Constructor Detail

OpenBasePlugIn

public OpenBasePlugIn(JDBCAdaptor adaptor)
Method Detail

connectionURL

public String connectionURL()
Description copied from class: JDBCPlugIn
Returns the JDBC URL to use for connecting to the database. The default implementation gets the URL from the adaptor.
Overrides:
connectionURL in class JDBCPlugIn
Following copied from class: com.webobjects.jdbcadaptor.JDBCPlugIn
Returns:
a JDBC URL
See Also:
JDBCAdaptor.connectionDictionaryURL()

createSynchronizationFactory

public EOSynchronizationFactory createSynchronizationFactory()
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:
createSynchronizationFactory in class JDBCPlugIn
Following copied from class: com.webobjects.jdbcadaptor.JDBCPlugIn
Returns:
a JDBCExpressionFactory
See Also:
JDBCPlugIn.synchronizationFactory()

databaseProductName

public String databaseProductName()
Description copied from class: JDBCPlugIn
Returns a string identifying the database. Subclasses should override.
Overrides:
databaseProductName in class JDBCPlugIn
Following copied from class: com.webobjects.jdbcadaptor.JDBCPlugIn
Returns:
a String identifying the database

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
Following copied from class: com.webobjects.jdbcadaptor.JDBCPlugIn
Returns:
JDBC driver class name

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
Following copied from class: com.webobjects.jdbcadaptor.JDBCPlugIn
Returns:
a Java Class (subclass of JDBCExpression)
See Also:
JDBCExpression, JDBCAdaptor.defaultExpressionClass()

isPseudoColumnName

public boolean isPseudoColumnName(String columnName)
Description copied from class: JDBCPlugIn
Determines if the column is a "pseudo" column. A pseudo column is one that was not part of the CREATE TABLE statement, but was created automatically by the database. These columns usually should not be considered for reverse engineering.
Overrides:
isPseudoColumnName in class JDBCPlugIn
Following copied from class: com.webobjects.jdbcadaptor.JDBCPlugIn
Returns:
true if the column should not be reverse engineered; false otherwise

jdbcInfo

public NSDictionary 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
Following copied from class: com.webobjects.jdbcadaptor.JDBCPlugIn
Returns:
an NSDictionary describing database-specific information about the JDBC data source
