Constructor Detail

PooledSessionTaskDispatcher

public PooledSessionTaskDispatcher(SessionInfo sessionInfo,
                                   int poolSize,
                                   String name,
                                   boolean useMutexLocking,
                                   long sleepInterval,
                                   boolean supervised,
                                   long deadInterval)

Creates a pooled db task dispatcher.

Parameters:

sessionInfo - the session info

poolSize - the fixed pool size

name - the pool name

useMutexLocking - true use a mutex for locking, else just a counter

sleepInterval - keep alive in milliseconds

supervised - true to use a DaemonSupervisor for each dispatcher

deadInterval - interval in milliseconds to detect a dead dispatcher, 0 to disable detection (ignored if supervised = false)

PooledSessionTaskDispatcher

public PooledSessionTaskDispatcher(SessionInfo sessionInfo,
                                   int poolSize,

                                   boolean useMutexLocking,
                                   long sleepInterval)

Creates a non-supervising pooled db task dispatcher.

Parameters:

sessionInfo - the session info

poolSize - the pool size

name - the pool name

useMutexLocking - true use a mutex for locking, else just a counter

sleepInterval - keep alive in milliseconds
