Constructor Detail

MySQLPlugIn

public MySQLPlugIn(JDBCAdaptor adaptor)

Method Detail

name

public String name()

Description copied from class: JDBCPlugIn

Returns the plugin's name. Subclasses of JDBCPlugIn need to override this method.

Overrides:

name in class JDBCPlugIn

Returns:

The name of the receiver.

defaultDriverName

public String defaultDriverName()

Description copied from class: JDBCPlugIn

Returns a fully qualified name of the JDBC driver class that this plugin prefers to use. The adaptor will attempt to load this class when making a connection. Subclasses should override.

Overrides:

defaultDriverName in class JDBCPlugIn

Returns:

JDBC driver class name

databaseProductName

public String databaseProductName()

Description copied from class: JDBCPlugIn

Returns a string identifying the database. Subclasses should override.

Overrides:

databaseProductName in class JDBCPlugIn

Returns:

a String identifying the database

defaultExpressionClass

public Class defaultExpressionClass()

Description copied from class: JDBCPlugIn

Returns the Java Class to use as the expression class. The default is JDBCExpression. Subclasses will typically override to use their own subclass of JDBCExpression.

Overrides:

defaultExpressionClass in class JDBCPlugIn

Returns:

a Java Class (subclass of JDBCExpression)

See Also:

JDBCExpression, JDBCAdaptor#defaultExpressionClass

createSchemaSynchronizationFactory

public EOSchemaSynchronizationFactory createSchemaSynchronizationFactory()

Description copied from class: JDBCPlugIn

Creates a new EOSynchronizationFactory using the plugin's response to adaptor(). The default EOSynchronizationFactory supports only basic SQL table generation. Subclasses need to override this method to support schema synchronization.

Overrides:

createSchemaSynchronizationFactory in class JDBCPlugIn

Returns:

a JDBCExpressionFactory

See Also:

JDBCPlugIn.synchronizationFactory()

jdbcInfo

public NSDictionary<String,Object> jdbcInfo()

Description copied from class: JDBCPlugIn

Returns database-specific information about the JDBC data source. Subclasses may want to return a modified copy of the dictionary returned by calling super.

Overrides:

jdbcInfo in class JDBCPlugIn

Returns:

an NSDictionary describing database-specific information about the JDBC data source

fetchBLOB

public Object fetchBLOB(ResultSet rs,
                        int column,
                        EOAttribute attribute,
                        boolean materialize)
                 throws SQLException

Description copied from class: JDBCPlugIn

Fetch a BLOB. This supports a database-specific way of fetching a BLOB so plugin subclasses need to override the default, which simply returns null.

Overrides:

fetchBLOB in class JDBCPlugIn

Parameters:

rs - the current ResultSet

column - the column index corresponding to the BLOB

attribute - the attribute mapped to the BLOB

materialize - a boolean that determines if the BLOB should be fully "materialized" (if true) or left as a reference (if false)

Throws:

SQLException
