Usage

From source file:it.unibas.spicy.persistence.object.operators.GenerateObjectInstance.java

}

From source file:ConcurrentHashMap.java

/**
 * Return hash code for Object x. Since we are using power-of-two tables, it
 * is worth the effort to improve hashcode via the same multiplicative
 * scheme as used in IdentityHashMap./*from   ww w. ja v a  2 s  . c o  m*/
 * @param x 
 * @return hash code
 */
protected static int hash(Object x) {
    int h = x.hashCode();
    // Multiply by 127 (quickly, via shifts), and mix in some high
    // bits to help guard against bunching of codes that are
    // consecutive or equally spaced.
    return ((h << 7) - h + (h >>> 9) + (h >>> 17));
