Here we're dealing with COM objects implemented in Lua. Typically the
COM server will call a Lua function (like StartAutomation) to
do this task.
There are two different situations, which one demands different
actions:
- Implementing the Application Object
- Here we must use the
LuaCOM method
NewObject
to create a COM object and
bind it to the table of the Lua Application Object. Them this object must
be made available to other applications through ExposeObject
.
- Implementing other objects
- The other objects of the component
are obtained via the Lua Application Object as return values of
functions or as values stored in the fields of the Lua Application
Object (that is, via property access). These object should be
implemented using
ImplInterface
. They can be implemented
in the initialization (and then be stored somewhere) or can be
implemented on-demand (that is, each time a COM object should be
return, a call to ImplInterface
is made).
Notice that the fields of the Lua table used to implement COM
component will only be accessible if they are present in the type
library. If not, they are invisible to COM.
