Enum OMRSRegistryEventType

  • All Implemented Interfaces:
    Serializable, Comparable<OMRSRegistryEventType>
    public enum OMRSRegistryEventType
extends Enum<OMRSRegistryEventType>
implements Serializable
    OMRSRegistryEventType defines the different types of registry events in the open metadata repository services protocol. There are 4 basic values.
    • UNKNOWN_REGISTRY_EVENT: the event is not recognized by this local server, probably because it is back-level from other servers in the cohort. It is logged in the audit log and then ignored. The registration protocol should evolve so that new message types can be ignored by back-level servers without damage to the cohort's integrity.
    • REGISTRATION_EVENT: this event is a server's first contact with the cohort. It publicises the id of the local repository, the connection information needed to connect remotely to this local server's repository (localServerRemoteConnection) plus a list of typedef names and GUIDs. Other servers in the cohort will respond either with a RE_REGISTRATION_EVENT if all is ok or REGISTRATION_ERROR if there is a problem with any information in the REGISTRATION_EVENT.
    • REFRESH_REGISTRATION_EVENT: this event is used after a local server has experienced configuration issues and needs to receive the registration information from other members of the cohort again.
    • RE_REGISTRATION_EVENT: this event is used by a previously registered server to broadcast its current configuration. It is used in response to a REGISTRATION_EVENT and a REFRESH_REGISTRATION_EVENT to let the other servers know about its configuration, or whenever its configuration may have changed (such as after a server restart or administrator action).
    • UN_REGISTRATION_EVENT: this event is used when a server is being removed from the cohort. The other servers can choose whether to remove its replicated metadata from their repository, or mark it as deregistered repository's metadata.
    • REGISTRATION_ERROR_EVENT: ths event is used to report anomalies in the registration information being passed between the repositories and the actions taken. Each of these errors should be investigated since they should not occur.

    • Method Detail

      • values

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

      • valueOf

        public static OMRSRegistryEventType 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

      • getOrdinal

        public int getOrdinal()
        Return the int identifier used for indexing based on the enum.
        Returns:
        int identifier code

      • getName

        public String getName()
        Return the string name used for messages that include the enum.
        Returns:
        String name

      • getDescription

        public String getDescription()
        Return the default description for the enum value. This is used when natural resource bundle is not available.
        Returns:
        String default description
