示例1: WebHistoryInflate
static jint WebHistoryInflate(JNIEnv* env, jobject obj, jint frame, jbyteArray data)
{
ALOG_ASSERT(frame, "Inflate needs a valid frame pointer!");
ALOG_ASSERT(data, "Inflate needs a valid data pointer!");
// Get the actual bytes and the length from the java array.
const jbyte* bytes = env->GetByteArrayElements(data, NULL);
jsize size = env->GetArrayLength(data);
// Inflate the history tree into one HistoryItem or null if the inflation
// failed.
RefPtr<WebCore::HistoryItem> newItem = WebCore::HistoryItem::create();
WebHistoryItem* bridge = new WebHistoryItem(newItem.get());
newItem->setBridge(bridge);
// Inflate the item recursively. If it fails, that is ok. We'll have an
// incomplete HistoryItem but that is better than crashing due to a null
// item.
// We have a 2nd local variable since read_item_recursive may change the
// ptr's value. We can't pass &bytes since we have to send bytes to
// ReleaseByteArrayElements unchanged.
const char* ptr = reinterpret_cast<const char*>(bytes);
readItemRecursive(newItem.get(), &ptr, (int)size);
env->ReleaseByteArrayElements(data, const_cast<jbyte*>(bytes), JNI_ABORT);
bridge->setActive();
// Add the new item to the back/forward list.
WebCore::Frame* pFrame = (WebCore::Frame*)frame;
pFrame->page()->backForwardList()->addItem(newItem);
// Update the item.
bridge->updateHistoryItem(newItem.get());
// Ref here because Java expects to adopt the reference, and as such will not
// call ref on it. However, setBridge has also adopted the reference
// TODO: This is confusing as hell, clean up ownership and have setBridge
// take a RefPtr instead of a raw ptr and calling adoptRef on it
bridge->ref();
return reinterpret_cast<jint>(bridge);
