Constructor Detail

CachingTransformer

public CachingTransformer(MediaStreamImpl stream)

Initializes a new CachingTransformer instance.

Parameters:

stream - the owning stream.

Method Detail

close

public void close()

Closes this PacketTransformer i.e. releases the resources allocated by it and prepares it for garbage collection. The (default) implementation of SinglePacketTransformer does nothing.

Specified by:

close in interface PacketTransformer

Overrides:

close in class SinglePacketTransformer

transform

public RawPacket transform(RawPacket pkt)

Transforms a specific packet. Transforms an outgoing packet.

Overrides:

transform in class SinglePacketTransformerAdapter

Parameters:

pkt - the packet to be transformed.

Returns:

the transformed packet.

reverseTransform

public RawPacket reverseTransform(RawPacket pkt)

Description copied from class: SinglePacketTransformer

Reverse-transforms a specific packet.

Overrides:

reverseTransform in class SinglePacketTransformerAdapter

Parameters:

pkt - the transformed packet to be restored.

Returns:

the restored packet.

getRTPTransformer

public PacketTransformer getRTPTransformer()

Gets the PacketTransformer for RTP packets.

Specified by:

getRTPTransformer in interface TransformEngine

Returns:

the PacketTransformer for RTP packets

getRTCPTransformer

public PacketTransformer getRTCPTransformer()

Gets the PacketTransformer for RTCP packets.

Specified by:

getRTCPTransformer in interface TransformEngine

Returns:

the PacketTransformer for RTCP packets

getTimeUntilNextRun

public long getTimeUntilNextRun()

Specified by:

getTimeUntilNextRun in interface org.jitsi.utils.concurrent.RecurringRunnable

run

public void run()

Specified by:

run in interface Runnable

setEnabled

public void setEnabled(boolean enabled)

Enables/disables the caching of packets.

Parameters:

enabled - true if the caching of packets is to be enabled or false if the caching of packets is to be disabled

getOutgoingRawPacketCache

public RawPacketCache getOutgoingRawPacketCache()

Gets the outgoing RawPacketCache.

Returns:

the outgoing RawPacketCache.

getIncomingRawPacketCache

public RawPacketCache getIncomingRawPacketCache()

Gets the incoming RawPacketCache.

Returns:

the incoming RawPacketCache.
