Names of Slots Inherited From a Super Class

Description

For a class (or class definition, see getClass and the description of class classRepresentation), give the names which are inherited from “above”, i.e., super classes, rather than by this class' definition itself.

Usage

inheritedSlotNames(Class, where = topenv(parent.frame()))

Arguments

`Class`	character string or `classRepresentation`, i.e., resulting from `getClass`.
`where`	environment, to be passed further to `isClass` and `getClass`.

Value

character vector of slot names, or NULL.

Examples

.srch <- search()
library(stats4)
inheritedSlotNames("mle")

if(require("Matrix", quietly = TRUE)) withAutoprint({
  inheritedSlotNames("Matrix")       # NULL
  ## whereas
  inheritedSlotNames("sparseMatrix") # --> Dim & Dimnames
  ##  i.e. inherited from "Matrix" class
  cl <- getClass("dgCMatrix")        # six slots, etc
  inheritedSlotNames(cl) # *all* six slots are inherited
})
## Not run: 
## detach package we've attached above:
for(n in rev(which(is.na(match(search(), .srch)))))
   try( detach(pos = n) )

## End(Not run)
