Class PrimitiveValueProfile


  • public class PrimitiveValueProfile
    extends ValueProfile
    Represents a ValueProfile that speculates on the primitive equality or object identity of values.

    Note that for {code float} and double values we compare primitive equality via Float.floatToRawIntBits(float) and Double.doubleToRawLongBits(double), so that for example -0.0 is not considered the same as 0.0, even though primitive equality would normally say that it was.
