EDU.oswego.cs.dl.util.concurrent.Slot.poll()
co.cask.cdap.data2.transaction.stream.StreamConsumer.poll()

{@inheritDoc}
com.netflix.servo.publish.JmxMetricPoller.poll()
{@inheritDoc}
com.netflix.servo.publish.MetricPoller.poll()
Fetch the current values for a set of metrics that match the provided filter. This method should be cheap, thread-safe, and interruptible so that it can be called frequently to collect metrics at a regular interval. @param filter retricts the set of metrics @return list of current metric values
com.netflix.suro.input.thrift.MessageSetProcessor.poll()
com.opengamma.engine.view.execution.ViewCycleExecutionSequence.poll()
Gets the next execution options in the sequence. This is a destructive operation; it should be used only when intending to begin a view cycle with the options returned. @param defaultExecutionOptions the default execution options, may be null @return the execution options for the next cycle, null if there are no further cycles to execute
com.vividsolutions.jts.util.PriorityQueue.poll()
Remove the smallest item from the priority queue. @return the smallest item. @return null if empty

Convenience method for the caller to handle the backward compatibility between pre 1.345 SCMs.
io.thp.psmove.PSMove.poll()
java.lang.ref.ReferenceQueue.poll()
Polls this queue to see if a reference object is available. If one is available without further delay then it is removed from the queue and returned. Otherwise this method immediately returns null. @return A reference object, if one was immediately available,otherwise null
java.nio.file.WatchService.poll()
Retrieves and removes the next watch key, or {@code null} if none arepresent. @return the next watch key, or {@code null} @throws ClosedWatchServiceException if this watch service is closed
java.util.ArrayDeque.poll()
Retrieves and removes the head of the queue represented by this deque (in other words, the first element of this deque), or returns null if this deque is empty.
This method is equivalent to {@link #pollFirst}. @return the head of the queue represented by this deque, ornull if this deque is empty
java.util.LinkedList.poll()

java.util.PriorityQueue.poll()
java.util.Queue.poll()
Retrieves and removes the head of this queue, or returns null if this queue is empty. @return the head of this queue, or null if this queue is empty
java.util.concurrent.ArrayBlockingQueue.poll()
java.util.concurrent.BlockingQueue.poll()
Retrieves and removes the head of this queue, waiting up to the specified wait time if necessary for an element to become available. @param timeout how long to wait before giving up, in units of{@code unit} @param unit a {@code TimeUnit} determining how to interpret the{@code timeout} parameter @return the head of this queue, or {@code null} if thespecified waiting time elapses before an element is available @throws InterruptedException if interrupted while waiting
java.util.concurrent.ConcurrentLinkedQueue.poll()
java.util.concurrent.ExecutorCompletionService.poll()
java.util.concurrent.LinkedBlockingDeque.poll()
java.util.concurrent.LinkedBlockingQueue.poll()
net.java.games.input.Controller.poll()

org.apache.oozie.event.EventQueue.poll()
Fetch single event from queue @return event
org.apache.synapse.message.store.MessageStore.poll()
Retrieves and removes the first Message in this store. Message ordering will depend on the underlying implementation @return first message context in the store
