QUESTION
I'm trying to perform an action over a 4-dimensional array. This array ends up being incredibly big, but is necessary for the data that i'm processing. Now the process itself goes swell, but i want to make it ready for parallel computing. I've got access to a 96-core mainframe and i want to use it.
So far i've read online that the easiest way to get this done is by using mclapply(), the parallelized version of lapply(). I know the basics of how lapply() works, but i can't quite figure out how to apply it in this situation.
I have a 4-dimensional array that's filled with NAs. Each dimension has dimnames. I want to compare the dimnames of dimension 1 with dimension 3 and dimension 2 with dimension 4 (this is done by a custom function that i wrote). If they all match up, a number comes out and i want that number to be entered into xy[i, k, j, l] where the letters i-l represent the indices for one entry.
In the example below i have simplified it into an addition of the nchar() values for the dimnames.

a <- nchar(Var1) + nchar(Var3)
b <- nchar(Var2) + nchar(Var4)
if(!is.null(a) & !is.null(b)) return(a + b)
else return(NA)
}
xy[] <- do.call(parallel::mcmapply,
c(list(FUN = fun_on_names, mc.cores = 96),
expand.grid(dimnames(xy), stringsAsFactors = FALSE)))

QUESTION
Sorry for the title, i have no idea to get better title.
I create a simple servlet and implements CDI interceptor.
This is my servlet
...ANSWER
Answered 2017-Nov-03 at 00:51When you create an interceptor, it's invoked either before or after your method is called. With the way you have written yours, it is invoked before your method is called. InvocationContext.proceed
will effectively call your method (and other interceptors if others are wired in).
