public DirectoryBasedOpenMetadataArchiveStoreConnector()

Default constructor

Method Details

initialize

public void initialize(String connectorInstanceId,
 ConnectionProperties connectionProperties)

Retrieve the archive store information from the endpoint.

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.

start

public void start()
           throws ConnectorCheckedException

Indicates that the connector is completely configured and can begin processing.

getArchiveContents

public OpenMetadataArchive getArchiveContents()

Return the contents of the archive.

Specified by:

getArchiveContents in interface OpenMetadataArchiveStore

Returns:

OpenMetadataArchive object

getArchiveProperties

public OpenMetadataArchiveProperties getArchiveProperties()

Return the archive properties.

Specified by:

getArchiveProperties in interface OpenMetadataArchiveBuilder

Returns:

properties structure stored as a file encoded in JSON

setArchiveContents

public void setArchiveContents(OpenMetadataArchive archiveContents)

Set new contents into the archive. This overrides any content previously stored.

Specified by:

setArchiveContents in interface OpenMetadataArchiveStore

Parameters:

archiveContents - OpenMetadataArchive object

setArchiveProperties

public void setArchiveProperties(String archiveGUID,
 String archiveName,
 String archiveDescription,
 OpenMetadataArchiveType archiveType,
 String archiveVersion,
 String originatorName,
 String originatorLicense,
 Date creationDate,
 List<OpenMetadataArchive> dependsOnArchives)

Set up archive header and initialize the maps assuming it is building a new archive. It passes parameters used to build the open metadata archive's property header including the default license string. This determines the license and copyright for all instances in the archive that do not have their own explicit license string. The default license string will be inserted into each instance with a null license when it is loaded into an open metadata repository.

Specified by:

setArchiveProperties in interface OpenMetadataArchiveBuilder

Parameters:

archiveGUID - unique identifier for this open metadata archive.

archiveName - name of the open metadata archive.

archiveDescription - description of the open metadata archive.

archiveType - enum describing the type of archive this is.

archiveVersion - descriptive name for the version of the archive.

originatorName - name of the originator (person or organization) of the archive.

originatorLicense - default license string for content.

creationDate - data that this archive was created.

dependsOnArchives - list of archives that this archive depends on (null for no dependencies).
