Special collection that is optimized for tracking unacknowledged packets

Public Methods

Method	Description
Acknowledge ( uint sequenceNumber, int currentTime, bool fromResend ) : void	Marks a packet as acknowledged This method is used when an acknowledgement is received from the network for a previously sent packet. Effects of removal this way are to update unacked byte count, adjust RTT and increase throttle to the corresponding client. This does not immediately acknowledge the packet, it only queues the ack so it can be handled in a thread-safe way later
Add ( OutgoingPacket packet ) : void	Add an unacked packet to the collection This does not immediately add the ACK to the collection, it only queues it so it can be added in a thread-safe way later
GetExpiredPackets ( int timeoutMS ) : List	Returns a list of all of the packets with a TickCount older than the specified timeout This function is not thread safe, and cannot be called multiple times concurrently
Remove ( uint sequenceNumber ) : void	Marks a packet as no longer needing acknowledgement without a received acknowledgement. This method is called when a packet expires and we no longer need an acknowledgement. When some reliable packet types expire, they are handled in a way other than simply resending them. The only effect of removal this way is to update unacked byte count. The does not immediately remove the packet, it only queues the removal so it can be handled in a thread safe way later

Method Details

Acknowledge() public method

Marks a packet as acknowledged This method is used when an acknowledgement is received from the network for a previously sent packet. Effects of removal this way are to update unacked byte count, adjust RTT and increase throttle to the corresponding client.

This does not immediately acknowledge the packet, it only queues the ack so it can be handled in a thread-safe way later

public Acknowledge ( uint sequenceNumber, int currentTime, bool fromResend ) : void
sequenceNumber	uint	/// Sequence number of the packet to /// acknowledge ///
currentTime	int	Current value of Environment.TickCount
fromResend	bool
return	void

Add() public method

Add an unacked packet to the collection

This does not immediately add the ACK to the collection, it only queues it so it can be added in a thread-safe way later

public Add ( OutgoingPacket packet ) : void
packet	OutgoingPacket	Packet that is awaiting acknowledgement
return	void

GetExpiredPackets() public method

Returns a list of all of the packets with a TickCount older than the specified timeout

This function is not thread safe, and cannot be called multiple times concurrently

public GetExpiredPackets ( int timeoutMS ) : List
timeoutMS	int	/// Number of ticks (milliseconds) before a /// packet is considered expired ///
return	List

Remove() public method

Marks a packet as no longer needing acknowledgement without a received acknowledgement. This method is called when a packet expires and we no longer need an acknowledgement. When some reliable packet types expire, they are handled in a way other than simply resending them. The only effect of removal this way is to update unacked byte count.

The does not immediately remove the packet, it only queues the removal so it can be handled in a thread safe way later

public Remove ( uint sequenceNumber ) : void
sequenceNumber	uint	/// Sequence number of the packet to /// acknowledge ///
return	void
