public synchronized void invalidateClasses(Collection<String> classNames) {
    if (classNames.isEmpty())
        return;
    SwitchPoint[] points = new SwitchPoint[classNames.size()];
    int i = 0;
    for (String className : classNames) {
        SwitchPoint switchPoint = switchPoints.put(className, null);
        if (switchPoint == null)
            switchPoint = DUMMY;
        points[i++] = switchPoint;
    }
    SwitchPoint.invalidateAll(points);
}

Example 2 with SwitchPoint

private T replacePayLoad() {
    T payload = valueSupplier.get();
    MethodHandle ref = MethodHandles.constant(clazzRef.get(), payload);
    SwitchPoint sp = validationSupplier.apply(payload);
    returnRef = sp.guardWithTest(ref, FALLBACK_HANDLE);
    return payload;
}
