                                    double maxDistance)

ImageSearchHitsForEvaluation

public ImageSearchHitsForEvaluation(java.util.Collection<SimpleResultForEvaluation> results,
                                    double maxDistance,
                                    boolean useSimilarityScore)

Basic constructor to create results.

参数:

results -

maxDistance -

useSimilarityScore - set to true is you want similarity scores, otherwise distances will be used. Note that using distance is faster in terms of runtime.

方法详细资料

length

public int length()

Returns the size of the result list.

指定者:

length 在接口中 ImageSearchHits

返回:

the size of the result list.

score

public double score(int position)

Returns the score of the document at given position. Please note that the score in this case is a distance, which means a score of 0 denotes the best possible hit. The result list starts with position 0 as everything in computer science does.

指定者:

score 在接口中 ImageSearchHits

参数:

position - defines the position

返回:

the score of the document at given position. The lower the better (its a distance measure).

documentID

public int documentID(int position)

Returns the id of the document within the respective Lucene IndexReader

指定者:

documentID 在接口中 ImageSearchHits

参数:

position - position in the result list

返回:

the id in the IndexReader.

path

public java.lang.String path(int position)
