NAME
Rose::DB::Object::Metadata::Column::Scalar - Scalar column metadata.SYNOPSIS
use Rose::DB::Object::Metadata::Column::Scalar; $col = Rose::DB::Object::Metadata::Column::Scalar->new(...); $col->make_methods(...); ...
DESCRIPTION
Objects of this class store and manipulate metadata for scalar 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. 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.
METHOD MAP
- "get_set"
- Rose::DB::Object::MakeMethods::Generic, scalar, "interface => 'get_set', ..."
- "get"
- Rose::DB::Object::MakeMethods::Generic, scalar, "interface => 'get', ..."
- "get_set"
- Rose::DB::Object::MakeMethods::Generic, scalar, "interface => 'set', ..."
See the Rose::DB::Object::Metadata::Column documentation for an explanation of this method map.
OBJECT METHODS
- check_in [ARRAYREF]
- Get or set a reference to an array of valid column values.
- default VALUE
- Get or set the default value for the column.
- init_method [NAME]
- Get or set the name of the ``init'' method. See the documentation for the "scalar" method type in Rose::DB::Object::MakeMethods::Generic for more information.
- length [INT]
- Get or set the length of the column in characters.
- overflow [BEHAVIOR]
- Get or set the setting that determines the behavior when the column value is greater than length characters. Valid values for BEHAVIOR are:
-
- fatal
- Throw an exception.
- truncate
- Truncate the column value to the correct length.
- warn
- Print a warning message.
The default value is ``fatal''.
-
- type
- Returns ``scalar''.
- with_init [BOOL]
- Get or set the flag that determines whether or not the method created by "make_method()" will include an ``init'' method as well. See the documentation for the scalar method type in Rose::DB::Object::MakeMethods::Generic for more information.
