NAME

EO::WeakArray - arrays where all references contained are weak

SYNOPSIS

  use EO::WeakArray;
  my $thing = {};
  my $array = EO::WeakArray->new;
  $array->push( $obj );
  $obj = undef;

  if ( $array->at( 0 ) == undef ) {
    print "ok\n";
  }

DESCRIPTION

A WeakArray is similar to a normal array only its contents are not reference counted. Thus, if something destroys the contents from the outside world then it disappears from inside the array as well.

METHODS

WeakArrays provide no methods beyond those provided by an array.
