NAME

       Rose::DB::Object::Metadata::Column::Bitfield - Bitfield column metadata.

SYNOPSIS

         use Rose::DB::Object::Metadata::Column::Bitfield;

         $col = Rose::DB::Object::Metadata::Column::Bitfield->new(...);
         $col->make_methods(...);
         ...

DESCRIPTION

       Objects of this class store and manipulate metadata for bitfield columns in a database.
       Column metadata objects store information about columns (data type, size, etc.) and are
       responsible for parsing, formatting, and creating object methods that manipulate column
       values.

       This class inherits from Rose::DB::Object::Metadata::Column. Inherited methods that are
       not overridden will not be documented a second time here.  See the
       Rose::DB::Object::Metadata::Column documentation for more information.

       Important note: if you are using MySQL 5.0.3 or later, you must allow inline column values
       in any Rose::DB::Object-derived class that has one or more bitfield columns.  (That is,
       columns that use the "BIT" data type.)  This requirement may be relaxed in the future.

METHOD MAP

       "get_set"
           Rose::DB::Object::MakeMethods::Generic, bitfield, ...

       "get"
           Rose::DB::Object::MakeMethods::Generic, bitfield, ...

       "get_set"
           Rose::DB::Object::MakeMethods::Generic, bitfield, ...

       See the Rose::DB::Object::Metadata::Column documentation for an explanation of this method
       map.

OBJECT METHODS

       bits [INT]
           Get or set the number of bits in the column.

       parse_value DB, VALUE
           Convert VALUE to the equivalent "Bit::Vector" object.  The return value of the column
           object's "bits()" method is used to determine the length of the bitfield in bits.  DB
           is a Rose::DB object that is used as part of the parsing process.  Both arguments are
           required.

       type
           Returns "bitfield".
