74 MooseX::Storage::Util - A MooseX::Storage Swiss Army chainsaw
78 This module provides a set of tools, some sharp and focused,
79 others more blunt and crude. But no matter what, they are useful
80 bits to have around when dealing with MooseX::Storage code.
84 All the methods in this package are class methods and should
85 be called appropriately.
89 =item B<peek ($data, %options)>
91 This method will help you to verify that the serialized class you
92 have gotten is what you expect it to be before you actually
95 The C<$data> can be either a perl HASH ref or some kind of serialized
96 data (JSON, YAML, etc.).
98 The C<%options> are as follows:
104 If this is left blank, we assume that C<$data> is a plain perl HASH ref
105 otherwise we attempt to inflate C<$data> based on the value of this option.
107 Currently only JSON and YAML are supported here.
111 The default is to try and extract the class name, but if you want to check
112 another key in the data, you can set this option. It will return the value
113 found in the key for you.
131 Add more stuff to this module :)
135 All complex software has bugs lurking in it, and this module is no
136 exception. If you find a bug please either email me, or add the bug
