Constructor Detail

MicrosoftPlugIn.MicrosoftSynchronizationFactory

public MicrosoftPlugIn.MicrosoftSynchronizationFactory(EOAdaptor adaptor)
Method Detail

primaryKeySupportStatementsForEntityGroups

public NSArray primaryKeySupportStatementsForEntityGroups(NSArray entityGroups)
Description copied from class: EOSchemaSynchronizationFactory
Returns an array of EOSQLExpression objects that define the SQL necessary to create the primary key generation support for all the entities in each of the the entity groups in entityGroups. Returns an empty array if entityGroups is null or empty. If primary key generation is not supported, returns an array that contains the string "The 'Create Primary Key Support' option is unavailable."

This method invokes primaryKeySupportStatementsForEntityGroup for each entity group in entityGroups and returns an array of all the resulting EOSQLExpressions. Since the default implementation of primaryKeySupportStatementsForEntityGroup returns null, this method returns the "not supported" value (see above) by default, but a subclass need only override primaryKeySupportStatementsForEntityGroup in order to enable this method as well.

Specified by:
primaryKeySupportStatementsForEntityGroups in interface EOSchemaGeneration
Overrides:
primaryKeySupportStatementsForEntityGroups in class EOSchemaSynchronizationFactory
Parameters:
entityGroups - An NSArray of entity groups, which are arrays of EOEntity objects that have the same external name.
Returns:
An array of EOSQLExpressions that define the SQL necessary to create primary key generation support for entityGroups, or an empty array, or an array containing a string message that the option is not supported.
See Also:
EOSchemaSynchronizationFactory.primaryKeySupportStatementsForEntityGroup( NSArray entityGroup), EOAdaptorChannel.primaryKeyForNewRowWithEntity( EOEntity entity), EOEntity.externalName()

dropPrimaryKeySupportStatementsForEntityGroups

public NSArray dropPrimaryKeySupportStatementsForEntityGroups(NSArray entityGroups)
Description copied from class: EOSchemaSynchronizationFactory
Returns an array of EOSQLExpression objects that define the SQL necessary to drop the primary key generation support for all the entities in each of the the entity groups in entityGroups. Returns an empty array if entityGroups is null or empty. If primary key generation is not supported, returns an array that contains the string "The 'Drop Primary Key Support' option is unavailable."

This method invokes dropPrimaryKeySupportStatementsForEntityGroup for each entity group in entityGroups and returns an array of all the resulting EOSQLExpressions. Since the default implementation of dropPrimaryKeySupportStatementsForEntityGroup returns null, this method returns the "not supported" value (see above) by default, but a subclass need only override dropPrimaryKeySupportStatementsForEntityGroup in order to enable this method as well.

Specified by:
dropPrimaryKeySupportStatementsForEntityGroups in interface EOSchemaGeneration
Overrides:
dropPrimaryKeySupportStatementsForEntityGroups in class EOSchemaSynchronizationFactory
Parameters:
entityGroups - An NSArray of entity groups, which are arrays of EOEntity objects that have the same external name.
Returns:
An array of EOSQLExpressions that define the SQL necessary to drop primary key generation support for entityGroups, or an empty array, or an array containing a string message that the option is not supported.
See Also:
EOSchemaSynchronizationFactory.dropPrimaryKeySupportStatementsForEntityGroup( NSArray entityGroup), #schemaCreationStatementsForEntities( NSArray allEntities, NSDictionary options), EOAdaptorChannel.primaryKeyForNewRowWithEntity( EOEntity entity), EOEntity.externalName()

dropTableStatementsForEntityGroup

public NSArray dropTableStatementsForEntityGroup(NSArray entityGroup)
Description copied from class: EOSchemaSynchronizationFactory
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.

Specified by:
dropTableStatementsForEntityGroup in interface EOSchemaGeneration
Overrides:
dropTableStatementsForEntityGroup in class EOSchemaSynchronizationFactory
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:
EOSchemaSynchronizationFactory.createTableStatementsForEntityGroup( NSArray entityGroup), EOEntity.externalName()

supportsSchemaSynchronization

public boolean supportsSchemaSynchronization()
Description copied from class: EOSchemaSynchronizationFactory
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.

Specified by:
supportsSchemaSynchronization in interface EOSchemaSynchronization
Overrides:
supportsSchemaSynchronization in class EOSchemaSynchronizationFactory
Returns:
true if the adaptor can update the database schema.

statementsToRenameTableNamed

public NSArray statementsToRenameTableNamed(String tableName,
                                            String newName,
                                            EOSchemaGenerationOptions options)
Description copied from interface: EOSchemaSynchronization
Returns an array of EOSQLExpressions to rename in place the the table indentifed by tableName to newName. options is a dictionary describing the aspects of the schema for which to create SQL statements.

Specified by:
statementsToRenameTableNamed in interface EOSchemaSynchronization
Overrides:
statementsToRenameTableNamed in class EOSchemaSynchronizationFactory
Parameters:
tableName - The name of a table to be renamed.
newName - The new name for the specified table.
options - A dictionary describing the aspects of the schema for which to create SQL statements.
Returns:
An array of the EOSQLExpressions to rename in place the specified table.
