Constructor Detail

PacketWriter

public PacketWriter(int maxPacketSize)

Create a PacketWriter with an expected max packet size.

In theory we would prefer to create packets up to the MTU size which for Ethernet will likely be 1500. Note that the maxPacketSize is ignored for large single messages.

Method Detail

currentPacketId

public long currentPacketId()

Return the currentPacketId.

write

public List<Packet> write(boolean requiresAck,
                 List<? extends Message> messages)
                   throws IOException

Create Packets for a given list of messages.

Typically this creates a single Packet but there is a hard limit for UDP packet sizes.

Throws:

IOException

write

public List<Packet> write(RemoteTransactionEvent transEvent)
                   throws IOException

Create Packets for a given RemoteTransactionEvent.

Typically this creates a single Packet but there is a hard limit for UDP packet sizes.

Throws:

IOException
