NAME

SYNOPSIS

 use Set::Object::Weak qw(weak_set);

 my $set = Set::Object::Weak->new( 0, "", {}, [], $object );
 # or
 my $set = weak_set( 0, "", {}, [], $object );

 print $set->size;  # 2 - the scalars aren't objects

DESCRIPTION

Note that the "set" in "Set::Object::Weak" returns weak sets. This is intentional, so that you can make all the sets in scope weak just by changing "use Set::Object" to "use Set::Object::Weak".

CONSTRUCTORS

new

This class method is exactly the same as "Set::Object->new", except that it returns a weak set.

weak_set( ... )

This optionally exported function is a shortcut for saying "Set::Object::Weak->new(...)".

set( ... )

This method is exported so that if you see:

 use Set::Object qw(set);
    

You can turn it into using weak sets lexically with:

 use Set::Object::Weak qw(set);
    

Set::Object 1.19 had a bug in this method that meant that it would not add the passed members into it.
