| :page-source: core/camel-base/src/main/docs/exchangeProperty-language.adoc |
| |
| *Available as of Camel version 2.0* |
| |
| The ExchangeProperty Expression Language allows you to extract values of |
| named exchange properties. |
| |
| == Exchange Property Options |
| |
| // language options: START |
| The ExchangeProperty language supports 1 options, which are listed below. |
| |
| |
| |
| [width="100%",cols="2,1m,1m,6",options="header"] |
| |=== |
| | Name | Default | Java Type | Description |
| | trim | true | Boolean | Whether to trim the value to remove leading and trailing whitespaces and line breaks |
| |=== |
| // language options: END |
| |
| == Example usage |
| |
| The recipientList element of the Spring DSL can utilize a |
| exchangeProperty expression like: |
| |
| In this case, the list of recipients are contained in the property |
| 'myProperty'. |
| |
| [source,xml] |
| ---- |
| <route> |
| <from uri="direct:a" /> |
| <recipientList> |
| <exchangeProperty>myProperty</exchangeProperty> |
| </recipientList> |
| </route> |
| ---- |
| |
| And the same example in Java DSL: |
| |
| [source,java] |
| ---- |
| from("direct:a").recipientList(exchangeProperty("myProperty")); |
| ---- |
| |
| And with a slightly different syntax where you use the builder to the |
| fullest (i.e. avoid using parameters but using stacked operations, |
| notice that exchangeProperty is not a parameter but a stacked method |
| call) |
| |
| [source,java] |
| ---- |
| from("direct:a").recipientList().exchangeProperty("myProperty"); |
| ---- |
| |
| == Dependencies |
| |
| The ExchangeProperty language is part of *camel-core*. |
