Object Hierarchy

The list below shows the inheritance tree for all FreeFlyer objects and base types. Base objects provide sets of commonly needed properties to other objects. An object that derives from a base type will inherit all the properties and methods of its base object(s). For example, at the highest level, the Object base type provides a property called "Name" to all the other objects. See the Type Casting section of the Working with Objects guide for more information on working with base types.
