Table 110. Set Exchange Pattern Properties

Name Description

Name	Description
`Pattern`	Specifies the exchange pattern the route will use. Valid values are: `InOnly` — consumer issues a request to a provider with no error path provided. `RobustInOnly` — consumer issues a request to a provider. The provider may respond with a fault if it fails to process request. `InOut` — consumer issues a request to a provider, with the expectation of a response. `InOptionalOut` — consumer issues a request to a provider. The provider may send a response. `OutOnly` — provider issues a request to a consumer with no error path provided. `RobustOutOnly` — provider issues a request to a consumer. The consumer may respond with a fault if it fails to process request. `OutIn` — provider issues a request to a consumer, with the expectation of a response. `OutOptionalIn` — provider issues a request to a consumer. The consumer may send a response.
`Description`	Specifies a text description for the node. This description is included in the generated XML file, but it is informational only. It is not used by Apache Camel.
`Id`	Specifies a unique identifier for the endpoint. The tooling automatically generates an id for a node when it is created, but you can remove that id or replace it with your own. The Camel debugger requires all nodes with a breakpoint set to have a unique id. You can use the id to refer to endpoints in your Camel XML file.
