Method Detail

open

public void open()

Description copied from interface: SessionStorage

Opens session storage.

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

getMessage

Parameters:

direction - message direction

sequenceNumber - message sequence number

Returns:

message or null if not available

getMessages

Description copied from interface: SessionStorage

Returns messages with the specified direction and sequence number interval. Ends are included.

Parameters:

direction - messages direction
