## ◆ handleMetadata()

virtual void nx::sdk::analytics::IDeviceAgent::IHandler0::handleMetadata | ( | IMetadataPacket * | metadataPacket | ) |
| pure virtual

Passes a metadata packet to the Server. It's worth to mention that passing a single metadata packet containing multiple metadata items with the same timestamp is preferred to passing multiple metadata packets with the same timestamp containing a single item. Although the latter will work correctly, it reduces the performance of the VMS Client. For example, if you have 10 objects detected on the same frame, it's better to send 1 packet with all the object metadata than 10 separate packets.
