# 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] };
