...(I'll use Java for the examples): Example 1: class Foo { static String st = "Hello"; void f1() { f2(st); } void f2(String s) { st = null; // Destroy static root // Now allocate something, which might trigger // a garbage collection. StringBuffer sb = new StringBuffer(); // Is 's' still live? It's not stored in any // alloca, or in any global variable. It only // exists as a function parameter, which cannot // be declared as a root via llvm.gcroot. sb.append(s); } } Example 2: class Foo...

...esult it builds up strings to visualize the result. The external function is really fast, also for huge input data. But the building of the strings takes much to long for huge input sizes. So I'm wondering if the concatenating could be the problem, like using String in Java instead of StringBuffer. Is there something like StringBuffers in R also? Thanks, T. Steijger

So I've managed to get my stack crawler working and passing its unit tests - this is the one I've been working on as an alternative to shadow-stack: it uses only static constant data structures (no global variables or thread-local data), which means that it's fully compatible with a multi-threaded environment. One question that has arisen, however, is what to do about function

Hi everyone, Has anyone written a parser in Java for either the ASCII or binary format produced by save()? I need to parse a single large 2D array that is structured like this: list( "32609_1" = c(-9549.39231289146, -9574.07159324482, ... ), "32610_2" = c(-6369.12526971635, -6403.99620977124, ... ), "32618_2" = c(-2138.29095689061, -2057.9229403233, ... ),

I am calling R from within Java. But I don't think that I can get any plots written to file from R - inside Java. This snippet of code(from a larger piece of code) compiles in Java, but doesn't do anything! functions.append("trial<-c(1,3,4,5)\n"); functions.append("dawpdf<-function(filename){\n");
