Key for storing Grasshopper 1 instance IDs in the custom values of an object.

Key for a Grasshopper 1 instance id naming this parameter as the source of that object's outgoing wires.

Gets a string describing the build date of Grasshopper 1.

Gets the type which describes the IGH_Component interface as defined in Grasshopper 1.

Gets the type which describes the IGH_DocumentObject interface as defined in Grasshopper 1.

Gets the Grasshopper 1.0 interop object, i.e. an instance of GrasshopperPlugin.GrasshopperInterop as exposed via the GetInteropObject() method on the Grasshopper 1.0 plugin object.
