IModelPropertyAccessor interface (dbgmodel.h)
The data model representation of a property accessor (get/set).
Inheritance
IModelPropertyAccessor inherits from IUnknown.
Methods
The IModelPropertyAccessor interface has these methods.
| IModelPropertyAccessor::AddRef The IModelPropertyAccessor::AddRef method increments the reference count for an interface on an object. |
| IModelPropertyAccessor::GetValue The GetValue method is the getter for the property accessor. It is called whenever a client wishes to fetch the underlying value of the property. |
| IModelPropertyAccessor::QueryInterface The IModelPropertyAccessor::QueryInterface method retrieves pointers to the supported interfaces on an object. |
| IModelPropertyAccessor::Release The IModelPropertyAccessor::Release method decrements the reference count for an interface on an object. |
| IModelPropertyAccessor::SetValue The SetValue method is the setter for the property accessor. It is called whenever a client wishes to assign a value to the underlying property. |
Remarks
A property accessor in the data model is an implementation of the IModelPropertyAccessor interface which is boxed into an IModelObject. The model object will return a kind of ObjectPropertyAccessor when queried and the intrinsic value is a VT_UNKNOWN which is guaranteed to be queryable for IModelPropertyAccessor. In process, it is guaranteed to be statically castable to IModelPropertyAccessor.
A property accessor is an indirect way to get a method call for getting and setting a key value in the data model. If a given key's value is a property accessor, the GetKeyValue and SetKeyValue methods will automatically notice this and call the property accessor's underlying GetValue or SetValue methods as appropriate.
