Imports
org.antlr.v4.runtime.misc.IntervalSet
Utility class to create AtomTransition, RangeTransition, and SetTransition appropriately based on the range of the input. To keep the serialized ATN size small, we only inline atom and range transitions for Unicode code points <= U+FFFF. Whenever we encounter a Unicode code point > U+FFFF, we represent that as a set transition (even if it is logically an atom or a range).
