List of drainTo() Examples

Examples of drainTo()

com.hazelcast.core.IQueue.drainTo()
{@inheritDoc}
java.util.concurrent.BlockingQueue.drainTo()
Removes all available elements from this queue and adds them to the given collection. This operation may be more efficient than repeatedly polling this queue. A failure encountered while attempting to add elements to collection {@code c} may result in elements being in neither,either or both collections when the associated exception is thrown. Attempts to drain a queue to itself result in {@code IllegalArgumentException}. Further, the behavior of this operation is undefined if the specified collection is modified while the operation is in progress. @param c the collection to transfer elements into @return the number of elements transferred @throws UnsupportedOperationException if addition of elementsis not supported by the specified collection @throws ClassCastException if the class of an element of this queueprevents it from being added to the specified collection @throws NullPointerException if the specified collection is null @throws IllegalArgumentException if the specified collection is thisqueue, or some property of an element of this queue prevents it from being added to the specified collection
