Enum Class ExchangePattern

java.lang.Enum<ExchangePattern>

org.apache.camel.ExchangePattern

All Implemented Interfaces:

Serializable, Comparable<ExchangePattern>, Constable

public enum ExchangePattern
extends Enum<ExchangePattern>

The message exchange pattern of an Exchange, indicating whether the caller expects a reply.

InOnly is used for fire-and-forget messaging: the caller sends a message and does not wait for a response. InOut is used for request-reply messaging: the caller sends a message and blocks until a response is received.

The pattern is set on the Exchange and is checked by the Camel routing engine and endpoints to determine how to handle the interaction.
