evaluator
Type:
expressionFilterEvaluators
Use:
optional
The expression evaluator to use. The expression filter supports some types such as header, payload, exception, wildcard, and regex, that are built-in filters not registered with the ExpressionEvaluatorManager. All others are registered with the ExpressionEvaluatorManager. Where XPath, bean, and ONGL are used, the expression should be a boolean expression.

Enumeration:
 "header", "payload-type", "exception-type", "wildcard", "regex", "ognl", "xpath", "jxpath", "groovy", "bean", "custom", "registry", "variable"

<xsd:attribute name="evaluator" type="expressionFilterEvaluators" use="optional"/>

Type:

Use:
required
The expression that will be evaluated. This should always be a boolean expression. The syntax of the expression will be determined by the expression language being used.
