Constructor Details

HostSendSequencedData

public HostSendSequencedData(byte regionID,
 byte sequenceNum,
 EIEIODataMessage eieioDataMessage)

Create a message.

Parameters:

regionID - The region ID

sequenceNum - The sequence number

eieioDataMessage - The payload data.

Method Details

minPacketLength

public int minPacketLength()

Specified by:

minPacketLength in interface EIEIOMessage<EIEIOCommandMessage.Header>

Overrides:

minPacketLength in class EIEIOCommandMessage

Returns:

the minimum length of a message instance in bytes.

addToBuffer

public void addToBuffer(ByteBuffer buffer)

Description copied from interface: SerializableMessage

Writes this message into the given buffer as a contiguous range of bytes. This is so that a message can be sent. Implementors may assume that the buffer has been configured to be little-endian and that its position is at the point where they should begin writing. Once it has finished, the position should be immediately after the last byte written by this method.

Calling this method should not update the internal state of the message. It should be possible to add the message to multiple buffers without special precautions by the caller.

Specified by:

addToBuffer in interface SerializableMessage

Overrides:

addToBuffer in class EIEIOCommandMessage

Parameters:

buffer - The buffer to write into.
