IHostDataModelAccess interface (dbgmodel.h)

When DebugExtensionInitialize is called, it creates a debug client and gets access to the data model. Such access is provided by a bridge interface between the legacy IDebug* interfaces of Debugging Tools for Windows and the data model. This bridge interface is IHostDataModelAccess.

Inheritance

IHostDataModelAccess inherits from IUnknown.

Methods

The IHostDataModelAccess interface has these methods.

IHostDataModelAccess::AddRef The IHostDataModelAccess::AddRef method increments the reference count for an interface on an object.
IHostDataModelAccess::GetDataModel The GetDataModel method is the method on the bridge interface which provides access to both sides of the data model.
IHostDataModelAccess::QueryInterface The IHostDataModelAccess::QueryInterface method retrieves pointers to the supported interfaces on an object.
IHostDataModelAccess::Release The IHostDataModelAccess::Release method decrements the reference count for an interface on an object.

Remarks

An interface suggested on the per-host extensibility mechanism to get from the host extensibility mechanism to the model based one. Extensions which are written to a host-specific API set can query this mechanism to get to the data model and create host-agnostic extensions.

As an example, DbgEng based extensions can query for this interface from any IDebug* (Client/Control/etc...) interface to get to the model and access model APIs. Such extensions are hybrid (they are still specific to a particular host but contain portions that may be factored out later for a general model based extension).

This is the ONLY interface in this set of APIs which is not intended to be host agnostic.
