NAME

Data::Hive::PathPacker - a thing that converts paths to strings and then back

VERSION

version 1.015

DESCRIPTION

Data::Hive::PathPacker classes are used by some Data::Hive::Store classes to convert hive paths to strings so that deep hives can be stored in flat storage.

Path packers must implement two methods:

PERL VERSION

This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.

METHODS

pack_path

my $str = $packer->pack_path( \@path );

This method is passed an arrayref of path parts and returns a string to be used as a key in flat storage for the path.

unpack_path

my $path_arrayref = $packer->unpack_path( $str );

This method is passed a string and returns an arrayref of path parts represented by the string.
