NAME

App::MathImage::NumSeq::Sequence -- base class for various number sequences

SYNOPSIS

# only a base class, use one of the actual classes such as
use App::MathImage::NumSeq::Sequence::Squares;
my $seq = App::MathImage::NumSeq::Sequence::Squares->new;
my ($i, $square) = $seq->next;

DESCRIPTION

This is a base class for number sequences.

FUNCTIONS

The following is a

$seq = App::MathImage::NumSeq::Sequence::Foo->new (key=>value,...)

Create and return a new sequence object.

($i, $value) = $seq->next()

Return the next index and value in the sequence.

$seq->rewind()

Return the sequence to its starting point.

Optional Methods

The following methods are only implemented for some sequence classes.

$value = $seq->ith($i)

Return the $i'th value in the sequence. Only some sequence classes implement this method.

$bool = $seq->pred($value)

Return true if $value occurs in the sequence. For example for the squares this would return true if $value is a perfect square and false if not.
