Method Detail

baseEditorialCostForMapping

public static int baseEditorialCostForMapping(Mapping mapping,
                                              SchemaGraph sourceGraph,
                                              SchemaGraph targetGraph)

Parameters:

mapping - the mapping

sourceGraph - the source graph

targetGraph - the target graph

Returns:

the editorial cost

baseEditorialCostForMapping

public static int baseEditorialCostForMapping(Mapping mapping,
                                              SchemaGraph sourceGraph,
                                              SchemaGraph targetGraph,
                                              java.util.List<EditOperation> editOperationsResult)

Gets the "editorial cost for mapping" for the base mapping.

Use this is as base cost when invoking editorialCostForMapping(int, Mapping, SchemaGraph, SchemaGraph) as it heavily speeds up performance.

Parameters:

mapping - the mapping

sourceGraph - the source graph

targetGraph - the target graph

editOperationsResult - the list of edit operations

Returns:

the editorial cost

editorialCostForMapping

public static int editorialCostForMapping(int baseCost,
                                          Mapping mapping,
                                          SchemaGraph sourceGraph,
                                          SchemaGraph targetGraph)

Calculates the "editorial cost for mapping" for the non-fixed targets in a Mapping.

The baseCost argument should be the cost for the fixed mapping from baseEditorialCostForMapping(Mapping, SchemaGraph, SchemaGraph).

The sum of the non-fixed costs and the fixed costs is total editorial cost for mapping.

Parameters:

baseCost - the starting base cost

mapping - the mapping

sourceGraph - the source graph

targetGraph - the target graph

Returns:

the editorial cost
