Class::Default 1.51

Class::Default - static calls apply to a default instantiation.

SYNOPSIS

# Create the defaulted class
package Foo::Base;

use base 'Class::Default';

sub new { bless {}, $_[0] }

sub show {
my $self = shift->_self;
"$self";
}

# Do something to the default object

package main;

print Foo::Bar->show;

# Prints 'Foo::Bar=HASH(0x80d22f8)'

Class::Default provides a mechanism to allow your class to take static method calls and apply it to a default instantiation of an object. It provides a flexibility to an API that allows it to be used more confortably in different situations.

A good example of this technique in use is CGI.pm. When you use a static method, like CGI-header>, your call is being applied to a default instantiation of a CGI object.

This technique appears to be especially usefull when writing modules that you want to be used in either a single use or a persistant environment. In a CGI like environment, you want the simplicity of a static interface. You can call Class-method> directly, without having to pass an instantiation around constantly.
