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
