Class StringCounter

java.lang.Object
org.python.core.util.StringCounter
public class StringCounter extends 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.
