REQUIRES

perl5.005, Exporter, Dicop, Dicop::Event, Dicop::Data, Math::BigInt, Math::String, Digest::MD5

EXPORTS

Exports nothing on default.

DESCRIPTION

This is a subclass of Dicop::Data::Chunk and used to store in the checklist of a job. These chunks are mostly like all other chunks, but are marked as belonging to the checklist by their classname.

In addition, they also have some additional methods that are only necessary for chunks in the checklist, namely shrink().

METHODS

In addition to the normal methods of Dicop::Data::Chunk, the following methods are overwritten or new:

shrink

        $self->shrink($result,$factor,$fixed);

Takes the chunk and a result between start and end and shrinks the chunk around the result to 1/$factor of the original size. Also takes care to round the new borders up and down, respectively, so that the new chunk size is always smaller or equal to the old one. Also takes care of "fixed chars" at the two new borders.

Example for $factor == 10:

        original start  <--|
                           | 9/20
        new start       <--|            <---|
                           | 1/20           | new size:
        result          <--|                | 2/20 == 1/10
                           | 1/20           |
        new end         <--|            <---|
                           | 9/20
        original end    <--|

Return error string on error, otherwise $self.
