// Synopsis: Interface implemented by object exporters.
|
||
|
|
//
|
||
|
|
// This is the interface that needs to be supported by hosts that export
|
||
|
|
// objects. Only one instance of this interface can be exported by the host.
|
||
|
|
//
|
||
|
|
// An object exporter needs to be able to:
|
||
|
|
// 1. return string bindings that can be used to talk to objects it
|
||
|
|
// has exported
|
||
|
|
// 2. receive pings from object importers to keep the objects alive
|
||
|
|
//
|
||
|
|
// Note that changes to this interface can effect IActivation because the
|
||
|
|
// RemoteActivation method of IActivation includes information otherwise
|
||
|
|
// retrieved from ResolveOxid.
|
||
