Enum ConstructorEntityArgumentMode

  • All Implemented Interfaces:
    Serializable, Comparable<ConstructorEntityArgumentMode>
    public enum ConstructorEntityArgumentMode
extends Enum<ConstructorEntityArgumentMode>
    Describes the allowable ways in which entity references can be handled as dynamic-instantiation (ctor result) argument.

    NOTE that this only applies to Hibernate extension to JPA. JPA does not allow ctor-result arguments to be anything other than scalar values (column result).

    • Enum Constant Detail

      • SCALAR

        public static final ConstructorEntityArgumentMode SCALAR
        The id of the entity will be used as the ctor arg. This is the legacy Hibernate behavior.

      • ENTITY

        public static final ConstructorEntityArgumentMode ENTITY
        The entity reference will be passed as the ctor arg. Whether the entity ref is initialized or not depends on whether the entity is fetched in the query or is otherwise already part of the persistence context.

      • CHOOSE

        public static final ConstructorEntityArgumentMode CHOOSE
        This mode says to chose based on what ctors are available on the target class.

    • Method Detail

      • values

        public static ConstructorEntityArgumentMode[] 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 (ConstructorEntityArgumentMode c : ConstructorEntityArgumentMode.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static ConstructorEntityArgumentMode 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
