M

Message - Interface in com.blacklocus.qs: This is a simple message abstraction.
MessageHandler<T,R> - Interface in com.blacklocus.qs: Implementations of this class perform message conversion, processing, error handling and hand off of a message retrieved from a queue.
MessageProvider - Interface in com.blacklocus.qs: Implementations of this interface provide a mechanism for retrieving messages.
MessageProviders - Class in com.blacklocus.qs: Provide some common functionality to wrap around existing MessageProvider implementations.
MessageProviders() - Constructor for class com.blacklocus.qs.MessageProviders
MessageProviders.NextCallback - Interface in com.blacklocus.qs
MessageQueueReader<T,R> - Class in com.blacklocus.qs: This class provides a general purpose "grab thing off queue and process it with threads" abstraction, decoupling the queue reading thread from the pool of processing threads.
MessageQueueReader(MessageProvider, MessageHandler<T, R>, ExecutorService) - Constructor for class com.blacklocus.qs.MessageQueueReader: Construct a new MessageQueueReader with the default idle timeout.
MessageQueueReader(MessageProvider, MessageHandler<T, R>, ExecutorService, long) - Constructor for class com.blacklocus.qs.MessageQueueReader: Construct a new MessageQueueReader with the given timeout.

N

newDefaultMessageProvider(MessageProvider, long) - Static method in class com.blacklocus.qs.MessageProviders: Chain together a safe and an empty message return tracking MessageProvider.
newDefaultMessageProvider(MessageProvider, long, int) - Static method in class com.blacklocus.qs.MessageProviders: Chain together a safe and an empty message return tracking MessageProvider.
newSafeMessageProvider(MessageProvider) - Static method in class com.blacklocus.qs.MessageProviders: Wrap each call of the given MessageProvider with a try/catch such that they always return correctly without throwing an Exception.
newUntilNextEmptyMessageProvider(MessageProvider, long) - Static method in class com.blacklocus.qs.MessageProviders: Wrap an existing MessageProvider such that after a specified number of calls to next() that results in 0 messages being returned, hasNext() flips over to return false.
newUntilNextEmptyOrMaximumMessageProvider(MessageProvider, long, int) - Static method in class com.blacklocus.qs.MessageProviders: Wrap an existing MessageProvider such that after a specified number of calls to next() that results in 0 messages being returned, or the maximum limit of messages is reached, hasNext() flips over to return false.
newUntilSlowOrMaximumMessageProvider(MessageProvider, long, int, int) - Static method in class com.blacklocus.qs.MessageProviders: Like MessageProviders.newUntilNextEmptyOrMaximumMessageProvider(MessageProvider, long, int) but instead of detecting numerous "empties" considers numerous "slows", where that is defined to be calls to next that produce less than the specified batch threshold.
next() - Method in class com.blacklocus.qs.ExternalQueueItemProvider
next(Collection<Message>) - Method in interface com.blacklocus.qs.MessageProviders.NextCallback
