Members

Public Methods

Name	Description
IPersistStreamInitImpl::GetClassID	Retrieves the object's CLSID.
IPersistStreamInitImpl::GetSizeMax	Retrieves the size of the stream needed to save the object's data. The ATL implementation returns E_NOTIMPL.
IPersistStreamInitImpl::InitNew	Initializes a newly created object.
IPersistStreamInitImpl::IsDirty	Checks whether the object's data has changed since it was last saved.
IPersistStreamInitImpl::Load	Loads the object's properties from the specified stream.
IPersistStreamInitImpl::Save	Saves the object's properties to the specified stream.

Remarks

The IPersistStreamInit interface allows a client to request that your object loads and saves its persistent data to a single stream. Class IPersistStreamInitImpl provides a default implementation of this interface and implements IUnknown by sending information to the dump device in debug builds.
