Constructor Detail

SocketOutputStream

public SocketOutputStream(java.net.DatagramSocket sckt)

Creates a new SocketOutputStream

Parameters:

socket - The datagram socket to adapt

sendAddress - The address to send packets to

sendPort - The port to send packets to

Method Detail

addTarget

public void addTarget(java.net.InetAddress remoteAddr,
                      int remotePort)

Add a target to stream targets list

Parameters:

remoteAddr - target ip address

remotePort - target port

removeTarget

public boolean removeTarget(java.net.InetAddress remoteAddr,
                            int remotePort)

Remove a target from stream targets list

Parameters:

remoteAddr - target ip address

remotePort - target port

Returns:

true if the target is in stream target list and can be removed false if not

removeTargets

public void removeTargets()

Remove all stream targets from this session.

write

public int write(byte[] buffer,
                 int offset,
                 int length)

Write a data buffer to all known remote targets. The methods loops over the vector of all known targets, builds, and sends datagram packet.

Specified by:

write in interface OutputDataStream

Parameters:

buffer - The byte array containing the data

offset - Offset into the byte array to get data from

length - Length in bytes of the data to send.

writeToRemote

public int writeToRemote(byte[] buffer,
                         int offset,
                         int length,
                         java.net.InetAddress remoteAddr,
                         int remotePort)

Write a data buffer to one specific remote target. The methods builds and sends datagram packet to a specified target. This is mostly used to send RTCP packet to a dedicated target, for example when removing a target.

Parameters:

buffer - The byte array containing the data

offset - Offset into the byte array to get data from

length - Length in bytes of the data to send

remoteAddr - The remote IP address of the target

remotePort - The port number of the target
