Rose::DB::Object::Metadata::Column::Scalar(3pm)

Rose::DB::Object::Metadata::Column::Scalar3pm

Scalar column metadata.

Usage

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

Overview

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.

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.
