SYNOPSIS

        package foo;
        use Meta::Ds::Oset qw();
        my($oset)=Meta::Ds::Oset->new();
        $oset->insert("mark");

DESCRIPTION

This is a set object which is also ordered. This means you can access the n'th element. You get performance penalties in this implementation (especially upon removal of elements) so if you dont need the ordered feature please use the Meta::Ds::Set class.

FUNCTIONS

        new($)
        insert($$)
        remove($$)
        has($$)
        hasnt($$)

        elem($$)
        sort($$)

has($$)

hasnt($$)

This returns whether a specific element is not a member of the set.

check_elem($$)

Thie method receives: 0. An Oset object. 1. An element to check fore. This method makes sure that the element is a member of the set and dies if it is not.

check_not_elem($$)

Thie method receives: 0. An Oset object. 1. An element to check fore. This method makes sure that the element is a member of the set and dies if it is not.

print($$)

This will print the Oset object to the specified file for you.

size($)

This method returns the size of the set.

elem($$)

This method receives: 0. An Oset object. 1. A location. And retrieves the element at that location.
