ULong_t Hash() const
Return hash value for this object.
The TEnv class reads config files, by default named .rootrc.

Change the value of a resource.

virtual void Print(Option_t *option="") const
This method must be overridden when a class wants to print itself.
UInt_t Hash(ECaseCompare cmp=kExact) const
Return hash value.
