Array::AsHash::Iterator
Iterator object for L<Array::AsHash>

Array::AsHash::Iterator - Iterator object for L<Array::AsHash>


NAME

Array::AsHash::Iterator - Iterator object for the Array::AsHash manpage


VERSION

Version 0.02


SYNOPSIS


    my $iterator = Array::AsHash->new({array => \@array})->each;

    while (my ($key, $value) = $iterator->next) {

        print "First \n" if $iterator->first;

        print "$key : $value\n";

        print "Last \n" if $iterator->last;

    }


DESCRIPTION

This is the iterator returned by the Array::AsHash::each method. Do not use directly.


EXPORT

None.


METHODS

new


 my $iterator = Array::AsHash::Iterator->new({

     parent => $array_as_hash_object,

     iterator => $array_as_hash_object_internal_iterator,

 });

next


  while (my ($key, $value) = $iterator->next) {

    ...

  }

Returns the next key/value pair in the iterator.

first


  if ($iterator->first) {

    ...

  }

Returns true after when we are on the first key/value pair (after it has been returned) and before we have returned the second key/value pair.

last


  if ($iterator->last) {

    ...

  }

Returns true after we have returned the last key/value pair.

parent


 my $parent = $iterator->parent;

Returns the parent the Array::AsHash manpage object used to create the iterator.

reset_each


 $iterator->reset_each;

As with a regular hash, if you do not iterate over all of the data, the internal pointer will be pointing at the next key/value pair to be returned. If you need to restart from the beginning, call the reset_each method.
