示例1: visitChildren
void WeakMapData::visitChildren(JSCell* cell, SlotVisitor& visitor)
{
Base::visitChildren(cell, visitor);
WeakMapData* thisObj = jsCast<WeakMapData*>(cell);
visitor.addUnconditionalFinalizer(&thisObj->m_deadKeyCleaner);
visitor.addWeakReferenceHarvester(&thisObj->m_deadKeyCleaner);
// Rough approximation of the external storage needed for the hashtable.
// This isn't exact, but it is close enough, and proportional to the actual
// external mermory usage.
visitor.reportExtraMemoryUsage(thisObj->m_map.capacity() * (sizeof(JSObject*) + sizeof(WriteBarrier<Unknown>)));
