COMPersistHelper::__construct — Construct a COMPersistHelper object

说明

public COMPersistHelper::__construct(?variant $variant = null)

Constructs a persistence helper object, usually associated with a variant.

参数

variant
A COM object which implements IDispatch. To be able to successfully call any of COMPersistHelper's methods, the object has to implement IPersistFile, IPersistStream and/or IPersistStreamInit. Passing null as variant is only useful if the object is to be loaded from a stream by calling COMPersistHelper::LoadFromStream().
