RooAbsString is the common abstract base class for objects that represent a string value.
Definition: RooAbsString.h:25
Bool_t operator==(const char *) const
Equality operator comparing with a TString.
TString traceEval() const
Calculate current value of object, with error tracing wrapper.
virtual void setTreeBranchStatus(TTree &t, Bool_t active)
(De)Activate associated tree branch
virtual void attachToTree(TTree &t, Int_t bufSize=32000)
Attach object to a branch of given TTree.
virtual Bool_t isIdentical(const RooAbsArg &other, Bool_t assumeSameType=kFALSE)
virtual ~RooAbsString()
virtual Bool_t traceEvalHook(const char *value) const
Hook function for trace evaluation.
virtual void writeToStream(std::ostream &os, Bool_t compact) const
