Set::Object::Weak(3pm)
NAME
Set::Object::Weak - Sets without the referant reference increment
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
Sets, but weak. See "weaken" in Set::Object.
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.
