The MFn::Type enumeration is used throughout
the API to indicate item types.
The
Function sets class
has an apiType() method which you can use to determine the type
of object the MObject is referencing. Each function set also has
a type() method which can be used to determine the function set type.
The
MGlobal::getFunctionSetList() also returns an array of strings representing
the types of function sets that will accept an object.
