      Modifier and Type Method Description
      boolean accept(DatagramPacket p) Determines whether a specific DatagramPacket represents a STUN message and whether it is part of the communication with the STUN server if one was associated with this instance.
      boolean equals(Object obj) Indicates whether some other object is "equal to" this one.
      int hashCode() Returns a hash code value for this object for the benefit of hashtables such as those provided by Hashtable.
      static boolean isStunPacket(DatagramPacket p) Determines whether a specific DatagramPacket represents a STUN (or TURN) packet.

      • StunDatagramPacketFilter

        StunDatagramPacketFilter()
        Initializes a new StunDatagramPacketFilter which will accept DatagramPackets which represent STUN messages received from any destination.

      • StunDatagramPacketFilter

        StunDatagramPacketFilter(TransportAddress stunServer)
        Initializes a new StunDatagramPacketFilter which will accept DatagramPackets which represent STUN messages and which are part of the communication with a specific STUN server (or any server if stunServer is null).
        Parameters:
        stunServer - the TransportAddress of the STUN server DatagramPackets representing STUN messages from and to which will be accepted by the new instance or null if we would like to accept stun messages from any destination.

    • Method Detail

      • accept

         boolean accept(DatagramPacket p)

        Determines whether a specific DatagramPacket represents a STUN message and whether it is part of the communication with the STUN server if one was associated with this instance.

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

      • equals

         boolean equals(Object obj)

        Indicates whether some other object is "equal to" this one.

        Parameters:
        obj - the reference object with which to compare.

      • hashCode

         int hashCode()

        Returns a hash code value for this object for the benefit of hashtables such as those provided by Hashtable.

      • isStunPacket

         static boolean isStunPacket(DatagramPacket p)

        Determines whether a specific DatagramPacket represents a STUN (or TURN) packet.

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