NAME

Top

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

SYNOPSIS

Top

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

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

DESCRIPTION

Top

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

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

METHOD MAP

get_set

Rose::DB::Object::MakeMethods::Generic, boolean, ...

get

Rose::DB::Object::MakeMethods::Generic, boolean, ...

get_set

Rose::DB::Object::MakeMethods::Generic, boolean, ...

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

OBJECT METHODS

Top

parse_value DB, VALUE

Parse VALUE and return true or false according to how the underlying database would view VALUE as the value for a boolean column. DB is a Rose::DB object that is used as part of the parsing process. Both arguments are required.
