Package net.minecraft.network.message

Class LastSeenMessagesCollector

java.lang.Object

net.minecraft.network.message.LastSeenMessagesCollector

public class LastSeenMessagesCollector
extends Object

Collects the message that are last seen by a client.

The message, along with the "last received" message, forms an "acknowledgment" of received messages. They are sent to the server when the client has enough messages received or when they send a message.

See Also:

• AcknowledgmentValidator
• LastSeenMessageList

Implementation Note:

The maximum amount of message entries are specified in the constructor. The vanilla clients collect 5 entries. Calling add(MessageSignatureData, boolean) adds the message to the beginning of the entries list, and evicts the oldest message. If there are entries with the same sender profile ID, the older entry will be replaced with null instead of filling the hole.
