Creates a new platform instance.

Method Detail

getName

public String getName()

Returns the name of the database that this platform is for.

Returns:

The name

createDatabase

public void createDatabase(String jdbcDriverClassName,
                  String connectionUrl,
                  String username,
                  String password,
                  Map parameters)
                    throws DatabaseOperationException,
                           UnsupportedOperationException

Creates the database specified by the given parameters. Please note that this method does not use a data source set via Platform.setDataSource(DataSource) because it is not possible to retrieve the connection information from it without establishing a connection.
The given connection url is the url that you'd use to connect to the already-created database.
On some platforms, this method suppurts additional parameters. These are documented in the manual section for the individual platforms.

Specified by:

createDatabase in interface Platform

Overrides:

createDatabase in class PlatformImplBase

Parameters:

jdbcDriverClassName - The jdbc driver class name

connectionUrl - The url to connect to the database if it were already created

username - The username for creating the database

password - The password for creating the database

parameters - Additional parameters relevant to database creation (which are platform specific)

Throws:

DatabaseOperationException

UnsupportedOperationException

dropDatabase

public void dropDatabase(String jdbcDriverClassName,
                String connectionUrl,
                String username,
                String password)
                  throws DatabaseOperationException,
                         UnsupportedOperationException

Drops the database specified by the given parameters. Please note that this method does not use a data source set via Platform.setDataSource(DataSource) because it is not possible to retrieve the connection information from it without establishing a connection.

Specified by:

dropDatabase in interface Platform

Overrides:

dropDatabase in class PlatformImplBase

Parameters:

jdbcDriverClassName - The jdbc driver class name

connectionUrl - The url to connect to the database

username - The username for creating the database

password - The password for creating the database

Throws:

DatabaseOperationException

UnsupportedOperationException

setObject

protected void setObject(PreparedStatement statement,
             int sqlIndex,
             org.apache.commons.beanutils.DynaBean dynaBean,
             SqlDynaProperty property)
                  throws SQLException

Sets a parameter of the prepared statement based on the type of the column of the property.

Overrides:

setObject in class PlatformImplBase

Parameters:

statement - The statement

sqlIndex - The index of the parameter to set in the statement

dynaBean - The bean of which to take the value

property - The property of the bean, which also defines the corresponding column

Throws:

SQLException

getModelComparator

protected ModelComparator getModelComparator()

Returns the model comparator to be used for this platform. This method is intendeded to be redefined by platforms that need to customize the model reader.

Overrides:

getModelComparator in class PlatformImplBase

Returns:

The model comparator

getTableDefinitionChangesPredicate

protected TableDefinitionChangesPredicate getTableDefinitionChangesPredicate()

Returns the predicate that defines which changes are supported by the platform.

Overrides:

getTableDefinitionChangesPredicate in class PlatformImplBase

Returns:

The predicate

processChange

public void processChange(Database currentModel,
                 CreationParameters params,
                 RemoveColumnChange change)
                   throws IOException

Processes the removal of a column from a table.

Parameters:

currentModel - The current database schema

params - The parameters used in the creation of new tables. Note that for existing tables, the parameters won't be applied

change - The change object

Throws:

IOException
