## Class StringCounter

- java.lang.Object
- - org.python.core.util.StringCounter

-     public class StringCounter
      extends java.lang.Object

  Not for application use, this class may be used to count how many times a `String` occurs a point in the runtime. We use this to investigate optimisations of the handling of strings in the runtime, principally to avoid checks for byte-nature where that is already known.
