HSMSConnectionManager

public HSMSConnectionManager(PortManager hsm)

The constructor for the portManager.

HSMSConnectionManager

public HSMSConnectionManager(java.lang.String hostname,
                             int port)
                      throws java.io.IOException

Throws:

java.io.IOException

Method Detail

addSessionManager

public void addSessionManager(SessionManager hsm)

Add a session manager. This will become the session manager for the session id it is managing.

Overrides:

public int getT5()

This is the T5 timeout. Control Trancsaction Timeout.

getT6

public int getT6()

This is the T6 timeout. Control Trancsaction Timeout.

getT7

public int getT7()

This is the T7 timeout. Time which a TCP/IP connection can remain in NOT SELECTED stat (i.e., no HSMS activity) before it is considered a communictaion failure.

getT8

public double getT8()

This is the T8 timeout. This is defined as the Network Intercharacter Timeout

isSelected

public boolean isSelected()

isSingleSession

public boolean isSingleSession()

Returns true if the current session is a single session.
