All known Subclasses:   org.cougaar.core.persist.BufferedFilePersistence,  org.cougaar.core.persist.FilePersistence,
FilePersistenceBase
abstract public class FilePersistenceBase extends PersistencePluginAdapter implements PersistencePlugin,PersistenceNames(Code)
This PersistencePlugin abstract base class saves and restores blackboard objects in files. The actual opening of the input and output streams remains abstract.

There is one optional parameter naming the persistence root directory. If the parameter is omitted, the persistence root is specified by system properties.
