virtual UInt_t ADF::Signal::GetLast ( ) const

inlinevirtualinherited

Return the real last position used.

When asking for a given value in the array, one may ask for out of range values. To avoid throwing exceptions (even if it could be better), the first value is always return in case of out of range. To check if you get the value you want:

Signal s(10u);

s.Set(1,1u);             // s.GetLast() = 1
Double_t d = s.Get(d,9); // s.GetLast() = 9             
s.Set(-2,11u) = -2.      // s.GetLast() = 9 !! not 11
