TextColumn represents a table column that contains a text or String value. All database table column text or String classes should subclass this Column class.

The specified text column length determines the database table column type. If the column length is less than 16 characters, the database table column type will be DataType.CHAR. Otherwise, the database table column type will be DataType.VARCHAR
