Class FileImpl

java.lang.Object
  netbattle.database.registry.AccountRegistry
      netbattle.database.registry.FileImpl

public class FileImpl
extends AccountRegistry

This is an implementation of the AccountRegistry that uses only flat files. The impl. works by internally storing the registry data as a HashMap. When an instance is created, the map is unseralised from a file. When the close method is called, the map is seralised to the same file. To reduce susceptibility to data loss, the data is also serialised periodically, as specified when the class is instantiated.
