailed Description

Adapter component providing standalone device state provider.

CDeviceStateProviderAdapterComp implements the Adapter Pattern to extract and expose the IDeviceStateProvider interface from an IDeviceController as a standalone component. This enables state tracking to be used independently of the full controller interface.

Purpose:

Decouples device state tracking from device control operations, enabling:

• State monitoring without controller access
• Independent state provider references
• Simplified dependency injection
• UI binding to state changes only

Key Features:

• Standalone Interface: Provides IDeviceStateProvider without full controller
• Change Forwarding: Propagates state change notifications from controller
• Automatic Binding: Connects to controller's state provider on creation
• Cleanup Handling: Properly unbinds on destruction

Component Configuration:

• DeviceController: Reference to IDeviceController whose state provider to adapt

Lifecycle:

• OnComponentCreated(): Binds to controller's state provider for change notifications
• OnComponentDestroyed(): Unbinds from controller's state provider

Usage Pattern:

// Obtain state provider adapter instance (via component system)
CDeviceStateProviderAdapterComp* pStateAdapter = // get from component system
 
// Component is configured with DeviceController reference
 
// Use as standalone state provider
IDeviceStateProvider* pStateProvider = pStateAdapter;
IDeviceStateProvider::DeviceState state = pStateProvider->GetDeviceState(deviceId);
 
// Register for state change notifications
class StateObserver : public imod::CSingleModelObserverBase
{
protected:
       void OnUpdate(const istd::IChangeable::ChangeSet& changeSet) override
       {
              int changeFlags = changeSet.GetFlags();
              if (changeFlags & IDeviceStateProvider::CF_STATE_CHANGED)
              {
                     // Update UI based on state change
              }
       }
};
