Method Detail

getMapping

AMapping getMapping(ACache source,
                    ACache target,
                    String sourceVar,
                    String targetVar,
                    String expression,
                    double threshold)

Returns a mapping given a source, a target knowledge base and a link specification.

Parameters:

source - source cache

target - target cache

sourceVar - source property variable

targetVar - size property variable

expression - metric expression of link specification

threshold - threshold of link specification

Returns:

a mapping, the resulting mapping

getRuntimeApproximation

double getRuntimeApproximation(int sourceSize,
                               int targetSize,
                               double theta,
                               IMapper.Language language)

Returns the estimated time needed to obtain the mapping computed by the mapper.

Parameters:

sourceSize - source size

targetSize - target size

theta - atomic specification threshold

language - language of source and target variables

Returns:

estimated runtime, as double

getMappingSizeApproximation

double getMappingSizeApproximation(int sourceSize,
                                   int targetSize,
                                   double theta,
                                   IMapper.Language language)

Returns the estimated mapping size of the mapping computed by the mapper.

Parameters:

sourceSize - source size

targetSize - target size

theta - atomic specification threshold

language - language of source and target variables

Returns:

estimated execution time, as double

getName

String getName()

Returns the name of the mapper.

Returns:

Mapper name as a string
