Uses of Queue in java.util

Subinterfaces of Queue in java.util

Modifier and Type	Interface	Description
interface	Deque<E>	A linear collection that supports element insertion and removal at both ends.

Classes in java.util that implement Queue

Modifier and Type	Class	Description
class	AbstractQueue<E>	This class provides skeletal implementations of some Queue operations.
class	ArrayDeque<E>	Resizable-array implementation of the Deque interface.
class	LinkedList<E>	LinkedList is an implementation of List, backed by a doubly-linked list.
class	PriorityQueue<E>	A PriorityQueue holds elements on a priority heap, which orders the elements according to their natural order or according to the comparator specified at construction time.

Methods in java.util that return Queue

Modifier and Type	Method	Description
static <T> Queue<T>	Collections.asLifoQueue(Deque<T> deque)	Returns a last-in, first-out queue as a view of deque.

Uses of Queue in java.util.concurrent

Subinterfaces of Queue in java.util.concurrent

Modifier and Type	Interface	Description
interface	BlockingDeque<E>	A Deque that additionally supports blocking operations that wait for the deque to become non-empty when retrieving an element, and wait for space to become available in the deque when storing an element.
interface	BlockingQueue<E>	A Queue that additionally supports operations that wait for the queue to become non-empty when retrieving an element, and wait for space to become available in the queue when storing an element.
interface	TransferQueue<E>	A BlockingQueue in which producers may wait for consumers to receive elements.

Classes in java.util.concurrent that implement Queue

Modifier and Type	Class	Description
class	ArrayBlockingQueue<E>	A bounded blocking queue backed by an array.
class	ConcurrentLinkedDeque<E>	An unbounded concurrent deque based on linked nodes.
class	ConcurrentLinkedQueue<E>	An unbounded thread-safe queue based on linked nodes.
class	DelayQueue<E extends Delayed>	An unbounded blocking queue of Delayed elements, in which an element can only be taken when its delay has expired.
class	LinkedBlockingDeque<E>	An optionally-bounded blocking deque based on linked nodes.
class	LinkedBlockingQueue<E>	An optionally-bounded blocking queue based on linked nodes.
class	LinkedTransferQueue<E>	An unbounded TransferQueue based on linked nodes.
class	PriorityBlockingQueue<E>	An unbounded blocking queue that uses the same ordering rules as class PriorityQueue and supplies blocking retrieval operations.
class	SynchronousQueue<E>	A blocking queue in which each insert operation must wait for a corresponding remove operation by another thread, and vice versa.

Uses of Queue in org.apache.http.impl.conn.tsccm

Fields in org.apache.http.impl.conn.tsccm declared as Queue

Modifier and Type	Field	Description
protected Queue<BasicPoolEntry>	ConnPoolByRoute.freeConnections	The list of free connections
protected Queue<WaitingThread>	ConnPoolByRoute.waitingThreads	The list of WaitingThreads waiting for a connection
protected Queue<WaitingThread>	RouteSpecificPool.waitingThreads	The list of threads waiting for this pool.

Methods in org.apache.http.impl.conn.tsccm that return Queue

Modifier and Type	Method	Description
protected Queue<BasicPoolEntry>	ConnPoolByRoute.createFreeConnQueue()	Creates the queue for ConnPoolByRoute.freeConnections.
protected Queue<WaitingThread>	ConnPoolByRoute.createWaitingThreadQueue()	Creates the queue for ConnPoolByRoute.waitingThreads.
