+<div class="block"><p>
+ BlockingEnvelopeMap is a helper class for SystemConsumer implementations.
+ Samza's poll() requirements make implementing SystemConsumers somewhat
+ tricky. BlockingEnvelopeMap is provided to help other developers write
+ SystemConsumers. The intended audience is not those writing Samza jobs, but
+ rather those extending Samza to consume from new types of stream providers
+ and other systems.
+ </p>
+
+ <p>
+ SystemConsumers that implement BlockingEnvelopeMap need to add messages using
+ <a href="../../../../org/apache/samza/util/BlockingEnvelopeMap.html#put(org.apache.samza.system.SystemStreamPartition,%20org.apache.samza.system.IncomingMessageEnvelope)"><code>put</code></a>
+ (or <a href="../../../../org/apache/samza/util/BlockingEnvelopeMap.html#putAll(org.apache.samza.system.SystemStreamPartition,%20java.util.List)"><code>putAll</code></a>),
+ and update noMoreMessage using setIsAtHead. The noMoreMessage variable is used
+ to determine whether a SystemStreamPartition is "caught up" (has read all
+ possible messages from the underlying system). For example, with a Kafka
+ system, noMoreMessages would be set to true when the last message offset
+ returned is equal to the offset high watermark for a given topic/partition.
+ </p>
+ The BlockingEnvelopeMap is backed by a concurrent map, which allows concurrent
+ put or putAll calls to be thread safe without external synchronization.</div>
