- Type Parameters:
- T- the type of values to store
 - All Implemented Interfaces:
- java.lang.Iterable<T>
 
 public class ManagedConcurrentLinkedQueue<T> extends java.lang.Object implements java.lang.Iterable<T>A queue that stores values wrapped in a Reference, the type of which is determined by the providedReferenceBundle. References stored in this queue will be removed when reference processing occurs.This queue is backed by a ConcurrentLinkedQueueand is thread safe. The iterator will only return non-null values (reachable) and is based on the "weakly consistent" iterator of the underlyingConcurrentLinkedQueue.

Method Detail- 
addpublic void add(T value) Adds the specified value to the queue.- Parameters:
- value- the value to add
 
 - 
isEmptypublic boolean isEmpty() Returnstrueif this queue contains no elements.This method does not check the elements to verify they contain non-null reference values. 
 - 
toArraypublic T[] toArray(T[] tArray) Returns an array containing all values from this queue in the sequence they were added.- Parameters:
- tArray- the array to populate if big enough, else a new array with the same runtime type
- Returns:
- an array containing all non-null values in this queue
 
 - 
valuespublic java.util.List<T> values() Returns a list containing all values from this queue in the sequence they were added.
