IDynamicConceptProviderConcept::GetConcept method (dbgmodel.h)
The GetConcept method on a dynamic concept provider is effectively an override of the GetConcept method on IModelObject. The dynamic concept provider must return an interface for the queried concept if it exists as well as any metadata associated with that concept. If the concept does not exist on the provider, that must be indicated via a false value being returned in the hasConcept argument and a successful return. Failure of this method is a failure to fetch the concept and will explicitly halt the search for the concept. Returning false for hasConcept and a successful code will continue the search for the concept through the parent model tree.
Syntax
HRESULT GetConcept(
IModelObject *contextObject,
REFIID conceptId,
IUnknown **conceptInterface,
IKeyStore **conceptMetadata,
bool *hasConcept
);
Parameters
contextObject
The instance object (this pointer) for which to get a concept.
conceptId
The GUID which identifies the concept being acquired. This GUID uniquely identifies both the concept and the core interface of the concept. It is the interface id (IID) of the primary interface for a defined concept.
conceptInterface
The core interface to the concept as defined by the conceptId argument is returned here.
conceptMetadata
Any metadata which is associated with the concept can optionally be returned here.
hasConcept
An indication of whether the dynamic provider has the concept is returned here. If the provider does not have the concept, the value false should be returned here and the method should succeed.
Return value
This method returns HRESULT which indicates success or failure.
