NAME

Lingua::ZH::CCDICT::Storage::BerkeleyDB - Store the dictionary in BerkeleyDB files

USAGE

  use Lingua::ZH::CCDICT;

  my $dict = Lingua::ZH::CCDICT->new( storage  => 'BerkeleyDB',
                                      work_dir => '/path/to/work/dir',
                                    );

DESCRIPTION

This module stores the CCDICT dictionary in a set of BerkeleyDB files. There is one file for the data and a number of other files used as indexes.

This storage implementation is quite fast and uses very little memory.

The only parameter it takes is "work_dir". This directory will be used when creating new files from a CCDICT source file, when parse_source_file() is called. Once these files exist, they can be re-used for future searches without parsing the source again.

This class is the most memory-efficient of all the storage classes, as it uses BerkeleyDB cursors for result sets. It is also quite fast.

METHODS

This class offers only one method not documented in the Lingua::ZH::CCDICT class.

$dict->files()

This returns a list of the files that make up the dictionary. This list includes files automatically created by BerkeleyDB for its own use.
