Class TransformEngineChain.PacketTransformerChain

java.lang.Object

org.jitsi.impl.neomedia.transform.TransformEngineChain.PacketTransformerChain

All Implemented Interfaces:

PacketTransformer

Enclosing class:

TransformEngineChain

public class TransformEngineChain.PacketTransformerChain
extends Object
implements PacketTransformer

A PacketTransformerChain is a meta PacketTransformer that applies all transformers present in this engine chain. The class respects the order of the engine chain for outgoing packets and reverses it for incoming packets.

Constructor Summary

Constructor and Description
PacketTransformerChain(boolean rtp) Creates an instance of this packet transformer and prepares it to deal with RTP or RTCP according to the isRtp argument.

Constructor Detail

PacketTransformerChain

public PacketTransformerChain(boolean rtp)

Creates an instance of this packet transformer and prepares it to deal with RTP or RTCP according to the isRtp argument.

Parameters:

rtp - true if this transformer will be dealing with RTP (i.e. will transform packets via the RTP transformers in this chain rather than the RTCP ones) and false otherwise.

Method Detail

close

public void close()

Close the transformer and underlying transform engines. Propagate the close to all transformers in chain.

Specified by:

close in interface PacketTransformer

reverseTransform

public RawPacket[] reverseTransform(RawPacket[] pkts)

Reverse-transforms each packet in an array of packets. Null values must be ignored. Reverse-transforms the given packets using each of the TransformEngine-s in the engine chain in reverse order.

Specified by:

reverseTransform in interface PacketTransformer

Parameters:

pkts - the transformed packets to be restored.

Returns:

the restored packets.

transform

public RawPacket[] transform(RawPacket[] pkts)

Transforms each packet in an array of packets. Null values must be ignored. Transforms the specified pkts using each of the TransformEngines in the chain in order.

Specified by:

transform in interface PacketTransformer

Parameters:

pkts - the packets to be transformed

Returns:

the transformed packets

transform

public RawPacket[] transform(RawPacket[] pkts,
                             TransformEngine after)

Transforms the specified pkts using the TransformEngines in the chain in order starting after a specific TransformEngine.

Parameters:

pkts - the array of RawPackets to transform

after - the TransformEngine in the chain after which the transformation is to begin. If after is not in the chain, the transformation executes through the whole chain.

Returns:

the array of RawPackets that is the result of the transformation of pkts using the TransformEngines in the chain
