NAME

Class::Simple::Readonly::Cached - cache messages to an object

VERSION

Version 0.01

SYNOPSIS

A sub-class of Class::Simple which caches calls to read the status of an object that are otherwise expensive.

It is up to the caller to maintain the cache if the object comes out of sync with the cache, for example by changing its state.

Note that it only works on objects which doesn't change its state based on input

    $val = $obj->val();
    $val = $obj->val(a => 'b');

SUBROUTINES/METHODS

new

Creates a Class::Simple::Readonly::Cached object.

It takes one mandatory parameter: cache, which is an object which understands get() and set() calls, such as an CHI object.

It takes one optional argument: object, which is an object which is taken to be the object to be cached. If not given, an object of the class Class::Simple is instantiated and that is used.

BUGS

Doesn't work with Memoize.

Please report any bugs or feature requests to bug-class-simple-readonly-cached at rt.cpan.org, or through the web interface at http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Class-Simple-Readonly-Cached. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.

params() returns a ref which means that calling routines can change the hash for other routines. Take a local copy before making amendments to the table if you don't want unexpected things to happen.
