Constructor Detail

ComparisonResult

public ComparisonResult(ComparisonResult.Type type,
                int[] indexMap)

Method Detail

getIndexMap

public int[] getIndexMap()

Returns:

mapping of indices of parameter extractor to this extractor. E.g. extractors arg[0] < arg[1] and arg[1] > arg[0] are equal with index mapping {1, 0}. null is returned for no mapping (if extractors are NOT_EQUAL) and for 1 to 1 mapping. In other words, if cr = e1.compareTo(e2), then new MappedExtractor(e1, cr.getIndexMap()).compareTo(e2).isOneToOneMapping()==true or return value of new MappedExtractor(e1, cr.getIndexMap()).extract() is the same as of e2.extract()

getType

public ComparisonResult.Type getType()

isOneToOneMapping

public boolean isOneToOneMapping()

isOneToOneMapping

public static boolean isOneToOneMapping(int[] map)

compareIndexMaps

public boolean compareIndexMaps(int[] otherIndexMap)

toString

public String toString()

Overrides:

toString in class Object

inverse

public static int[] inverse(int[] map,
            Set<Integer> parameterIndices)

Inverses index map.

Parameters:

indexMap2 -

Returns:

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
