NAME

Top

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

SYNOPSIS

Top

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

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

DESCRIPTION

Top

Objects of this class store and manipulate metadata for array 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

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

OBJECT METHODS

Top

dimensions [ARRAYREF]

Get or set the dimensions of the column as a reference to an array of integer dimensions.
