Enum FetchMode

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<FetchMode>
    public enum FetchMode
extends java.lang.Enum<FetchMode>
    Represents an association fetching strategy. This is used together with the Criteria API to specify runtime fetching strategies.

    For HQL queries, use the FETCH keyword instead.
    See Also:
    Criteria.setFetchMode(java.lang.String, FetchMode)

    • Method Detail

      • values

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

      • valueOf

        public static FetchMode valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
