Member Function Documentation

value()

const EitherType value

(

)

const

Return the value as a castable value into the approriate type

For instance,

Value v1(5.0); // v1 is of type double
Value v2(3);   // v2 is of type int
double x1 = v1.value();
double x2 = v2.value();

The first assignment will succeed, while the second one will throw an exception.
