=head1 NAME
KiokuDB::TypeMap::Entry::Naive - A typemap entry for "simple" objects
=head1 VERSION
version 0.57
=head1 SYNOPSIS
KiokuDB::TypeMap->new(
entires => {
'My::Class' => KiokuDB::TypeMap::Entry::Naive->new,
},
);
=head1 DESCRIPTION
This typemap entry is suitable for plain objects that can be stored by simply
walking them recursively.
Most objects fall into this category, but there are notable exceptions:
=over 4
=item XS based objects, using a pointer as a number
When being deserialized the pointer value will no longer be valid, causing
segfaults.
=item Inside out objects
Since the referent is really a flyweight object with no data, the object will
be missing its attributes and a suitable typemap entry is required instead.
This applies to any object interacting with a global state of some sort.
=item Objects with magic
Perl SV level magic is not retained, apart from tied values.
=back
=head1 ATTRIBUTES
=over 4
=item intrinsic
If true the object will be collapsed without an ID as part of its parent.
