- - ### Methods Detail

    - #### public BlockingQueue leftShift(Object value)

      Overloads the left shift operator to provide an easy way to append objects to a BlockingQueue. In case of bounded queue the method will block till space in the queue become available

          def list = new java.util.concurrent.LinkedBlockingQueue ()
          list << 3 << 2 << 1
          assert list.iterator().collect{it} == [3,2,1]

      Parameters:
        `value` - an Object to be added to the collection.
      Returns:
        same collection, after the value was added to it.
