NAME

       Dpkg::Interface::Storable - common methods related to object serialization

DESCRIPTION

       Dpkg::Interface::Storable is only meant to be used as parent class for other objects. It provides common
       methods that are all implemented on top of two basic methods parse() and output().

BASE METHODS

       Those methods must be provided by the object that wish to inherit from Dpkg::Interface::Storable so that
       the methods provided can work.

       $obj->parse($fh, $desc)
           This methods initialize the object with the data stored in the filehandle. $desc is optional and is a
           textual description of the filehandle used in error messages.

       $string = $obj->output($fh)
           This method returns a string representation of the object in $string and it writes the same string to
           $fh (if it's defined).

PROVIDED METHODS

       $obj->load($filename)
           Initialize the object with the data stored in the file. The file can be compressed, it will be
           uncompressed on the fly by using a Dpkg::Compression::FileHandle object. If $filename is "-", then
           the standard input is read (no compression is allowed in that case).

       $obj->save($filename)
           Store the object in the file. If the filename ends with a known compression extension, it will be
           compressed on the fly by using a Dpkg::Compression::FileHandle object. If $filename is "-", then the
           standard output is used (data are written uncompressed in that case).

       "$obj"
           Return a string representation of the object.
