HistHandler_TH3() [1/2]

CP::HistHandler_TH3::HistHandler_TH3

(

TH1 *

hist

)

The HistHandler TH3 handles 3D histograms, since TH3 inhertis from TH1,a TH1* object is parsed avoiding the dynamic cast.

Via the GetDimension() method of the TH1 the class ensures that the histogram has actual dimension 3. No specific TH3 method is required in all use-caes of the class.
