public boolean add ( E e) [Overrides AbstractQueue] [Specified in BlockingDeque]

Inserts the specified element at the end of this deque unless it would violate capacity restrictions.

public int remainingCapacity ()

Returns the number of additional elements that this deque can ideally (in the absence of memory or resource constraints) accept without blocking.

public E remove () [Overrides AbstractQueue] [Specified in BlockingDeque]

Retrieves and removes the head of the queue represented by this deque.

public boolean remove (Object o) [Overrides AbstractCollection] [Specified in BlockingDeque]

Removes the first occurrence of the specified element from this deque.

public boolean removeAll (Collection<Object> c) [Inherited From AbstractCollection]

Removes all of this collection's elements that are also contained in the specified collection (optional operation).

public E removeFirst ()

public boolean removeFirstOccurrence (Object o) [Specified in BlockingDeque]

public E removeLast ()

public boolean removeLastOccurrence (Object o) [Specified in BlockingDeque]

pack-private boolean removeNode (Node< E> e)

Variant of removeFirstOccurrence needed by iterator.remove.

public boolean retainAll (Collection<Object> c) [Inherited From AbstractCollection]

Retains only the elements in this collection that are contained in the specified collection (optional operation).

public int size () [Specified in BlockingDeque]

Returns the number of elements in this deque.

public E take () throws InterruptedException [Specified in BlockingDeque]

public E takeFirst () throws InterruptedException [Specified in BlockingDeque]

public E takeLast () throws InterruptedException [Specified in BlockingDeque]

public Object toArray () [Overrides AbstractCollection]

Returns an array containing all of the elements in this deque, in proper sequence (from first to last element).

public T toArray ( T a) [Overrides AbstractCollection]

Returns an array containing all of the elements in this deque, in proper sequence; the runtime type of the returned array is that of the specified array.

Returns an array containing all of the elements in this deque, in proper sequence; the runtime type of the returned array is that of the specified array. If the deque fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this deque.

If this deque fits in the specified array with room to spare (i.e., the array has more elements than this deque), the element in the array immediately following the end of the deque is set to null.

Like the LinkedBlockingDeque.toArray() method, this method acts as bridge between array-based and collection-based APIs. Further, this method allows precise control over the runtime type of the output array, and may, under certain circumstances, be used to save allocation costs.

Suppose x is a deque known to contain only strings. The following code can be used to dump the deque into a newly allocated array of String:

     String[] y = x.toArray(new String[0]);

Note that toArray(new Object[0]) is identical in function to toArray().
Returns: an array containing all of the elements in this deque
Parameters:
- a - the array into which the elements of the deque are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose
Throws:
- ArrayStoreException - if the runtime type of the specified array is not a supertype of the runtime type of every element in this deque
- NullPointerException - if the specified array is null

public String toString () [Overrides AbstractCollection]
