MooseX::Role::Hashable - Transform the object into a hash


Version 1.04


This module adds a single method to an object to convert it into a simple hash. This is meant to act as the inverse function of new, provided nothing too crazy is going on during initialization. If the class is made immutable, the optimizer will precalculate the extracted attributes for a signifcant speed up.

Example usage:

        package Foo;
        use Moose;
        use MooseX::Role::Hashable;

        has field1 => (is => 'rw');
        has field2 => (is => 'ro');
        has field3 => (is => 'bare');
        has _field4 => (is => 'rw', init_arg => 'field4');


        package main;

        my $foo = Foo->new(field1 => 'val1', field2 => 'val2', field3 => 'val3', field4 => 'val4');
        # => {field1 => 'val1', field2 => 'val2', field3 => 'val3', field4 => 'val4'}



Transform the object into a hash of attribute-value pairs. All attributes, including those without a reader, are extracted. Attributes whose initial arguments differ from their name will appear using the initialization argument. Attributes which can' be initialized will be ignored. Reference values will perform a shallow copy.
