示例1: setLocal
bool DebugStackFrame::setLocal(int which, Atom& val)
{
bool worked = false;
if (trace->framep() && trace->info())
{
int firstLocal, pastLastLocal;
localBounds(&firstLocal, &pastLastLocal);
int count = pastLastLocal - firstLocal;
if (count > 0 && which < count)
{
MethodInfo* info = trace->info();
if (which == 0 && info->needRestOrArguments())
{
// They are trying to modify the first local, but that is actually the special
// array for "...rest" or for "arguments". That is too complicated to allow
// right now. We're just going to fail the request.
}
else
{
// copy the single arg over
info->unboxLocals(&val, 0, trace->types(), trace->framep(), firstLocal+which, 1);
worked = true;
}
}
}
return worked;
}示例2: locals
/**
* @return a pointer to an object Atom whose members are
* the active locals for this frame.
*/
bool DebugStackFrame::locals(Atom*& ar, int& count)
{
bool worked = true;
if (trace->framep() && trace->info())
{
int firstLocal, pastLastLocal;
localBounds(&firstLocal, &pastLastLocal);
count = pastLastLocal - firstLocal;

if ((count > 0) && debugger)
{
// frame looks like [this][param0...paramN][local0...localN]

MethodInfo* info = trace->info();
info->boxLocals(trace->framep(), firstLocal, trace->types(), ar, 0, count);
// If NEED_REST or NEED_ARGUMENTS is set, and the jit is being used, then the first
// local is actually not an atom at all -- it is an ArrayObject*. So, we need to
// convert it to an atom. (If the interpreter is being used instead of the jit, then
// it is stored as an atom.)
if (info->needRestOrArguments())
{
int atomType = atomKind(ar[0]);

{
ScriptObject* obj = (ScriptObject*)ar[0];
ar[0] = obj->atom();
