BindProperty function (dbgmodel.h)
A binder which converts two instance methods on a class to a read/write property accessor. The class must be IUnknown derived. The returned binder will hold reference on the class object.
Usage: BindProperty(this, &MyClass::GetMyProperty, &MyClass::SetMyProperty)
Syntax
Microsoft::WRL::ComPtr<IModelPropertyAccessor> BindProperty(
T *classObject,
HRESULT(T::* )(PCWSTR key,IModelObject *contextObject,IModelObject **value) getMethod,
HRESULT(T::* )(PCWSTR key,IModelObject *contextObject,IModelObject **value) setMethod
);
Parameters
classObject
The instance of a given class to which the newly created property accessor will be bound.
getMethod
A pointer-to-member function pointer of signature (PCWSTR, IModelObject *, IModelObject**) which will act as the getter for the newly created property accessor.
setMethod
A pointer-to-member function of signature (PCWSTR, IModelObject *, IModelObject *) which will act as the setter for the newly created property accessor.
Return value
This function returns Microsoft::WRL::ComPtr<IModelPropertyAccessor>.
Remarks
This sample code shows usage of the BindProperty function.
Note
The code sample uses the recommended DbgModelClientEx.h library header available from GitHub. For more information, see Using the DbgModelClientEx Library.
To see how the DbgModelClientEx library are used, for example, specifying the Debugger::DataModel namespaces, review the Data Model HelloWorld C++ sample: https://github.com/microsoft/WinDbg-Samples/tree/master/DataModelHelloWorld/Cpp
// Define a native type that we wish to project into the data model
struct MyNativeType
{
std::wstring Name;
int Id;
int WriteableValue;
};
// Declare a type factory for the type
class MyNativeTypeFactory : public TypedInstanceModel<MyNativeType>
{
public:
MyNativeTypeFactory()
{
BindReadOnlyProperty(L"Name", &MyNativeType::Name);
BindReadOnlyProperty(L"Id", &MyNativeType::Id);
BindProperty(L"WriteableValue", &MyNativeType::WriteableValue);
}
};
// Create the type factory and make an instance
MyNativeTypeFactory factory;
Object instance = factory.CreateInstance(MyNativeType { L"Foo", 42, 37 });
// There are "Name/Id" read-only properties on instance and a "WriteableValue" property.
