targets Stream targets' ip addresses and ports.

Constructor Summary

RTPConnectorOutputStream(DatagramSocket socket)

Constructor Detail

RTPConnectorOutputStream

public RTPConnectorOutputStream(DatagramSocket socket)

Initializes a new RTPConnectorOutputStream which is to send packet data out through a specific UDP socket.

Parameters:

socket - the UDP socket used to send packet data out

Method Detail

addTarget

public void addTarget(InetAddress remoteAddr,
                      int remotePort)

Add a target to stream targets list

Parameters:

remoteAddr - target ip address

remotePort - target port

createRawPacket

protected RawPacket createRawPacket(byte[] buffer,
                                    int offset,
                                    int length)

Creates a new RawPacket from a specific byte[] buffer in order to have this instance send its packet data through its write(byte[], int, int) method. Allows extenders to intercept the packet data and possibly filter and/or modify it.

Parameters:

buffer - the packet data to be sent to the targets of this instance

offset - the offset of the packet data in buffer

length - the length of the packet data in buffer

Returns:

a new RawPacket containing the packet data of the specified byte[] buffer or possibly its modification; null to ignore the packet data of the specified byte[] buffer and not send it to the targets of this instance through its write(byte[], int, int) method

removeTarget

public boolean removeTarget(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)
