Internalising a Swizzle from a stream has assignment semantics.

The process of internalisation assumes that the current position within the stream contains the external representation of a stream ID. The stream which corresponds to this ID contains the external representation of some object.

The result is a Swizzle which represents the object by stream ID.

The following code fragments illustrate the process.

iB is a CClassB type component of a class CClassABC, and is represented by a Swizzle. The data member is defined as:

class CCClassABC : public CBase - { - ... - TSwizzle<CClassB> iB; - ... - } -

The example assumes that the stream ID of the swizzled object has been externalised as in Externalizing a Swizzle.

CClassB's RestoreL() and InternalizeL() functions are implemented as:

void CClassABC::RestoreL() - { - RStoreReadStream stream; - stream.OpenLC(iStore,iId); - InternalizeL(stream); - CleanupStack::PopAndDestroy(); - } void CClassABC::InternalizeL(RReadStream& aStream) - { - ... - aStream >> iB; // internalises Swizzle from stream - ... - }

Here, iId is the stream ID containing CClassABC data.
