#109 Probably wrong parameter is passes to getASMSource function
Author: developer honfika
Date created:
Type: bug
Visibility: Everybody
Assigned to:
Labels: FFDec source
State: closed Help

In the following line of SWFInputStream.java (currently line 598) System.err.println("getConstantPool ip " + ip + ", addr " + Helper.formatAddress(((Action) ins).getAddress()) + ": " + ((Action) ins).getASMSource(new ArrayList<GraphSourceItem>(), new ArrayList<Long>(), Helper.toList(cpool), version, false) + add + " stack:" + Helper.stackToString(stack, Helper.toList(cpool))); the 3rd parameter of getASMSource probably should be cpool.constants instead of Helper.toList, because getASMSource waits a List<String> and in some other places cpool.constants is passed to the function.

I found this problem, when added the generic type parameters. I created a changeset which adds the type parameters. Please could you merge it to your branch. (If you are not against it) This changeset contains the modifications of issue #106, too. You can find the changeset here: https://code.google.com/r/honfika-ffdectest/source/detail?r=7f889c18fee4112464853cda66f80c a209785467

What is the difference between List localData and List<Object> localData. I thought it is the same thing, isn't it?
developer
For example you have the following methods: public static void m1(List<String> a) { String s = a.get(0); } public static void m2(List<Object> a) { Object o = a.get(0); } public static void m3(List a) { a.add(new Object()); } public static void main(String[] args) { List list = new ArrayList(); list.add(new Object()); List<Object> objList = new ArrayList<Object>(); objList.add(new Object()); List<String> stringList = new ArrayList<String>(); stringList.add(""); // m1(objList); compile error m2(objList); m3(objList); m1(stringList); // m2(stringList); compile error m3(stringList); m1(list); m2(list); m3(list); } 1st problem: You can call m1 with a "list" parameter, which accepts "List<String>". You will get runtime exceptions. 2nd problem: You can call m3 with stringList parameter, and it will add an Object to the List<String> So if you specify it to List<Object>, you wont be able to call it with List<String>, so it is safer.

If you need to call a function with List<Object> ad List<String> too, then you can use: "? extends Object" public static void m4(List<? extends Object> a) { // a.add(new Object()); compile error } In this case you won't be able to add a new item to the list inside the method.
