VERSION

version 1.00

ABSTRACT

Multi-threaded base class to establish a class deriving relationship with base classes at compile time

package Foo;
use Object::Base;
attributes ':shared', 'attr1', 'attr2';

package Bar;
use Object::Base 'Foo';
attributes 'attr3', ':shared' => undef, 'attr2' => undef;

package main;
use threads;
use threads::shared;

# object of Foo
my $foo = Foo->new();

# usage of attribute
$foo->attr1(1);
print $foo->attr1, "\n"; # prints '1'

# attributes are also lvaluable
$foo->attr1++;
print $foo->attr1, "\n"; # prints '2'

# class attributes, eg: ':shared'
print "\$foo is ", is_shared($foo)? "shared": "not shared", "\n";

# object of derived class Bar
my $bar = Bar->new();

# attributes can be added derived classes
$bar->attr3(3);

# attributes are inheritable
$bar->attr1(3);

# attributes are overridable #1
eval { $bar->attr2 = 4 }; print $@; # prints error 'Attribute attr2 is not defined in Bar at ...'

# attributes are overridable #2
print "\$bar is ", is_shared($bar)? "shared": "not shared", "\n"; # prints '$bar is not shared'

# assigning ref values to shared class attributes
eval { $foo->attr2 = { key1 => 'val1' } }; print $@; # prints error 'Invalid value for shared scalar at ...'
$foo->attr2({ key2 => 'val2' }); # uses shared_clone assigning ref value
