Dpkg::Interface::Storable - common methods related to object serialization
Dpkg::Interface::Storable is only meant to be used as parent
class for other classes. It provides common methods that are
all implemented on top of two basic methods parse() and output().
Those methods must be provided by the class 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).
- $obj->load($filename, %opts)
-
Initialize the object with the data stored in the file. The file can be
compressed, it will be decompressed on the fly by using a
Dpkg::Compression::FileHandle object. If $opts{compression} is false the
decompression support will be disabled. If $filename is ``-'', then the
standard input is read (no compression is allowed in that case).
- $obj->save($filename, %opts)
-
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 $opts{compression} is false the
compression support will be disabled. If $filename is ``-'', then the
standard output is used (data are written uncompressed in that case).
- "$obj"
-
Return a string representation of the object.
New options: The $obj->load() and $obj->save() methods support a new
compression option.
Mark the module as public.
