private static final ThreadLocal<CollectionsFactory.Mode> tl

getMode
```
public static CollectionsFactory.Mode getMode()
```
Gets the current mode determining the type of collection objects created by this factory.

public static <K,V> HashMap<K,V> newMap()

public static <K,V> HashMap<K,V> newMap(Map<K,V> m)

public static <K,V> HashMap<K,V> newMap(int initialCapacity)

public static <K,V> Map<K,V> newIdentityMap()

public static <K,V> Map<K,V> newIdentityMap(int expectedMaxSize)

public static <K,V> Map<K,V> newIdentityMap(Map<K,V> m)

newSet
```
public static <E> Set<E> newSet()
```
Creates a set. If the current thread is using CollectionsFactory.Mode.DETERMINISTIC_ITERATION_ORDER collections, the returned set will have an iteration order determined by the order in which elements are inserted in the set.
