double QUESO::ScalarTimesFunc1D1DFunction::value ( double  domainValue ) const

virtual

Returns the value of the (one-dimensional) function at point domainValue, already multiplied by the scalar (given during construction).

This function calls the value() method of the given function and multiplies its return value by the scalar passed to the constructor.
