FakeIDispatch

Overview

The FakeIDispatch class is an empty class that implements the IDispatch interface. Since all cross-platform interfaces inherit from IDispatch, every object that implements this interface must also implement the IDispatch methods. In most cases, these methods are not needed and the FakeIDispatch class can be used as base class for objects that implement cross-platform interfaces.

In the Hydra framework, this class is used as a base class for cross-platform wrappers.

GetTypeInfo

Retrieves the type information for an object, which can then be used to get the type information for an interface. Empty.

GetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1). Empty

 

// Island-Ubuntu
method GetTypeInfoCount(pctinfo: ^UInt32): HRESULT
// Island-Windows
method GetTypeInfoCount(pctinfo: ^UINT): HRESULT

// Island-Windows
Function GetTypeInfoCount(pctinfo As Ptr(Of UINT)) As HRESULT

Parameters:

  • pctinfo: The number of type information interfaces provided by the object. If the object provides type information, this number is 1; otherwise the number is 0.
