Hi all,
I have same problem with bcel api, so I try to answere in this list.
1) How can I get the class variable name about the method that is invoked?
Explain: I have this example code.
String s = "hello";
String g = "world";
int i = s.lenght();
How can I retrieve the name of the variable where i call the method
lenght()? I want the variable name "s"!
Because if I lunch the command "javap -verbose ClassName" I obtain the
bytecode for the class ClassName and I can't get directly the name of
the class where the method is called. For the example code I can get
only that lenght() is a method of the class String but not the name of
the variable "s".
2) If I didn't compile the file class with "javac -g" I can't have the
LocalVariableTable, ok? But can I know if a variable is declarated
internally in the method or is a global variable of the class?
HashSet<String> argsVar = new HashSet<String>();
String[] args = mg.getArgumentNames(); //mg is a MethodGen variable
int k = 0;
int nArgs = args.length;
while(k < nArgs){
argsVar.add(args[k]);
k++;
}
3) The bytecode instructions aload_0 refears always at: args if the
method is the main; this otherwise?
Sorry for my bad English.
Thanks for the attention.
Marco.
