Hierarchy of classes which Xapian can throw as exceptions.
Decide if a Xapian::Error exception should be ignored.
bool already_handled
True if this error has already been passed to an ErrorHandler.
Definition: error.h:86
void operator()(Xapian::Error &error)
Handle a Xapian::Error object.
Definition: errorhandler.cc:29
virtual ~ErrorHandler()
We require a virtual destructor because we have virtual methods.
Definition: errorhandler.cc:26
All exceptions thrown by Xapian are subclasses of Xapian::Error.
Definition: error.h:43
virtual bool handle_error(Xapian::Error &error)=0
Perform user-specified error handling.
