Interface Predicate

    • Field Detail


        static final AttachmentKey<Map<String,​Object>> PREDICATE_CONTEXT
        Attachment key that can be used to store additional predicate context that allows the predicates to store additional information. For example a predicate that matches on a regular expression can place additional information about match groups into the predicate context. Predicates must not rely on this attachment being present, it will only be present if the predicate is being used in a situation where this information may be required by later handlers.
