Function Documentation

IlvRead()

template<class OBJECT >

IlvRefCountPtr<IlvOwnership<OBJECT> > IlvRead	(	IlvInputFile &	is,
		IlvReferenceStreamer &	streamer
	)

This helper function is used to load an object that may be shared by several adapters.

The type of the object, OBJECT, is given as the template parameter of the function.

The object is stored into an IlvOwnership object that is encapsulated into an IlvRefCountPtr.

Parameters

is	A reference to an IlvInputFile from where to load the object.
streamer	A reference to an IlvReferenceStreamer that will manage the sharing in order that all the adapters that share this object correctly loading of the sharing of the object.

Returns

An IlvRefCountPtr<IlvOwnership<OBJECT> > that contains the object that was loaded from the stream.

IlvWrite()

template<class OBJECT >

void IlvWrite	(	IlvOwnership< OBJECT > &	ownership,
		IlvOutputFile &	os,
		IlvReferenceStreamer &	streamer
	)

This helper function is used to save an object stored into an IlvOwnership<OBJECT> object.

The type of the object, OBJECT, is given as the template parameter of the function.

Parameters

ownership	A reference to an IlvOwnership<OBJECT> instance that contains the object to be saved.
os	A reference to an IlvOutputFile where to save the object.
streamer	A reference to an IlvReferenceStreamer that will manage the sharing in order that the object is actually saved once only by the first adapter. When the object is shared by several adapters, only a reference is saved for all but the first one.
