Constructor Details

FileBasedRegistryStoreConnector

public FileBasedRegistryStoreConnector()

Method Details

initialize

public void initialize(String connectorInstanceId,
 ConnectionProperties connectionProperties)

Initialize the connector.

Overrides:

initialize in class ConnectorBase

Parameters:

connectorInstanceId - - unique id for the connector instance - useful for messages etc

connectionProperties - - POJO for the configuration used to create the connector.

saveLocalRegistration

public void saveLocalRegistration(MemberRegistration localRegistration)

Save the local registration to the cohort registry store. This provides details of the local repository's registration with the metadata repository cohort. Any previous local registration information is overwritten.

Parameters:

localRegistration - - details of the local repository's registration with the metadata cohort.

retrieveLocalRegistration

public MemberRegistration retrieveLocalRegistration()

Retrieve details of the local registration from the cohort registry store. A null may be returned if the local registration information has not been saved (typically because this is a new server instance).

Returns:

MemberRegistration object containing details for the local repository's registration with the metadata cohort (may be null if no registration has taken place).

removeLocalRegistration

public void removeLocalRegistration()

Remove details of the local registration from the cohort registry store. This is used when the local repository unregisters from the open metadata repository cohort. There is a side-effect that all the remote registrations are removed to since the local repository is no longer a member of this cohort.

saveRemoteRegistration

public void saveRemoteRegistration(MemberRegistration remoteRegistration)

Save details of a remote registration. This contains details of one of the other repositories in the metadata repository cohort.

Parameters:

remoteRegistration - - details of a remote repository in the metadata repository cohort.

retrieveRemoteRegistrations

public List<MemberRegistration> retrieveRemoteRegistrations()

Return a list of all the remote metadata repositories registered in the metadata repository cohort.

Returns:

Remote registrations list

retrieveRemoteRegistration

public MemberRegistration retrieveRemoteRegistration(String metadataCollectionId)

Return the registration information for a specific metadata repository, identified by its metadataCollectionId. If the metadataCollectionId is not recognized then null is returned.

Parameters:

metadataCollectionId - - unique identifier for the repository

Returns:

MemberRegistration object containing details of the remote metadata repository. (null if not found)

removeRemoteRegistration

public void removeRemoteRegistration(String metadataCollectionId)

Remove details of the requested remote repository's registration from the store.

Parameters:

metadataCollectionId - - unique identifier for the repository

clearAllRegistrations

public void clearAllRegistrations()

Remove the local and remote registrations from the cohort registry store since the local server has unregistered from the cohort.

disconnect

public void disconnect()

Close the config file

Overrides:

disconnect in class ConnectorBase

close

public void close()

Flush all changes and close the registry store.
