IMoniker::Inverse
Returns a moniker that, when composed to the right of this moniker or one of
similar structure, will destroy it (that is, will compose to nothing).
HRESULT Inverse(
IMoniker **ppmk
 //Receives the inverse of the moniker

);


Parameter
ppmk
[out] Receives a pointer to the inverse moniker. If an error occurs, the
implementation sets
*ppmk to NULL. If *
ppmk is nonNULL, the implementation must call
IUnknown::AddRef on the parameter; it is the caller's responsibility to call
IUnknown::Release.
Return Values
S_OK
The inverse moniker has been returned successfully.
MK_E_NOINVERSE
Indicates that the moniker class does not have an inverse.
E_OUTOFMEMORY
Indicates insufficient memory.
Comments
The inverse of a moniker is analogous to the ".." directory in MSDOS file
systems; the ".." directory acts as the inverse to any other directory name,
because appending ".." to a directory name results in an empty path. In the same
way, the inverse of a moniker typically is also the inverse of all monikers in the
same class. However, it is not necessarily the inverse of a moniker of a
different class.
The inverse of a composite moniker is a composite consisting of the inverses
of the components of the original moniker, arranged in reverse order. For
example, if the inverse of A is Inv( A ) and the composite of A, B, and C is Comp( A,
B, C ), then
Inv( Comp( A, B, C ) )
is equal to
Comp( Inv( C ), Inv( B ), Inv( A ) ).
Not all monikers have inverses. Most monikers that are themselves inverses do
not have inverses; for example, antimonikers do not have inverses. Monikers
that have no inverse cannot have relative monikers formed from inside the objects
they identify to other objects outside.
Notes to Callers
If you're a moniker client, you typically do not know the class of the moniker
you're using. If you need to get the inverse of a moniker, you should always
call
IMoniker::Inverse rather than the
CreateAntiMoniker API function, because you cannot be certain that the moniker you're using
considers an antimoniker to be its inverse.
The
IMoniker::Inverse method is also called by the implementation of the
IMoniker::RelativePathTo method, to assist in constructing a relative moniker.
Notes to Implementors
If your monikers have no internal structure, your implementation of
IMoniker::Inverse can return an antimoniker using the
CreateAntiMoniker API function. Whatever you return from
IMoniker::Inverse is what you must check for in your implementation of
IMoniker::ComposeWith.
