org.odpi.openmetadata.repositoryservices.events.OMRSRegistryEvent

public class OMRSRegistryEvent
extends OMRSEvent

OMRSRegistryEvent provides the conversion between the properties of a registry event and the serialized event body. It supports conversion in either direction through its inner class called OMRSRegistryEventPayload:

• Converting from registry event properties to an OMRSEvent body for sending outbound events.
• Converting from an event body to registry event properties for inbound events.

OMRSRegistryEvent also provides a specialized interface to allow the cohort registry to work effectively with registry events.

registryEventType - type of event (REGISTRATION_EVENT, REFRESH_REGISTRATION_REQUEST, RE_REGISTRATION_EVENT)

registrationTimestamp - time that the local repository registered.

metadataCollectionName - name of the metadata collection being registered.

remoteConnection - remote connection to this local repository.

OMRSRegistryEvent

public OMRSRegistryEvent(OMRSRegistryEventType registryEventType)

Constructor for an UnRegistration Event.

Parameters:

registryEventType - the type of event

OMRSRegistryEvent

public OMRSRegistryEvent(OMRSRegistryEventErrorCode errorCode,
 String errorMessage,
 String targetMetadataCollectionId,
 Connection remoteConnection)

Constructor for the REGISTRATION_ERROR_EVENT outbound event.

Parameters:

errorCode - detailed error code

errorMessage - Optional error message

targetMetadataCollectionId - the identifier of the server that sent bad information.

remoteConnection - remote connection to the target repository. (Optional only supplied if relevant to the reported error; otherwise null.)

Method Details

getRegistryEventType

public OMRSRegistryEventType getRegistryEventType()

Return the specific registry event type.

Returns:

registry event type enum

getRegistrationTimestamp

public Date getRegistrationTimestamp()

Return the date/time that the repository registered with the open metadata repository cohort. If this is a normal registry event then this timestamp is the registration time for the local repository. If this an error event, then this is the registration time for the target repository.

Returns:

Connection object

getErrorCode

public OMRSRegistryEventErrorCode getErrorCode()

Return the error code for the event. This property is only used for error events.

Returns:

OMRSRegistryEventErrorCode enum

getOMRSEventV1
