 com.db4o.Db4o
All known Subclasses: com.db4o.ext.ExtDb4o,
| Method Summary | |
| public static Configuration | cloneConfiguration()
Creates a clone of the global db4o
Configuration Configuration . | | public static Configuration | configure()
returns the global db4o
Configuration Configuration context
for the running JVM session. | | public static void | main(String args)
prints the version name of this db4o version to System.out. | | public static Configuration | newConfiguration()
Creates a fresh
Configuration Configuration instance. | | public static ObjectContainer | openClient(String hostName, int port, String user, String password)
Operates just like
Db4o.openClient(ConfigurationStringintStringString) , but uses
the global db4o
Configuration Configuration context. | | public static ObjectContainer | openClient(Configuration config, String hostName, int port, String user, String password)
opens an
ObjectContainer ObjectContainer client and connects it to the specified named server and port. | | public static ObjectContainer | openClient(Configuration config, String hostName, int port, String user, String password, NativeSocketFactory socketFactory)
opens an
ObjectContainer ObjectContainer client and connects it to the specified named server and port. | | final public static ObjectContainer | openFile(String databaseFileName)
Operates just like
Db4o.openFile(ConfigurationString) , but uses
the global db4o
Configuration Configuration context.
opens an
ObjectContainer ObjectContainer on the specified database file for local use.
A database file can only be opened once, subsequent attempts to open
another
ObjectContainer ObjectContainer against the same file will result in
a
DatabaseFileLockedException DatabaseFileLockedException .
Database files can only be accessed for readwrite access from one process
(one Java VM) at one time. | | final public static ObjectContainer | openFile(Configuration config, String databaseFileName)
opens an
ObjectContainer ObjectContainer on the specified database file for local use.
A database file can only be opened once, subsequent attempts to open
another
ObjectContainer ObjectContainer against the same file will result in
a
DatabaseFileLockedException DatabaseFileLockedException .
Database files can only be accessed for readwrite access from one process
(one Java VM) at one time. | | final protected static ObjectContainer | openMemoryFile1(Configuration config, MemoryFile memoryFile)
| | final public static ObjectServer | openServer(String databaseFileName, int port)
Operates just like
Db4o.openServer(ConfigurationStringint) , but uses
the global db4o
Configuration Configuration context.
opens an
ObjectServer ObjectServer on the specified database file and port.
If the server does not need to listen on a port because it will only be used
in embedded mode with
ObjectServer.openClient , specify '0' as the
port number.
Parameters:
databaseFileName - an absolute or relative path to the database file
Parameters:
port - the port to be used, or 0, if the server should not open a port,because it will only be used with ObjectServer.openClient.Specify a value < 0 if an arbitrary free port should be chosen - see ExtObjectServer.port. | | final public static ObjectServer | openServer(Configuration config, String databaseFileName, int port)
opens an
ObjectServer ObjectServer on the specified database file and port.
If the server does not need to listen on a port because it will only be used
in embedded mode with
ObjectServer.openClient , specify '0' as the
port number.
Parameters:
config - a custom Configuration Configuration instance to be obtained via Db4o.newConfiguration
Parameters:
databaseFileName - an absolute or relative path to the database file
Parameters:
port - the port to be used, or 0, if the server should not open a port,because it will only be used with ObjectServer.openClient.Specify a value < 0 if an arbitrary free port should be chosen - see ExtObjectServer.port. | | final public static ObjectServer | openServer(Configuration config, String databaseFileName, int port, NativeSocketFactory socketFactory)
opens an
ObjectServer ObjectServer on the specified database file and port.
If the server does not need to listen on a port because it will only be used
in embedded mode with
ObjectServer.openClient , specify '0' as the
port number.
Parameters:
config - a custom Configuration Configuration instance to be obtained via Db4o.newConfiguration
Parameters:
databaseFileName - an absolute or relative path to the database file
Parameters:
port - the port to be used, or 0, if the server should not open a port,because it will only be used with ObjectServer.openClient.Specify a value < 0 if an arbitrary free port should be chosen - see ExtObjectServer.port.
Parameters:
socketFactory - the NativeSocketFactory to be used for socket creation an ObjectServer ObjectServer listeningon the specified port.
