### createSimilarCollection

    protected static Collection createSimilarCollection(Collection collection)

### createSimilarCollection

    protected static Collection createSimilarCollection(Collection collection,
                                                        int newCapacity)

### createSimilarList

    protected static List createSimilarList(List left,
                                            int newCapacity)

### cloneSimilarMap

### createSimilarSet

    protected static Set createSimilarSet(Set self)

### sameType

    protected static boolean sameType(Collection[] cols)
