org.ice4j.socket.TurnDatagramPacketFilter

All Implemented Interfaces:

DatagramPacketFilter

public class TurnDatagramPacketFilter
extends StunDatagramPacketFilter

Implements a DatagramPacketFilter which accepts DatagramPackets which represent TURN messages defined in RFC 5766 "Traversal Using Relays around NAT (TURN): Relay Extensions to Session Traversal Utilities for NAT (STUN)" and which are part of the communication with a specific TURN server. TurnDatagramPacketFilter does not accept TURN ChannelData messages because they require knowledge of the value of the "Channel Number" field.

Constructor Detail

TurnDatagramPacketFilter

public TurnDatagramPacketFilter(TransportAddress turnServer)

Initializes a new TurnDatagramPacketFilter which will accept DatagramPackets which represent TURN messages and which are part of the communication with a specific TURN server.

Parameters:

turnServer - the TransportAddress of the TURN server DatagramPackets representing TURN messages from and to which will be accepted by the new instance

Method Detail

accept

public boolean accept(DatagramPacket p)

Determines whether a specific DatagramPacket represents a TURN message which is part of the communication with the TURN server associated with this instance.

Specified by:

accept in interface DatagramPacketFilter

Overrides:

accept in class StunDatagramPacketFilter

Parameters:

p - the DatagramPacket to be checked whether it represents a TURN message which is part of the communicator with the TURN server associated with this instance

Returns:

true if the specified DatagramPacket represents a TURN message which is part of the communication with the TURN server associated with this instance; otherwise, false

acceptMethod

protected boolean acceptMethod(char method)

Determines whether this DatagramPacketFilter accepts a DatagramPacket which represents a STUN message with a specific STUN method. TurnDatagramPacketFilter accepts TURN methods.

Overrides:

acceptMethod in class StunDatagramPacketFilter

Parameters:

method - the STUN method of a STUN message represented by a DatagramPacket to be checked whether it is accepted by this DatagramPacketFilter

Returns:

true if this DatagramPacketFilter accepts the DatagramPacket which represents a STUN message with the specified STUN method; otherwise, false
