A "descriptive" URI-like string.

virtual |
Invoked by the acquire worker when the object was fetched successfully.
Note that the object might not have been written to DestFile; check for the presence of an Alt-Filename entry in Message to find the file to which it was really written.
Done is often used to switch from one stage of the processing to the next (e.g. fetching, unpacking, copying). It is one branch of the continuation of the fetch process.
Message | Data from the acquire method. Use LookupTag() to parse it. |
Size | The size of the object that was fetched. |
Hash | The HashSum of the object that was fetched. |
Cnf | The method via which the object was fetched. |
Reimplemented from pkgAcquire::Item.

virtual |
Invoked by the acquire worker when the object couldn't be fetched.
This is a branch of the continuation of the fetch process.
Message | An RFC822-formatted message from the acquire method describing what went wrong. Use LookupTag() to parse it. |
Cnf | The method via which the worker tried to fetch this object. |
