构造器详细资料

SimpleResult

public SimpleResult(double distance,
                    int indexNumber)

Constructor for a result. The indexNumer is needed for sorting issues. Problem is that the TreeMap used for collecting the results considers equality of objects based on the compareTo function. So if an image is in the index twice, it's only found one time, the second instance -- with the same distance, but a different Lucene document -- is not added to the TreeMap at runtime as their distance between each other would be 0. This is tweaked with the running number of the document from the index, so duplicate documents that are in the index twice, appear in the result list in the order they are found in the index. See also compareTo(...) method.

参数:

distance - the actual distance to the query // * @param document the document instance form the Lucene index

indexNumber - the running number from the IndexReader. Needed for sorting issues in the result TreeMap.

方法详细资料

getDistance

public double getDistance()

setDistance

public void setDistance(double distance)

getIndexNumber

public int getIndexNumber()

compareTo

public int compareTo(SimpleResult o)

Compare the distance values to allow sorting in a tree map. If the distance value is the same, but the document is different, the index number within the index is used to distinguishing the results. Otherwise the TreeMap implementation wouldn't add the result.

指定者:

compareTo 在接口中 java.lang.Comparable<SimpleResult>

参数:

o - the SimpleResult to compare the current one to.

返回:

-1, 0, or 1

equals

public boolean equals(java.lang.Object obj)

覆盖:

equals 在类中 java.lang.Object
