Hash-Iterator version 0.02 ========================== **INSTALLATION** To install this module type the following: perl Makefile.PL make make test make install _cpan_ sudo perl -MCPAN -e shel cpan> install Hash::Iterator cpan install Hash::Iterator **NAME** Hash::Iterator - Hashtable Iterator. **SYNOPSIS** my $iterator = Hash::Iterator->new( map { $_ => uc $_ } 'a'..'z' ); while ($iterator->next) { say sprintf("%s => %s", $iterator->peek_key, $iterator->peek_value); } my $iterator = Hash::Iterator->new( a => [qw(one two three)] ); $iterator->next; if ( $iterator->is_ref('ARRAY') ) { foreach my $item ( @{$iterator->peek_value} ) { say $item; } } **DESCRIPTION** _CONSTRUCTORS_ _new_ my $iterator = Hash::Iterator->new( %hash ); Return a Hash::Iterator for C **METHODS** _next_ $iterator->next; Advance the iterator to the next key-value pair _previous_ $iterator->previous; Advance the iterator to the previous key-value pair _done_ do { .... } while ($iterator->done); Returns a boolean value if the iterator was exhausted _peek_key_ say $iterator->peek_key; Return the key of the current key-value pair. It's not allowed to call this method before L was called for the first time or after the iterator was exhausted. _peek_value_ say $iterator->peek_value; Return the value of the current key-value pair. It's not allowed to call this method before L was called for the first time or after the iterator was exhausted. _is_ref_ if ( $iterator->is_ref('ARRAY') ) { ... } Returns a boolean value if value is a reference. _get_keys_ my @keys = $iterator->get_keys; Returns a list of all keys from hash **AUTHOR** vlad mirkos, Evladmirkos@sd.apple.comE **COPYRIGHT AND LICENSE** Copyright (C) 2017 by vlad mirkos This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself, either Perl version 5.18.2 or, at your option, any later version of Perl 5 you may have available.
