Method Detail

insertQuad

public void insertQuad(ProvenancedQuad provenancedQuad)

Gets called every time a quad is generated. Creates a node representing the quad. Applies the metadatageneration functions to the given quad.

Parameters:

provenancedQuad - provenanced Quad

preMappingGeneration

public void preMappingGeneration(List<Term> triplesMaps,
                                 QuadStore mappingQuads)

Generates metadata before the actual mapping.

Parameters:

triplesMaps - list of tripleMap terms

mappingQuads - mapping quadstore

postMappingGeneration

public void postMappingGeneration(String startTimestamp,
                                  String stopTimestamp,
                                  QuadStore result)

Generates metadata after the actual mapping.

Parameters:

startTimestamp - string of starting timestamp

stopTimestamp - string of stopping timestamp

result - result quadstore

getDetailLevel

public MetadataGenerator.DETAIL_LEVEL getDetailLevel()

getResult

public QuadStore getResult()
