Class Description

 RooRealMPFE is the multi-processor front-end for parallel calculation
 of RooAbsReal objects. Each RooRealMPFE forks a process that calculates
 the value of the proxies RooAbsReal object. The (re)calculation of
 the proxied object is started asynchronously with the calculate() option.
 A subsequent call to getVal() will return the calculated value when available
 If the calculation is still in progress when getVal() is called it blocks
 the calling process until the calculation is done.
 The forked calculation process is terminated when the front-end object
 is deleted

RooRealMPFE(const char *name, const char *title, RooAbsReal& arg, Bool_t calcInline) : RooAbsReal(name,title), _state(Initialize), _arg("arg","arg",this,arg), _vars("vars","vars",this), _verboseClient(kFALSE), _verboseServer(kFALSE), _inlineMode(calcInline)

RooRealMPFE(const RooRealMPFE& other, const char* name) : RooAbsReal(other, name), _state(other._state), _arg("arg",this,other._arg), _vars("vars",this,other._vars), _verboseClient(other._verboseClient), _verboseServer(other._verboseServer), _inlineMode(other._inlineMode), _forceCalc(other._forceCalc)
