Method Detail

getName

public String getName()

Specified by:

getName in interface DatabaseType

Specified by:

getName in class BaseDatabaseType

Returns:

The human-readable name for this database.

getNullType

public int getNullType()

Specified by:

getNullType in interface DatabaseType

Specified by:

getNullType in class BaseDatabaseType

Returns:

The JDBC type used to represent null in prepared statements.

getPriority

public int getPriority()

Description copied from class: BaseDatabaseType

When identifying database types, the priority with which this type will be used. High numbers indicate that this type will be used in preference to others.

Specified by:

getPriority in interface DatabaseType

Overrides:

getPriority in class BaseDatabaseType

handlesJDBCUrl

public boolean handlesJDBCUrl(String url)

Description copied from class: BaseDatabaseType

Whether this database type should handle the given JDBC url.

Specified by:

handlesJDBCUrl in interface DatabaseType

Specified by:

handlesJDBCUrl in class BaseDatabaseType

Parameters:

url - The JDBC url.

Returns:

true if this handles the JDBC url, false if not.

getDriverClass

public String getDriverClass(String url,
                             ClassLoader classLoader)

Description copied from interface: DatabaseType

Get the driver class used to handle this JDBC url. This will only be called if matchesJDBCUrl previously returned true.

Specified by:

getDriverClass in interface DatabaseType

Specified by:

getDriverClass in class BaseDatabaseType

Parameters:

url - The JDBC url.

classLoader - The classLoader to check for driver classes.

Returns:

The full driver class name to be instantiated to handle this url.

handlesDatabaseProductNameAndVersion

public boolean handlesDatabaseProductNameAndVersion(String databaseProductName,
                                                    String databaseProductVersion,
                                                    Connection connection)

Description copied from class: BaseDatabaseType

This allows more fine-grained control over which DatabaseType handles which connection. MigrateDB will use the first DatabaseType that returns true for this method.

Specified by:

handlesDatabaseProductNameAndVersion in interface DatabaseType

Specified by:

handlesDatabaseProductNameAndVersion in class BaseDatabaseType

Parameters:

databaseProductName - The product name returned by the database.

databaseProductVersion - The product version returned by the database.

connection - The connection used to connect to the database.

Returns:

true if this handles the product name and version, false if not.

createDatabase

public Database<?> createDatabase(Configuration configuration,
                                  JdbcConnectionFactory jdbcConnectionFactory)

Description copied from interface: DatabaseType

Initializes the Database used by this Database Type.

Specified by:

createDatabase in interface DatabaseType

Specified by:

createDatabase in class BaseDatabaseType

Parameters:

configuration - The MigrateDB configuration.

jdbcConnectionFactory - The current connection factory.

Returns:

The Database.

createParser

public BaseParser createParser(Configuration configuration,
                               ResourceProvider resourceProvider,
