Method Detail

appendExpressionToScript

public void appendExpressionToScript(EOSQLExpression expression,
                                     StringBuffer script)

Description copied from class: EOSynchronizationFactory

Appends expression's statement to script along with any necessary delimiter. script is the StringBuffer in which the SQL script is built. Used in conjunction with schemaCreationStatementsForEntities and schemaCreationScriptForEntities to build up the SQL script to generate the specified schema for a set of EOEntities.

This method appends the SQL statement for expression to script followed by a semicolon and a newline. A subclass of EOSQLExpression only need to override this method if the delimiter for its database server is different.

Overrides:

appendExpressionToScript in class EOSynchronizationFactory

Following copied from class: com.webobjects.eoaccess.EOSynchronizationFactory

Parameters:

expression - An EOSQLExpression.

script - A StringBuffer used to build the SQL script.

EOSynchronizationFactory.createTableStatementsForEntityGroup( NSArray entityGroup)

createDatabaseStatementsForConnectionDictionary

public NSArray createDatabaseStatementsForConnectionDictionary(NSDictionary connectionDictionary,
                                                               NSDictionary administrativeConnectionDictionary)

Description copied from class: EOSynchronizationFactory

The default implementation returns null. Can be overridden by subclasses to generate and return an array of EOSQLExpressions defining the SQL statements to create a database or user that can be accessed by the provided connectionDictionary and administrativeConnectionDictionary.

Overrides:

createDatabaseStatementsForConnectionDictionary in class EOSynchronizationFactory

Following copied from class: com.webobjects.eoaccess.EOSynchronizationFactory

Parameters:

connectionDictionary - A dictionary of information needed by the adaptor to connect to the database server.

administrativeConnectionDictionary - A dictionary of administrative login information for the database server.

Returns:

null by default.

See Also:

EOSynchronizationFactory.dropDatabaseStatementsForConnectionDictionary( NSDictionary connectionDictionary, NSDictionary administrativeConnectionDictionary)

dropDatabaseStatementsForConnectionDictionary

public NSArray dropDatabaseStatementsForConnectionDictionary(NSDictionary connectionDictionary,
                                                             NSDictionary administrativeConnectionDictionary)

Description copied from class: EOSynchronizationFactory

The default implementation returns null. Can be overridden by subclasses to generate and return an array of EOSQLExpressions defining the SQL statements to drop a database or user that is accessed by the provided connectionDictionary and administrativeConnectionDictionary.

Overrides:

dropDatabaseStatementsForConnectionDictionary in class EOSynchronizationFactory

Following copied from class: com.webobjects.eoaccess.EOSynchronizationFactory

Parameters:

connectionDictionary - A dictionary of information needed by the adaptor to connect to the database server.

administrativeConnectionDictionary - A dictionary of administrative login information for the database server.

Returns:

null by default.

See Also:

EOSynchronizationFactory.createDatabaseStatementsForConnectionDictionary( NSDictionary connectionDictionary, NSDictionary administrativeConnectionDictionary)

dropPrimaryKeySupportStatementsForEntityGroup

public NSArray dropPrimaryKeySupportStatementsForEntityGroup(NSArray entityGroup)

Description copied from class: EOSynchronizationFactory

The default implementation returns null. Can be overridden by subclasses to return an array of EOSQLExpression objects that define the SQL necessary to drop the primary key generation support for entityGroup.

Overrides:

dropPrimaryKeySupportStatementsForEntityGroup in class EOSynchronizationFactory

Following copied from class: com.webobjects.eoaccess.EOSynchronizationFactory

Parameters:

entityGroup - An array of EOEntity objects that have the same external name.

Returns:

null by default.

See Also:

EOSynchronizationFactory.primaryKeySupportStatementsForEntityGroup( NSArray entityGroup), EOEntity.externalName()

dropTableStatementsForEntityGroup

public NSArray dropTableStatementsForEntityGroup(NSArray entityGroup)

Description copied from class: EOSynchronizationFactory

Returns an array of EOSQLExpression objects that define the SQL necessary to drop the table identified by entityGroup. Returns an empty array if entityGroup is null. The drop statement generated by this method should be sufficient to remove the table created by createTableStatementsForEntityGroup's statements.

This method creates a statement of the form:

             DROP TABLE TABLE_NAME
 

where TABLE_NAME is the external name of the first entity in entityGroup.

If the database server's drop semantics are different, a subclass should override this method.

Overrides:

dropTableStatementsForEntityGroup in class EOSynchronizationFactory

Following copied from class: com.webobjects.eoaccess.EOSynchronizationFactory

Parameters:

entityGroup - An array of EOEntity objects that have the same external name.

Returns:

An array of EOSQLExpressions that define the SQL necessary to drop tables for the entities in entityGroup, or an empty array.

See Also:

EOSynchronizationFactory.createTableStatementsForEntityGroup( NSArray entityGroup), EOEntity.externalName()

primaryKeySupportStatementsForEntityGroup

public NSArray primaryKeySupportStatementsForEntityGroup(NSArray entityGroup)

Description copied from class: EOSynchronizationFactory

The default implementation returns null. Can be overridden by subclasses to return an array of EOSQLExpression objects that define the SQL necessary to create the primary key generation support for entityGroup.

Overrides:

primaryKeySupportStatementsForEntityGroup in class EOSynchronizationFactory

Following copied from class: com.webobjects.eoaccess.EOSynchronizationFactory

Parameters:

entityGroup - An array of EOEntity objects that have the same external name.

Returns:

null by default.

See Also:

EOSynchronizationFactory.dropPrimaryKeySupportStatementsForEntityGroup( NSArray entityGroup), EOAdaptorChannel.primaryKeyForNewRowWithEntity( EOEntity entity), EOEntity.externalName()

supportsSchemaSynchronization

public boolean supportsSchemaSynchronization()

Description copied from class: EOSynchronizationFactory

The default implementation returns false. Can be overridden by subclasses to return true if the adaptor can update the database schema to reflect changes in an EOModel.

Overrides:

supportsSchemaSynchronization in class EOSynchronizationFactory

Following copied from class: com.webobjects.eoaccess.EOSynchronizationFactory

Returns:

true if the adaptor can update the database schema.
