The packet class for network layer packets.
The packet class implements all functions required to build a network layer packet.
| Packet::Packet | ( | RoutedFrame | frame | ) |
Packet constructor. Constructor initializes basic members.
| packet_id | The ID of the packet. |
| packet_size | The size of the packet in bytes. |
| payload_data_type | Defines which type the payload is |
| source | The host name of the source |
| topic | The ROS topic name on which to publish |

| bool Packet::addFrame | ( | RoutedFrame | frame | ) |
Add the frame to the frame list of the packet, if the frame belongs to the packet. This method is needed to build up the packet on the receiver side. This method also checks if all frames are received and the packet is complete.
| frame | The frame that should be added |
