NAME

Algorithm::GenerateSequence - a sequence generator

SYNOPSIS

 my $gen = Algorithm::GenerateSequence->new(
    [qw( one two three )], [qw( hey bee )],
 );
 print join(' ', $gen->next), "\n"; # one hey
 print join(' ', $gen->next), "\n"; # one bee
 print join(' ', $gen->next), "\n"; # two hey
 print join(' ', $gen->next), "\n"; # two bee
 ...

DESCRIPTION

Algorithm::GenerateSequence provides an iterator interface to a sequence you define in terms of the symbols to use in each position.

You may use a different amount of symbols in each position and the module will iterate over them correctly. This might be useful in identifying all the cards in a deck:

 my $deck = Algorithm::GenerateSequence->new(
     [qw( Heart Diamond Spade Club )],
     [qw( A 2 3 4 5 6 7 8 9 10 J Q K )],
 );

Or for a range of addresses to scan:

 my $scan = Algorithm::GenerateSequence->new(
     [192], [168], [0..254], [1]
 );

METHODS

new( @values );

@values contains arrays of symbols which will be used to form the sequence

next

returns a list containing the next value in the sequence, or false if at the end of the sequence

as_list

return the remainder of the sequence as a list of array references

BUGS

None currently known. If you find any please make use of http://rt.cpan.org by mailing your report to bug-Algorithm-GenerateSequence@rt.cpan.org, or contact me directly.
