Method Detail

clear

public void clear()

Description copied from interface: SessionStorage

Clears session storage state. Inbound and outbound sequence numbers are reset to 0.

close

public void close(boolean terminated)

Description copied from interface: SessionStorage

Closes session storage.
The terminated set to true means that after closing this session storage can not be restored. Its state is vanished. The session with the same parameters will be started from scratch.
The terminated set to false means that after closing this session can be restored at some point in the future. The session state need to be kept - sequence numbers, etc.

Parameters:

terminated - controls whether this session storage state should be kept or cleaned

getOutboundMessages

public List<FixMessage> getOutboundMessages(long beginSequenceNumber,
                                            long endSequenceNumber)

Description copied from interface: SessionStorage

Returns outbound messages with the specified sequence number interval. Ends are included.
Warning. This is critical to avoid using the method directly.

Parameters:

beginSequenceNumber - sequence number to begin with, 0 means the minimum available

endSequenceNumber - sequence number to end with, 0 means the maximum available

Returns:

outbound messages

storeInboundMessage

public void storeInboundMessage(ByteBuffer rawMessage,
                                long msgSeqNum,
                                boolean isOriginal)

Description copied from interface: SessionStorage

Stores inbound message.

Parameters:

rawMessage - message to store

msgSeqNum - message sequence number

isOriginal - whether message is original or not

storeOutboundMessage

public void storeOutboundMessage(ByteBuffer rawMessage,
                                 long msgSeqNum,
                                 boolean isOriginal,
                                 boolean warmUp)

Description copied from interface: SessionStorage

Stores outbound message.

Parameters:

rawMessage - message to store

msgSeqNum - message sequence number

isOriginal - whether message is original or not

warmUp - indicates whether it is a warmUp message

getId

public String getId()

Description copied from interface: SessionStorage

Returns session storage unique id.

Returns:

session storage unique id

getInSeqNum

public long getInSeqNum()

Description copied from interface: SessionStorage

Returns last inbound message sequence number or 0 if no inbound message is stored.

Returns:

inbound sequence number

setInSeqNum

public void setInSeqNum(long msgSeqNum)

Description copied from interface: SessionStorage

Sets last inbound message sequence number

Parameters:

getOutSeqNum

public long getOutSeqNum()

Description copied from interface: SessionStorage

Returns last outbound sequence number or 0 if no outbound message is stored.

Returns:

setOutSeqNum

public void setOutSeqNum(long msgSeqNum)

Description copied from interface: SessionStorage

isTerminated

public boolean isTerminated()

Description copied from interface: SessionStorage

Returns the flag whether this storage state should be kept or cleaned.

Returns:

flag whether this storage state should be kept or cleaned

setTerminated

public void setTerminated(boolean terminated)

Description copied from interface: SessionStorage

Sets the flag whether this storage state should be kept or cleaned

Parameters:

setMaxStorageSize

public void setMaxStorageSize(int maxStorageSize)

Description copied from interface: SessionStorage

Sets the maximum size of the message storage.
The details depend on the selected storage implementation.

Specified by:
