method slice(parstart: dynamic; parend: dynamic; parcontentType: dynamic): dynamic

dynamic slice(dynamic parstart, dynamic parend, dynamic parcontentType)

func slice(_ parstart: dynamic, _ parend: dynamic, _ parcontentType: dynamic) -> dynamic

dynamic slice(dynamic parstart, dynamic parend, dynamic parcontentType)

Function slice(parstart As dynamic, parend As dynamic, parcontentType As dynamic) As dynamic
