Interface ILink3Connection

All Superinterfaces:

FixPConnection

public interface ILink3Connection
extends FixPConnection

Represents a Session Connection of the iLink3 protocol. This is a FIXP session protocol with SBE encoded binary messages. Unlike FIX it possible to have multiple connections open with the same session id.

Method Detail

terminate

void terminate(java.lang.String shutdown,
               int errorCodes)

Initiate a termination. This sends a Terminate message to initiate the termination. Artio's session will await an acknowledging Terminate message from the exchange. If keepAliveInterval elapses without a reply then a TCP disconnect will happen.

Parameters:

shutdown - the shutdown text to send in the Terminate message

errorCodes - the error codes to send in the Terminate message

uuid

long uuid()

Gets the UUID of the current connection for this session.

Returns:

the UUID of the current connection for this session.

lastUuid

long lastUuid()

Gets the UUID of the last success connection for this session.

Returns:

the UUID of the last success connection for this session.

tryRetransmitRequest

long tryRetransmitRequest(long uuid,
                          long fromSeqNo,
                          int msgCount)

Send a custom retransmit request.

Parameters:

uuid - the UUID of the connection to request a retransmit request. This doesn't necessarily have to be the current UUID, but it does have to be one for the same session on the same market segment.

fromSeqNo - the sequence number to start from.

msgCount - the number of messages to request a retransmit of.

Returns:

the position in the stream that corresponds to the end of this message or a negative number indicating an error status.

retransmitFillSeqNo

long retransmitFillSeqNo()

Gets the next received sequence number that will fill the current retransmit request. If there is no retransmit operation in process NOT_AWAITING_RETRANSMIT will be returned.

Returns:

the next received sequence number that will fill the current retransmit request.

nextRetransmitSeqNo

long nextRetransmitSeqNo()

Gets the next sequence number that Artio expects to received in the current retransmit request. If there is no retransmit operation in process NOT_AWAITING_RETRANSMIT will be returned.

Returns:

the next sequence number that Artio expects to received in the current retransmit request.
