Table 6.184 — DRM_Predefined_Function

Property

Description

Class
  • <DRM Predefined Function>

Superclass

Subclass
  • None.

Definition

An instance of this DRM class is a <DRM Function> for which the function being used to determine the value of the expression is one of those enumerated by Predefined_Function.

For a <DRM Predefined Function> instance, the function field specifies the function to be used to determine the value of the expression when it is evaluated.

Clarifications

1 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.
