    • isLookupEvaluationAllowedInValue

      default boolean isLookupEvaluationAllowedInValue()
      True if the value() should be re-evaluated for other lookups. This is used by PropertiesLookup to allow properties to be evaluated against other properties, because the configuration properties are completely trusted and designed with lookups in mind. It is unsafe to return true in most cases because it may allow unintended lookups to evaluate other lookups.
