 Destructor



char * GetPointerName()


 Provide a pointer name containing uid.



void SetRadLen(Double_t radlen, Double_t intlen)

Bool_t IsEq(const TGeoMaterial *other)


 return true if the other material has the same physical properties



void SavePrimitive(ostream &out, Option_t * /*option*/ /*= ""*/)


 Save a primitive as a C++ statement(s) on output stream "out".



Int_t GetDefaultColor()


 Get some default color related to this material.



TGeoElement * GetElement(Int_t)


 Get a pointer to the element this material is made of.



Int_t GetIndex()


 Retreive material index in the list of materials



Double_t ScreenFactor(Double_t z)


 static function
  Compute screening factor for pair production and Bremstrahlung
  REFERENCE : EGS MANUAL SLAC 210 - UC32 - JUNE 78
                        FORMULA 2.7.22
