int order
        Deprecated.
        use declaration order instead. Will get removed in the next release.
        The order has no effect anymore. The declaration order specialization methods is used instead.
        Default:
        -1

      • insertBefore

        java.lang.String insertBefore
        Inserts this and all specializations that are declared after this specialization before a specialization in the superclass. By default all specializations of the subclass are appended to the specializations of the superclass.
        Default:
        ""

      • rewriteOn

        java.lang.Class<? extends java.lang.Throwable>[] rewriteOn
        Default:
        {}

      • contains

        java.lang.String[] contains
        The contains attribute declares all specializations that are contained by this specialization. A containing specialization must be strictly generic as the contained specialization.
        Default:
        {}

      • guards

        java.lang.String[] guards
        Default:
        {}

      • assumptions

        java.lang.String[] assumptions
        Defines the assumptions to check for this specialization. When the specialization method is invoked it is guaranteed that these assumptions still hold. It is not guaranteed that they are checked before the guards() methods. They may be checked before after or in between guards(). To declare assumptions use the NodeAssumptions annotation at class level.
        Default:
        {}
