The PendingOperation class is a base class for pending asynchronous operations.
This class represents an incomplete asynchronous operation, such as a D-Bus method call. When the operation has finished, it emits finished(). The slot or slots connected to the finished() signal may obtain additional information from the pending operation.
In simple cases, like a D-Bus method with no 'out' arguments or for which all 'out' arguments are to be ignored (so the possible results are success with no extra information, or failure with an error code), the trivial subclass PendingVoid can be used.
For pending operations that produce a result, another subclass of PendingOperation can be used, with additional methods that provide that result to the library user.
After finished() is emitted, the PendingOperation is automatically deleted using deleteLater(), so library users must not explicitly delete this object.
The design is loosely based on KDE's KJob.
