Regular API function

simIsHandle / sim.isHandle

Description Checks whether a general object handle is still valid. When a general object is destroyed (e.g. programmatically or via the user interface), then its related handle is not valid anymore and will trigger an error when used. Use this function to avoid triggering an error. See also sim.getObject.
