Overview

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

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".
