Definition

An instance of one of the concrete subclasses of this abstract 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> - and passing them through the specified function.

Clarifications

1 The value_type of a <DRM Function> instance is the “return type” of that <DRM Function> instance - that is, the value_type of the value produced when the <DRM Function> instance is evaluated for its arguments.

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