=head1 NAME
KiokuDB::TypeMap::Resolver - Caching resolver for KiokuDB::TypeMap
=head1 VERSION
version 0.57
=head1 SYNOPSIS
This object is used by L<KiokuDB::Linker> and L<KiokuDB::Collapser> to map
class names to collapsing/expanding method bodies.
Since L<KiokuDB::TypeMap>s are fairly complex, and L<KiokuDB::TypeMap::Entry>
objects can benefit from specializing to a class by precomputing some things,
resolution is performed once per class, and the results are cached in the
resolver.
