NAME

       KiokuDB::TypeMap::Shadow - Try a list of KiokuDB::TypeMaps in order

VERSION

       version 0.57

SYNOPSIS

           KiokuDB->new(
               backend => ...,
               typemap => KiokuDB::TypeMap::Shadow->new(
                   typemaps => [
                       $first,
                       $second,
                   ],
               ),
           );

DESCRIPTION

       This class is useful for performing mixin inheritance like merging of typemaps, by
       shadowing an ordered list.

       This is used internally to overlay the user typemap on top of the
       KiokuDB::TypeMap::Default instance provided by the backend.

       This differs from using "includes" in KiokuDB::TypeMap because that inclusion is computed
       symmetrically, like roles.
