Class::PublicPrivate - Class with public keys with any name and a separate set of private keys


PublicPrivate is intended for use as a base class for other classes. Users of class based on PublicPrivate can assign any keys to the object hash without interfering with keys used internally. The private data can be accessed by retrieving the private hash with the private method. For example, the following code outputs two different values, one for the public value of start and another for the private value of start.

 package ExtendedClass;
 use base 'Class::PublicPrivate';

 sub new{
    my $class = shift;
    my $self = $class->SUPER::new();
    my $private = $self->private;

    # initialize one of the private properties

    return $self;

 package main;
 my ($var);
 $var = ExtendedClass->new();
 $var->{'start'} = 1;

 print $var->{'start'}, "\n";
 print $var->private()->{'start'}, "\n";


Class::PublicPrivate can be installed with the usual routine:

 perl Makefile.PL
 make test
 make install


YourClass->new(classname ,[initikey1=>initvalue [, ...]])

Returns an instantiation of YourClass, where YourClass is a class that extends Class::PublicPrivate. Additional key=>value pairs are stored in the private hash. Programs that use your class can store any date directly in it w/o affecting the object's private data.


Returns a reference to the hash of private data.
