Method Detail

startOrCheck

public boolean startOrCheck(DbConfigManager configMgr)

Returns true if this thread will perform auto-repair, or false if the background DataVerifier should be configured as usual.

If true is returned, the background DataVerifier will be configured as usual by this thread after the auto-repair is complete.

This method's implementation is fairly simple due to the following:

• The caller, EnvironmentImpl.doSetMutableConfig(com.sleepycat.je.EnvironmentMutableConfig), is synchronized.
• The first call, when 'initialized' is false, is made before the Environment ctor returns.
• The repair param is immutable.

Throws:

IllegalArgumentException - if the repair param is invalid.

isCompleted

public boolean isCompleted()

isRunning

public boolean isRunning()

getLogger

public Logger getLogger()

Specified by:

getLogger in class StoppableThread

Returns:

a logger to use when logging uncaught exceptions.

requestShutdown

public void requestShutdown()

initiateSoftShutdown

protected int initiateSoftShutdown()

Description copied from class: StoppableThread

Threads that use shutdownThread() must define this method. It's invoked by shutdownThread as an attempt at a soft shutdown. This method makes provisions for this thread to exit on its own. The technique used to make the thread exit can vary based upon the nature of the service being provided by the thread. For example, the thread may be known to poll some shutdown flag on a periodic basis, or it may detect that a channel that it waits on has been closed by this method.

Overrides:

initiateSoftShutdown in class StoppableThread

Returns:

the amount of time in ms that the shutdownThread method will wait for the thread to exit. A -ve value means that the method will not wait. A zero value means it will wait indefinitely.

run

public void run()

Specified by:

run in interface Runnable

Overrides:

run in class Thread
