NAME

Rose::DB::Object::Metadata::Column::Blob - Binary large object column metadata.

SYNOPSIS

Top

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

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

DESCRIPTION

Top

Objects of this class store and manipulate metadata for long, variable-length character-based 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::Character. Inherited methods that are not overridden will not be documented a second time here. See the Rose::DB::Object::Metadata::Column::Character documentation for more information.
