Subclass

Definition

An instance of this DRM class specifies an expression for which the value is determined by evaluating the arguments of the expression (the ordered <DRM Expression> components of the <DRM Function> instance) and using the results to evaluate the function.

The value_type of a <DRM Function> instance specifies the type of value returned.

Clarifications

1The <DRM Expression> components of a <DRM Function> instance, if any, represent the arguments of the function being represented, so a <DRM Function> instance has <DRM Expression> components if that <DRM Function> instance takes arguments. The <DRM Expression> components are ordered so as to unambiguously specify which <DRM Expression> component is being supplied for each argument of the <DRM Function> instance. The exact interpretation of each argument is defined by the specific function.
