NKeys. |

| Consumer |
A Consumer in the NATS library is an object that represents an incoming queue of
messages.

|
| Dispatcher |
This library uses the concept of a Dispatcher to organize message callbacks in a way that the
application can control.
|
| ErrorListener |
This library groups problems into four categories:
Errors
The server sent an error message using the
-err protocol operation.
Exceptions
A Java exception occurred, and was handled by the library.
Slow Consumers
One of the connections consumers, Subscription or Dispatcher, is slow, and starting to drop messages.
Fast Producers
One of the connections producers is too fast, and is discarding messages
|
| FetchConsumer |
A fetch consumer gets messages by calling nextMessage.
|
| IterableConsumer | |

Subscription on a JetStream context.
|
| KeyValue |
Key Value Store Management context for creation and access to key value buckets.
|
| KeyValueManagement |
Key Value Store Management context for creation and access to key value buckets.
|
| Message |
The NATS library uses a Message object to encapsulate incoming messages.
|
| MessageConsumer |
The MessageConsumer interface is the core interface replacing
a subscription for a simplified consumer.
|
| MessageHandler |
Dispatchers use the MessageHandler interface to define the listener
for their messages. |
| ObjectStore |
Object Store Management context for creation and access to key value buckets.
|
| ObjectStoreManagement |
Object Store Management context for creation and access to object stores.
|
| OrderedConsumerContext |
The Ordered Consumer and it's context provide a simplification interface to the ordered consumer behavior.
|
| ReconnectDelayHandler |
Allows the developer to provide the duration of time to before reconnecting a second or more
time through the servers list
|
| ServerPool |
Allows the developer to provide the list of servers to try for connecting/reconnecting
|
| Statistics |
Connections can provide an instance of Statistics,
getStatistics(). |
| StatisticsCollector |
A collector for connection metrics.
|
| StreamContext |
The Stream Context provide a set of operations for managing the stream
and its contents and for managing consumers.
|
| Subscription |
A Subscription encapsulates an incoming queue of messages associated with a single
subject and optional queue name.
