NAME

       DBIx::Recordset::FileSeq - Sequence generator in Filesystem

SYNOPSIS

        use DBIx::Recordset::FileSeq ;

        $self = DBIx::Recordset::FileSeq (undef, '/tmp/seq', $min, $max) ;

        $val1 = $self -> NextVal ('foo') ;
        $val2 = $self -> NextVal ('foo') ;
        $val3 = $self -> NextVal ('bar') ;

DESCRIPTION

       DBIx::Recordset::FileSeq generates unique numbers. State is kept in the filesystem. With
       the new constructor you specify the directory where the state is kept. (First parameter is
       a dummy values, that will receive the database handle from DBIx::Recordset, but you don't
       need it when you use it without DBIx::Recordset). Optionaly you can give a min and a max
       values, which will be used for new sequences.

       With NextVal you can get the next value for the sequence of the given name.

       The state if kept by haveing a file with the name

       seq.<seqencename>.<max>.<count>

       Each time the sequnce value increments the file is renamed. If the <max> if a numeric
       value the new value is checked against <max> and NextVal dies if the sequnce value
       increment above max.
