KiokuDB::TypeMap::Entry(3)

NAME
KiokuDB::TypeMap::Entry - Role for KiokuDB::TypeMap entries

SYNOPSIS
    package KiokuDB::TypeMap::Foo;
    use Moose;

    with qw(KiokuDB::TypeMap::Entry);

    # or just use KiokuDB::TypeMap::Entry::Std

    sub compile {
        ...
    }

DESCRIPTION
This is the role consumed by all typemap entries.

REQUIRED METHODS

compile $class
    This method is called by KiokuDB::TypeMap::Resolver for a given class, and should return two code references, one for collapsing and one for expanding.

    The collapsing sub is called as a method on KiokuDB::Collapser and the expanding sub is called on KiokuDB::Linker.

    The callbacks must call other KiokuDB::Collapser and KiokuDB::Linker methods to actually get the work done.

    KiokuDB::TypeMap::Entry::Std provides a more concise way of defining typemap entries.
