Example

We want to remove a variable with key "myVar" from the exchange:

  • Java

  • XML

  • YAML

from("seda:b")
  .removeVariable("myVar")
  .to("mock:result");
<route>
  <from uri="seda:b"/>
  <removeVariable name="myVar"/>
  <to uri="mock:result"/>
</route>
- route:
    from:
      uri: seda:b
      steps:
        - removeVariable:
            name: myVar
        - to:
            uri: mock:result
If you want to remove all variables from the Exchange then use * as the name.
