Member Function Documentation

string Custom600Headers ( ) [virtual]

Custom headers to be sent to the fetch process.

Returns:
a string containing RFC822-style headers that are to be inserted into the 600 URI Acquire message sent to the fetch subprocess. The headers are inserted after a newline-less line, so they should (if nonempty) have a leading newline and no trailing newline.

Reimplemented from pkgAcquire::Item.

References LastGoodSig.

virtual string DescURI ( ) [inline, virtual]

A "descriptive" URI-like string.

Returns:
a URI that should be used to describe what is being fetched.

Implements pkgAcquire::Item.

References RealURI.

virtual void Done ( string  Message,
unsigned long  Size,
string  Hash,
pkgAcquire::MethodConfig Cnf 
) [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.

Parameters:
MessageData from the acquire method. Use LookupTag() to parse it.
SizeThe size of the object that was fetched.
HashThe HashSum of the object that was fetched.
CnfThe method via which the object was fetched.

pkgAcqMethod

Reimplemented from pkgAcquire::Item.

virtual void Failed ( string  Message,
pkgAcquire::MethodConfig Cnf 
) [virtual]

Invoked by the acquire worker when the object couldn't be fetched.

This is a branch of the continuation of the fetch process.

Parameters:
MessageAn RFC822-formatted message from the acquire method describing what went wrong. Use LookupTag() to parse it.
CnfThe method via which the worker tried to fetch this object.
See also:
pkgAcqMethod

Reimplemented from pkgAcquire::Item.
