Method Detail

analyze

DataSetRefs analyze(AnalysisContext context,
                    ProvenanceEventRecord event)

targetComponentTypePattern

default String targetComponentTypePattern()

Returns target component type pattern that this Analyzer supports. Note that a component type of NiFi provenance event only has processor type name without package name.

Returns:

A RegularExpression to match with a component type of a provenance event.

targetTransitUriPattern

default String targetTransitUriPattern()

Returns target transit URI pattern that this Analyzer supports.

Returns:

A RegularExpression to match with a transit URI of a provenance event.

targetProvenanceEventType

default ProvenanceEventType targetProvenanceEventType()

Returns target provenance event type that this Analyzer supports.

Returns:

A Provenance event type
