Enum DomainAccessType

    • Enum Constant Detail

      • REFLECTION

        public static final DomainAccessType REFLECTION
        Use reflection to read/write members (fields and methods) of the domain.

        When used in a modulepath, the module must be open. When used in GraalVM, the domain must be open for reflection.

        This is the default, except with optaplanner-quarkus.

      • GIZMO

        public static final DomainAccessType GIZMO
        Use Gizmo generated bytecode to access members (fields and methods) to avoid reflection for additional performance.

        With optaplanner-quarkus, this bytecode is generated at build time and it supports planning annotations on non-public members too.

        Without optaplanner-quarkus, this bytecode is generated at bootstrap runtime and you must add Gizmo in your classpath or modulepath and use planning annotations on public members only.

    • Method Detail

      • values

        public static DomainAccessType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (DomainAccessType c : DomainAccessType.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static DomainAccessType valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
