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.
