Tie::Array::Sorted::Lazy - phpMan

NAME
    Tie::Array::Sorted::Lazy - An array which is kept sorted

SYNOPSIS
            use Tie::Array::Sorted::Lazy;

            tie @a, "Tie::Array::Sorted::Lazy", sub { $_[0] <=> $_[1] };

            push @a, 10, 4, 7, 3, 4;
            print "@a"; # "3 4 4 7 10"

DESCRIPTION
    This is a version Tie::Array::Sorted optimised for arrays which are
    stored to more often than fetching. In this case the array is resorted
    on retrieval, rather than insertion. (It only re-sorts if data has been
    modified since the last sort).

            tie @a, "Tie::Array::Sorted::Lazy", sub { -s $_[0] <=> -s $_[1] };
