IUnknownTypeOnStream is an exception class thrown by the streaming framework.
This exception signals an object with an unknown type was encountered while reading from an IDataStream. One situation that can cause this error is that the DLL with the class implementation for the type is not loaded in the process that is reading from the stream.
Constructors & DestructorUse these functions to construct, copy and destroy instances of IUnknownTypeOnStream.
![]() |
public:
virtual ~IUnknownTypeOnStream()
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
![]() |
Used to construct objects of this class.
public:
IUnknownTypeOnStream(const IUnknownTypeOnStream& other)
The copy constructor is provided so that the compiler can make copies of the object during the throwing of an exception.
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
public:
IUnknownTypeOnStream( const char* text = 0, long errorID = 0, Severity severity = recoverable )
This constructor is used by the streaming implementation when the error condition is detected. It would not normally be used by application code.
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
Exception TypeUse these members to determine the name (type) of the exception. This is used for logging out an exception object's error information.
![]() |
public:
virtual const char* name() const
Gets the name of the class.
