  org.hsqldb.DatabaseManager

public class DatabaseManager

extends Object

Multifunction class with all static methods.

Handles initial attempts to connect to HSQLDB databases within the JVM (or a classloader within the JVM). Opens the database if it is not open or connects to it if it is already open. This allows the same database to be used by different instances of Server and by direct connections.

Maintains a map of Server instances and notifies each server when its database has shut down.

Maintains a reference to the timer used for file locks and logging.

Parses a connection URL into parts.
