double QUESO::FuncPlusFunc1D1DFunction::value ( double  domainValue ) const

virtual

Returns the value of the addition of function func1 and func2 evaluated at the point domainValue, i.e. returnValue = func1(domainValue)+func2(domainValue) .

This function calls the value() method of the both functions and adds their return value with one another.
