Class NotEvaluableExpression

  • public class NotEvaluableExpression
extends java.lang.Object
    An instance of this class is used as the return value from the doNotEval SpEL helper which makes it possible to skip SpEL evaluation in other SpEL helpers e.g. toJson.

    For example, in the evaluation context is defined only fileMap object: 

    
 Map<String, Object> fileMap = Collections.singletonMap("owner", "managed-by-${team}");

    An exception will be thrown in attempt to get JSON because of fileMap contains SpEL inside. 

    
 ${#toJson(fileMap)}

    In the given case fileMap contains SpEL for another tool e.g. Terraform. Use doNotEval to let Spinnaker know that this SpEL should be evaluated by a different tool. No exceptions are thrown this way. 

    
 ${#toJson(#doNotEval(fileMap))}
