Constructor Detail

TransformInputStream

protected TransformInputStream(T socket)

Initializes a new TransformInputStream which is to transform the packets received from a specific (network) socket.

Parameters:

socket - the (network) socket from which packets are to be received and transformed by the new instance

Method Detail

createRawPacket

protected RawPacket[] createRawPacket(DatagramPacket datagramPacket)

Creates a new RawPacket array from a specific DatagramPacket in order to have this instance receive its packet data through its RTPConnectorInputStream.read(byte[], int, int) method. Reverse-transforms the received packet.

Overrides:

createRawPacket in class RTPConnectorInputStream<T extends Closeable>

Parameters:

datagramPacket - the DatagramPacket containing the packet data

Returns:

a new RawPacket array containing the packet data of the specified DatagramPacket or possibly its modification; null to ignore the packet data of the specified DatagramPacket and not make it available to this instance through its RTPConnectorInputStream.read(byte[], int, int) method

See Also:

RTPConnectorInputStream.createRawPacket(DatagramPacket)

getTransformer

public PacketTransformer getTransformer()

Gets the PacketTransformer which is used to reverse-transform packets.

Returns:

the PacketTransformer which is used to reverse-transform packets

setTransformer

public void setTransformer(PacketTransformer transformer)

Sets the PacketTransformer which is to be used to reverse-transform packets. Set to null to disable transformation.

Parameters:

transformer - the PacketTransformer which is to be used to reverse-transform packets.
