NAME

Games::Go::Rank - represents a player's rank in the game of Go

SYNOPSIS

    use Games::Go::Rank;

    my $black_rank = Games::Go::Rank->new(rank => '1k');
    my $white_rank = Games::Go::Rank->new(rank => '2d');
    if ($white_rank > $black_rank) { ... }

DESCRIPTION

This class represents a player's rank in the game of Go. Rank objects can be compared to see whether two ranks are equal or whether one rank is higher than the other. Rank objects stringify to the rank notation.

METHODS

Additionally, this class defines the following methods:

rank

Sets or gets the rank. Use the standard notation for ranks such as 30k, 5k, 1d, 2p and so on. You can also use other common formats such as 6-dan or 2 dan. Anything after the first k, d or p is ignored. So 6-dan* is the same as 6-dan, which is the same as 6d.

clear_rank

Clears the rank.

as_value

Returns a number representing the rank. 1k is returned as 0, lower kyu ranks are returned as negative numbers (2K is -1, 3k is -2 etc.). Dan ranks are returned as positive numbers, with pro ranks coming immediately after dan ranks. For example, 1d == 1, 7d == 7, 1p == 8, 2p == 9. Only dan ranks up to 7d are recognized as amateur ranks - that is, 8d == 1p.

from_value

Sets the rank from a numerical value that is interpreted as described above.
