Getters and Setters should be implemented so the output of a getter can be used as input to a setter. This lets us write code like this:
a.setFoo( b.getFoo() )
Another common programming idiom that relies on getters and setter co-operating looks like this:
old_value = a.getFoo() # save old state a.setFoo( new_val ) # new state ## do something a.setFoo( old_value ) # restore initial state
If your get/set pair is commonly used like this, consider having the setter return the current state:
old_value = a.setFoo( new_val ) ## do something a.setFoo( old_value )
If you are writing a sexy, modern Bpy type, you could write a tp_getattr handler using a PyMethodDef table. See [] for more information.
