requestShutdown

public void requestShutdown()

Specified by:

requestShutdown in interface MigrationService.MigrationContext

isShutdownRequested

public boolean isShutdownRequested()

Description copied from interface: MigrationService.MigrationContext

Checks if shutdown has been requested.

This should be checked periodically by the migrator, and when true the migrator should return as soon as possible, even if its work is not complete.

This is a "nice" version of thread interruption, which will follow a short while later, and should also be checked by the migrator.

Specified by:

isShutdownRequested in interface MigrationService.MigrationContext

Returns:

true if migration should be stopped as soon as possible
