class net_instaweb::MemberFunction3< C, T1, T2, T3 >
Captures a delayed call to a 3-arg member function as a closure.
template<class C, typename T1, typename T2, typename T3>
Informs a the Function that it is being shut down. If this is called, Run() should not be called. This should never be called while a function is running. See also set_quit_requested(), which can be called during Run(), so that Run() implementations can check quit_requested() at their convenience to stop the operation in progress.
Reimplemented from net_instaweb::Function.
template<class C, typename T1, typename T2, typename T3>
Callers must override this to define the action to take when a closure is run. If this is called, Cancel() should not be called. This is a convention that's expected of callers of Function objects, but is not enforced by the Function implementation.
Implements net_instaweb::Function.
