I thought that 'validity' defined in 'setClass' should be called in
'new'. Could somebody let me know why 'validity' is not called? How to
make it be called?
> setClass(
+ Class='A',
+ representation=representation(
+ x='numeric'
+ ),
+ validity=function(object){
+ cat("~~~ A: inspector ~~~\n")
+ if(obj...@x<0){
+ stop("[A:validation] obj...@x<0")
+ }
+ return(T)
+ }
+ )
[1] "A"
> setMethod(
+ f='initialize',
+ signature='A',
+ definition=function(.Object,x){
+ cat("~~~ A: initializator ~~~\n")
+ .obj...@x=x
+ return(.Object)
+ }
+ )
[1] "initialize"
> new(Class='A', x=10)
~~~ A: initializator ~~~
An object of class \u201cA\u201d
Slot "x":
[1] 10
