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

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


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

Important note: if you are using MySQL 5.0.3 or later, you must allow inline column values in any the Rose::DB::Object manpage-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 the Rose::DB manpage object that is used as part of the parsing process. Both arguments are required.

type
Returns ``bitfield''.
