Remarks
An unbounded concurrent Deque deque based on linked nodes. Concurrent insertion, removal, and access operations execute safely across multiple threads. A ConcurrentLinkedDeque is an appropriate choice when many threads will share access to a common collection. Like most other concurrent collection implementations, this class does not permit the use of null elements.
Iterators and spliterators are <i>weakly consistent</i>.
Beware that, unlike in most collections, the size method is <em>NOT</em> a constant-time operation. Because of the asynchronous nature of these deques, determining the current number of elements requires a traversal of the elements, and so may report inaccurate results if this collection is modified during traversal.
Bulk operations that add, remove, or examine multiple elements, such as #addAll, #removeIf or #forEach, are <em>not</em> guaranteed to be performed atomically. For example, a forEach traversal concurrent with an addAll operation might observe only some of the added elements.
This class and its iterator implement all of the <em>optional</em> methods of the Deque and Iterator interfaces.
Memory consistency effects: As with other concurrent collections, actions in a thread prior to placing an object into a ConcurrentLinkedDeque<i>happen-before</i> actions subsequent to the access or removal of that element from the ConcurrentLinkedDeque in another thread.
This class is a member of the Java Collections Framework.

Constructors
| ConcurrentLinkedDeque() |
Constructs an empty deque. |
| ConcurrentLinkedDeque(ICollection) |
Constructs a deque initially containing the elements of the given collection, added in traversal order of the collection's iterator. |
| ConcurrentLinkedDeque(IntPtr, JniHandleOwnership) |
A constructor used when creating managed representations of JNI objects; called by the runtime. |
