Method Detail

getDriverClassNameForDatabase

public String getDriverClassNameForDatabase(DatabaseType databaseType)

Returns the driver class for the database platform.

Specified by:

getDriverClassNameForDatabase in interface DatabasePlatformSupport

Parameters:

databaseType - - The database type used to lookup the driver class name. Must not be null

Returns:

- The driver class name, is never null

Throws:

IllegalArgumentException - if there is no driver class name available for the DatabaseType

getDatabaseUrlForDatabase

public String getDatabaseUrlForDatabase(DatabaseType databaseType,
                                        String hostname,
                                        int port,
                                        String databaseName)

Constructs the URL for the database by using a URI to construct the URL.

Specified by:

getDatabaseUrlForDatabase in interface DatabasePlatformSupport

Parameters:

databaseType - - The databaseType for which the URL should be constructed.

hostname - - The hostname without any port information used to connect to.

port - - The port used to connect to the database

databaseName - - The database name used to connect to. The usage is implementation specific (e.g. for Oracle this is the SID)

Returns:

- the database specific URL

Throws:

IllegalArgumentException - if there is no scheme available for the database type or if the information is not valid to construct a URL.

getDriverClassNameMappings

protected abstract Map<DatabaseType,String> getDriverClassNameMappings()

Template method that must be implemented in order to retrieve all driver class names for every supported database platform.

Returns:

Map containing the driver class name for every database platform

getSchemeNames

protected abstract Map<DatabaseType,String> getSchemeNames()

Template method that mus be implemented to get all scheme names for every supported database platform. Scheme names are unfortunately only standardized in the root scheme (jdbc:) but not in the sub-scheme which is database platform specific.

Returns:

Map containing the schema (and sub-scheme) names for every support database platform

getAuthenticationInfo

protected abstract Map<DatabaseType,String> getAuthenticationInfo()
