CoreInterfaces/plugin.h File Reference

---

Detailed Description

plugin.h defines the DLL's exported (and imported) functions that make it a loadable Digital Spaces component.

It also includes the header files to define the required data types. The exported functions are:

• GetComponentInfo
• PerformStartupStep
• PerformLastStartupStep
• RenderFrame
• StopPlugin These functions are documented below.

The imported function is:

• GetObjectsWithInterface This function is implemented in the Digital Spaces Core and allows components to request pointers to all objects that implement the specified interface.

The additionally included header files are ReplaceObjBase.h and ContainerInterfaces.h ReplaceObjBase.h defines the DUID data type (128 bit value, same as COM GUID, but not dependant on the GUID implementation). It also defines some operators for working with the DUID values, specifically operator== and operator< . The DInterface type is also defined here, as is the DIObjectBase interface, from which every Digital Spaces object derives. Also the CLSIDFromString function is defined.
