inet::UdpDatagram

sys::Obj
  inet::UdpDatagram

UdpDatagram is used to encapsulate the buffer of data and the IP address for sending and receiving UDP packets with a UdpSocket.

addr

public IpAddr addr

The IP address to send this packet to, or the address we received this packet from. Note this is a shared instance during receive and must be copied to a new memory location if you wish to keep it.

buf

public byte[] buf

The buffer of data to send (must never be null)

flowinfo

public int flowinfo

IPv6 address flow info

len

public int len

Number of bytes past buf+off to send or receive, after receive() specified the number of bytes actually read

off

public int off

Offset into buffer

port

public int port

The IP port for address to send or receive

scopeId

public int scopeId

IPv6 address scope ID

getSocketAddr

public void getSocketAddr(SocketAddr sockAddr)

Copy the datagram to the socket address (makes a deep copy of the host addr).

setSocketAddr

public void setSocketAddr(SocketAddr sockAddr)

Copy this address to the datagram (makes a shallow copy of the host addr).
