Enum SqmJoinType

  • All Implemented Interfaces:
    Serializable, Comparable<SqmJoinType>

    public enum SqmJoinType
    extends Enum<SqmJoinType>
    Represents a canonical join type.

    Note that currently HQL really only supports inner and left outer joins (though cross joins can also be achieved). This is because joins in HQL are always defined in relation to a mapped association. However, when we start allowing users to specify ad-hoc joins this may need to change to allow the full spectrum of join types. Thus the others are provided here currently just for completeness and for future expansion.

      • INNER

        public static final SqmJoinType INNER
        Represents an inner join.
      • LEFT

        public static final SqmJoinType LEFT
        Represents a left outer join.
      • RIGHT

        public static final SqmJoinType RIGHT
        Represents a right outer join.
      • CROSS

        public static final SqmJoinType CROSS
        Represents a cross join (aka a cartesian product).
      • FULL

        public static final SqmJoinType FULL
        Represents a full join.
    • Method Detail

      • values

        public static SqmJoinType[] 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 (SqmJoinType c : SqmJoinType.values())
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static SqmJoinType 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.)
        name - the name of the enum constant to be returned.
        the enum constant with the specified name
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
