Class ConnectionManagerUtil


  • public class ConnectionManagerUtil
    extends Object
    Collects utility methods related to connection managers. Connection manager factories should be registered as extensions to the net.sf.basedb.core.uri.connection-manager extension point. The methods in this class can then be used to get information about installed connection manager factories and to use them for retreiving external file data and information.

      • getFactories

        public static List<ConnectionManagerFactory> getFactories()
        Get a list with all connection manager factories. No context information will be available to the action factories that creates the connection manager factories.
        Returns:
        A list with the factories
      • getFactory

        public static ConnectionManagerFactory getFactory​(String id)
        Get the connection manager factory with the given extension id. No context information will be available to the factory when it is created.
        Parameters:
        id - The ID of the factory
        Returns:
        A factory instance or null if not found
      • findFactory

        public static ConnectionManagerFactory findFactory​(URI uri)
        Find a factory for the given URI. This method will iterate the registered factories in their priority/index order and call ConnectionManagerFactory.supports(URI) for all factories that supports auto-detection. The first one that gives a successful response is returned. If no factory supports the given URI, null is returned.

        Note to extension developers: The given uri is available to the action factory as "uri" attribute of the context.

        Parameters:
        uri - The URI (null is not allowed)
        Returns:
        An UriHandlerFactory or null if no factory was found
      • createConnectionManager

        public static ConnectionManager createConnectionManager​(URI uri,
                                                                ConnectionParameters parameters)
        Utility method for creating a connection manager. If a specific factory is specified in the connection parameters, that factory is used, otherwise findFactory(URI) is used for auto-detection. If no factory is found an exception is thrown, otherwise a connection manger is created by the factory method: ConnectionManagerFactory.createConnectionManager(URI, ConnectionParameters)
        Parameters:
        uri - The URI (required)
        parameters - Connection parameters, such as user login/password, etc. (optional)
        Returns:
        A connection manager
      • createConnectionManager

        public static ConnectionManager createConnectionManager​(File file,
                                                                ConnectionParameters parameters)
        Utility method for creating a connection manager for a file item. If a specific factory is specified in the connection parameters, that factory is used, otherwise auto-detection is used. The auto-detection is similar to the findFactory(URI) method but this time the context information for the action factory contains the file object and connection parameters.
        Parameters:
        file - The (external) file (required)
        parameters - Connection parameters, such as user login/password, etc. (optional)
        Returns:
        A connection manager
