Is an object a ped object?
Functions for checking whether an object is a ped() object, a singleton()
or a list of such.
is.ped(x) is.singleton(x) is.pedList(x)
x |
Any |
Note that the singleton class inherits from ped, so if x is a
singleton, is.ped(x) returns TRUE.
For is.ped(): TRUE if x is a ped or singleton object, otherwise FALSE.
For is.singleton(): TRUE if x is a singleton object, otherwise FALSE.
For is.pedList(): TRUE if x is a list of ped and/or singleton
objects, otherwise FALSE.
