Method Detail

initialize

public void initialize(String connectorInstanceId,
                       ConnectionProperties connectionProperties)

Initialize the connector.

Overrides:

initialize in class MainGraphConnectorBase

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.

Specified by:

start in interface OpenLineageGraphStore

Overrides:

start in class MainGraphConnectorBase

Throws:

ConnectorCheckedException - there is a problem within the connector.

addEntity

public void addEntity(LineageEvent lineageEvent)

Specified by:

addEntity in interface MainGraph

Overrides:

addEntity in class MainGraphConnectorBase

lineage

public LineageResponse lineage(String graphName,
                               Scope scope,
                               View view,
                               String guid)

Returns a lineage subgraph.

Specified by:

lineage in interface MainGraph

Overrides:

lineage in class MainGraphConnectorBase

Parameters:

graphName - main, buffer, mock, history.

scope - source-and-destination, end-to-end, ultimate-source, ultimate-destination, glossary.

view - The view queried by the user: hostview, tableview, columnview.

guid - The guid of the node of which the lineage is queried from.

Returns:

A subgraph containing all relevant paths, in graphSON format.

dumpGraph

public void dumpGraph(String graphName)

Write an entire graph to disc in the Egeria root folder, in the .GraphMl format.

Specified by:

dumpGraph in interface MainGraph

Overrides:

dumpGraph in class MainGraphConnectorBase

Parameters:

graphName - MAIN, BUFFER, MOCK, HISTORY.

exportGraph

public String exportGraph(String graphName)

Return an entire graph, in GraphSon format.

Specified by:

exportGraph in interface MainGraph

Overrides:

exportGraph in class MainGraphConnectorBase

Parameters:

graphName - MAIN, BUFFER, MOCK, HISTORY.

Returns:

The queried graph, in graphSON format.

getMainGraph

public Object getMainGraph()

Specified by:

getMainGraph in interface MainGraph

Overrides:

getMainGraph in class MainGraphConnectorBase
