@UriEndpoint(firstVersion="2.5.0", scheme="language", title="Language", syntax="language:languageName:resourceUri", producerOnly=true, category={CORE,SCRIPT}, headersClass=LanguageConstants.class) public class LanguageEndpoint extends org.apache.camel.component.ResourceEndpoint
Execute scripts in any of the languages supported by Camel. By having a component to execute language scripts, it allows more dynamic routing capabilities. For example by using the Routing Slip or Dynamic Router EIPs you can send messages to language endpoints where the script is dynamic defined as well.
