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

Constructor Details- 
ManagedConcurrentLinkedQueueCreates an empty ManagedConcurrentLinkedQueue that will use the providedReferenceBundleto store values as the given Reference type.- Parameters:
- bundle- used to create the appropriate Reference type for the values stored
 
 
- 
- 
Method Details- 
addAdds 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. 
- 
toArrayReturns 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
 
- 
valuesReturns a list containing all values from this queue in the sequence they were added.
- 
iteratorReturns an iterator over all non-null values in this queue. The values should be returned in the order they were added.
