                                             boolean indexesForPrimaryKeys,
                                             boolean indexesForForeignKeys)

Convenience method: build an options dictionary from the arguments specified.

Parameters:

createTables - SQL should be generated to build database tables.

dropTables - SQL should be generated to drop database tables.

createPrimaryKeySupport - SQL should be generated to create primary key support.

dropPrimaryKeySupport - SQL should be generated to drop primary key support.

primaryKeyConstraints - SQL should be generated to create primary key constraints.

foreignKeyConstraints - SQL should be generated to create foreign key support.

indexesForPrimaryKeys - This parameter is currently ignored by EOF.

indexesForForeignKeys - This parameter is currently ignored by EOF.

Returns:

The resulting dictionary.
