示例1: PodZero
uint32_t
Table::grow(uint32_t delta, JSContext* cx)
{
// This isn't just an optimization: movingGrowable() assumes that
// onMovingGrowTable does not fire when length == maximum.
if (!delta)
return length_;
uint32_t oldLength = length_;
CheckedInt<uint32_t> newLength = oldLength;
newLength += delta;
if (!newLength.isValid() || newLength.value() > MaxTableLength)
return -1;
if (maximum_ && newLength.value() > maximum_.value())
return -1;
MOZ_ASSERT(movingGrowable());
JSRuntime* rt = cx; // Use JSRuntime's MallocProvider to avoid throwing.
// Note that realloc does not release array_'s pointee (which is returned by
// externalArray()) on failure which is exactly what we need here.
ExternalTableElem* newArray = rt->pod_realloc(externalArray(), length_, newLength.value());
if (!newArray)
return -1;
Unused << array_.release();
array_.reset((uint8_t*)newArray);
// Realloc does not zero the delta for us.
PodZero(newArray + length_, delta);
length_ = newLength.value();
