Mapping of Type
Since there is no counterpart to the UNO type among the Automation types, it is mapped to an object. The object implements
IDispatch and a private tagging interface that is known to the bridge. Therefore, whenever an object is passed in a call to a UNO object the bridge can determine whether it represents a type. To obtain a type one calls
Bridge_CreateType on the service manager object and provides the name of the type. For example:
'Visual Basic Dim objType Set objType = objServiceManager.Bridge_CreateType(“com.sun.star.uno.XInterface”)
In case the provided argument does not represent a valid type, the call produces an error.
If a UNO method returns a type, either as return value or out - parameter, then it is automatically converted to an object.
//UNOIDL type foo([out] type t)
'Visual Basic Dim objParam As Object Dim objReturn As Object Set objReturn = object.foo(objParam)
