Description

PacketPeer is an abstraction and base class for packet-based protocols (such as UDP). It provides an API for sending and receiving packets both as raw data or variables. This makes it easy to transfer data over a protocol, without having to encode data as low level bytes or having to worry about network ordering.

Member Function Description

• int get_available_packet_count ( ) const

Return the number of packets currently available in the ring-buffer.

• RawArray get_packet ( ) const

Get a raw packet.

• Error get_packet_error ( ) const

Return the error state of the last packet received (via get_packet and get_var).

• Variant get_var ( ) const

Get a Variant.

• Error put_packet ( RawArray buffer )

Send a raw packet.

• int put_var ( Variant var )

Send a Variant as a packet.
