示例1:
BytesOTE* __fastcall ObjectMemory::shallowCopy(BytesOTE* ote)
{
ASSERT(ote->isBytes());
// Copying byte objects is simple and fast
VariantByteObject& bytes = *ote->m_location;
BehaviorOTE* classPointer = ote->m_oteClass;
MWORD objectSize = ote->sizeOf();
OTE* copyPointer;
// Allocate an uninitialized object ...
VariantByteObject* pLocation = static_cast<VariantByteObject*>(allocObject(objectSize, copyPointer));
ASSERT((objectSize > MaxSizeOfPoolObject && copyPointer->heapSpace() == OTEFlags::NormalSpace)
|| copyPointer->heapSpace() == OTEFlags::PoolSpace);
ASSERT(copyPointer->getSize() == objectSize);
// This set does not want to copy over the immutability bit - i.e. even if the original was immutable, the
// copy will never be.
copyPointer->setSize(ote->getSize());
copyPointer->m_dwFlags = (copyPointer->m_dwFlags & ~OTEFlags::WeakMask) | (ote->m_dwFlags & OTEFlags::WeakMask);
ASSERT(copyPointer->isBytes());
copyPointer->m_oteClass = classPointer;
classPointer->countUp();
// Copy the entire object over the other one, including any null terminator and object header
memcpy(pLocation, &bytes, objectSize);
return reinterpret_cast<BytesOTE*>(copyPointer);
}示例2: newVirtualObject
// N.B. Like the other instantiate methods in ObjectMemory, this method for instantiating
// objects in virtual space (used for allocating Processes, for example), does not adjust
// the ref. count of the class, because this is often unecessary, and does not adjust the
// sizes to allow for fixed fields - callers must do this
VirtualOTE* ObjectMemory::newVirtualObject(BehaviorOTE* classPointer, MWORD initialSize, MWORD maxSize)
{
#ifdef _DEBUG
{
ASSERT(isBehavior(Oop(classPointer)));
Behavior& behavior = *classPointer->m_location;
ASSERT(behavior.isIndexable());
}
#endif
// Trim the sizes to acceptable bounds
if (initialSize <= dwOopsPerPage)
initialSize = dwOopsPerPage;
else
initialSize = _ROUND2(initialSize, dwOopsPerPage);
if (maxSize < initialSize)
maxSize = initialSize;
else
maxSize = _ROUND2(maxSize, dwOopsPerPage);
// We have to allow for the virtual allocation overhead. The allocation function will add in
// space for this. The maximum size should include this, the initial size should not
initialSize -= sizeof(VirtualObjectHeader)/sizeof(MWORD);
unsigned byteSize = initialSize*sizeof(MWORD);
VariantObject* pLocation = reinterpret_cast<VariantObject*>(AllocateVirtualSpace(maxSize * sizeof(MWORD), byteSize));
if (pLocation)
{
// No need to alter ref. count of process class, as it is sticky
// Fill space with nils for initial values
const Oop nil = Oop(Pointers.Nil);
const unsigned loopEnd = initialSize;
for (unsigned i = 0; i < loopEnd; i++)
pLocation->m_fields[i] = nil;
OTE* ote = ObjectMemory::allocateOop(static_cast<POBJECT>(pLocation));
ote->setSize(byteSize);
ote->m_oteClass = classPointer;
classPointer->countUp();
ote->m_flags = m_spaceOTEBits[OTEFlags::VirtualSpace];
ASSERT(ote->isPointers());
return reinterpret_cast<VirtualOTE*>(ote);
}
return nullptr;
