Enum JournalEntryType

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<JournalEntryType>
    public enum JournalEntryType
extends java.lang.Enum<JournalEntryType>
    Types of Journal entry. This set is quite general and so not all cases may be used in practice.

    The id must be stable across new versions on the code as it ends up in the journal on-disk so we are explicit about id even though there is Enum.ordinal

      • values

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

      • valueOf

        public static JournalEntryType 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
