makeClassRepresentation: Create a Class Definition

Description

Constructs an object of class classRepresentation to describe a particular class. Mostly a utility function, but you can call it to create a class definition without assigning it, as setClass would do.

Usage

makeClassRepresentation(name, slots=list(), superClasses=character(), prototype=NULL, package, validity, access, version, sealed, virtual=NA, where)

Arguments

name

character string name for the class

slots

named list of slot classes as would be supplied to setClass, but without the unnamed arguments for superClasses if any.

superClasses

what classes does this class extend

prototype

an object providing the default data for the class, e.g., the result of a call to prototype.

package

The character string name for the package in which the class will be stored; see getPackageName.

validity

Optional validity method. See validObject, and the discussion of validity methods in the reference.

access

Access information. Not currently used.

version

Optional version key for version control. Currently generated, but not used.

sealed

Is the class sealed? See setClass.

virtual

Is this known to be a virtual class?

where

The environment from which to look for class definitions needed (e.g., for slots or superclasses). See the discussion of this argument under GenericFunctions.
