NAME

KiokuDB::TypeMap - Class to collapsing/expanding logic.

VERSION

version 0.57

SYNOPSIS

    use KiokuDB::TypeMap;
    KiokuDB::TypeMap->new(
        entries => {
            'Foo' => KiokuDB::TypeMap::Entry::Naive->new,
        },
        isa_entries => {
            'My::Class' => KiokuDB::TypeMap::Entry::Naive->new,
        },
        includes => [
            $typemap_foo,
            $typemap_bar,
        ],
    );

DESCRIPTION

The KiokuDB typemap maps classes to KiokuDB::TypeMap::Entry objects.

The mapping is by class, and entries can be keyed normally (using "ref $object" equality) or by filtering on "$object->isa($class)" ("isa_entries").

ATTRIBUTES

entries: A hash of normal entries.
isa_entries: A hash of "$object->isa" based entries.
includes: A list of parent typemaps to inherit entries from.

METHODS

resolve $class: Given a class returns the "KiokuDB::TypeMap::Entry" object corresponding to that class.
Called by KiokuDB::TypeMap::Resolver
resolve_entry $entry: If the entry is an alias, it will be resolved recursively, and simply returned otherwise.
all_entries: Returns the merged "entries" from this typemap and all the included typemaps.
all_isa_entries: Returns the merged "isa_entries" from this typemap and all the included typemaps.
all_isa_entry_classes: An array reference of all the classes in "all_isa_entries", sorted from least derived to most derived.
