Rose::DB::Object::Metadata::Column::Bitfield - Bitfield column metadata.
use Rose::DB::Object::Metadata::Column::Bitfield; $col = Rose::DB::Object::Metadata::Column::Bitfield->new(...); $col->make_methods(...); ...
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.
BIT
get_set
Rose::DB::Object::MakeMethods::Generic, bitfield, ...
get
See the Rose::DB::Object::Metadata::Column documentation for an explanation of this method map.
Get or set the number of bits in the column.
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.
Bit::Vector
bits()
Returns "bitfield".
