10. Objects

The GENESIS distribution contains a large number of predefined element types, known as ``objects''. These are the templates from which simulation elements may be created.

The following objects are currently available as part of GENESIS:

10.2 Related Commands

The GENESIS routines used to establish and work with objects include the following. (Remember: the following routines refer to these element types in general, not specific instantiations of these objects).

Routine	Description
getdefault	Returns the default value of an object field.
setdefault	Sets the default value of an object field.
showobject	Displays description of specified object.
listobjects	Lists available objects.
listactions	Lists the actions which are defined for GENESIS objects.
listclasses	Displays list of currently defined element classes.

In addition, there are a number of routines which are used in the specification and creation of Extended Objects. To compile a new object into GENESIS, see Customizing GENESIS.
