Type Parameters:

T - the type of the messages's payload

All Superinterfaces:

java.util.function.Consumer<Message<T>>

All Known Implementing Classes:

MethodInvokingMessageConsumer, StatefulMessageConsumer
```
@ThreadSafe
public interface MessageConsumer<T>
extends java.util.function.Consumer<Message<T>>
```
A consumer endpoint for messages with payload-type <T>.

Multiple EventConsumers may listen at a single EventSource. A single EventConsumer must be registered to multiple EventSources.

By default, Synapse is auto-configuring a EventSourceConsumerProcess that is running a separate thread for every MessageConsumer. The thread is taking care for continuous consumption of messages using the consumers, until the application is shutting down.

If you need to manually consume messages using MessageConsumers, auto-configuration of the EventSourceConsumerProcess can be disabled by setting synapse.consumer-process.enabled=false

MessageConsumers are expected to be thread-safe.
