## Class JDBCCommonDataSource

- java.lang.Object
- - org.hsqldb.jdbc.JDBCCommonDataSource

- All Implemented Interfaces:
    Serializable, CommonDataSource
  Direct Known Subclasses:
    JDBCDataSource, JDBCPooledDataSource, JDBCXADataSource

      public abstract class JDBCCommonDataSource
      extends Object
      implements CommonDataSource, Serializable

  Common base for DataSource implementations. This class implements the methods used for setting the properties for new connections. The setUrl() or setDatabase() methods are used to set the URL. It is possible to set all the rest of required properties in a Properties file and use the setProperties() method. Alternatively, the setXXX() methods for user and password can be used. It is best to use only one method for setting the properties. If setXXX() methods are used, the values override the values set in a call made to setProperties() before or after calling setXXX().

    - #### getLogWriter

          public PrintWriter getLogWriter()
                                   throws SQLException

      Retrieves the log writer for this `DataSource` object.

      The log writer is a character output stream to which all logging and tracing messages for this data source will be printed. This includes messages printed by the methods of this object, messages printed by methods of other objects manufactured by this object, and so on. Messages printed to a data source specific log writer are not printed to the log writer associated with the `java.sql.DriverManager` class. When a `DataSource` object is created, the log writer is initially null; in other words, the default is for logging to be disabled.

      Specified by:
        `getLogWriter` in interface `CommonDataSource`
      Returns:
        the log writer for this data source or null if logging is disabled
      Throws:
        `SQLException` - if a database access error occurs

    - #### setLogWriter

          public void setLogWriter(PrintWriter out)
                            throws SQLException

      Sets the log writer for this `DataSource` object to the given `java.io.PrintWriter` object.

      The log writer is a character output stream to which all logging and tracing messages for this data source will be printed. This includes messages printed by the methods of this object, messages printed by methods of other objects manufactured by this object, and so on. Messages printed to a data source- specific log writer are not printed to the log writer associated with the `java.sql.DriverManager` class. When a `DataSource` object is created the log writer is initially null; in other words, the default is for logging to be disabled.

      Specified by:
        `setLogWriter` in interface `CommonDataSource`
      Parameters:
        `out` - the new log writer; to disable logging, set to null
      Throws:
        `SQLException` - if a database access error occurs

    - #### setLoginTimeout

          public void setLoginTimeout(int seconds)
                               throws SQLException

      Sets the maximum time in seconds that this data source will wait while attempting to connect to a database. A value of zero specifies that the timeout is the default system timeout if there is one; otherwise, it specifies that there is no timeout. When a `DataSource` object is created, the login timeout is initially zero.

      Specified by:
        `setLoginTimeout` in interface `CommonDataSource`
      Parameters:
        `seconds` - the data source login time limit
      Throws:
        `SQLException` - if a database access error occurs.

    - #### getLoginTimeout

          public int getLoginTimeout()
                              throws SQLException

      Gets the maximum time in seconds that this data source can wait while attempting to connect to a database. A value of zero means that the timeout is the default system timeout if there is one; otherwise, it means that there is no timeout. When a `DataSource` object is created, the login timeout is initially zero.
      Specified by:
        `getLoginTimeout` in interface `CommonDataSource`

      Return the parent Logger of all the Loggers used by this data source. This should be the Logger farthest from the root Logger that is still an ancestor of all of the Loggers used by this data source.
