java.lang.Object

net.semanticmetadata.lire.indexers.tools.ProximityHashingIndexor

public class ProximityHashingIndexor
extends java.lang.Object

The Indexor (yes, I know the hashFunctionsFileName sounds weird, but it should match the Extractor class, and not the Lucene Indexing classes) reads data files created by the Extractor. They are added to a given index. Note that the index is not overwritten, but the documents are appended. This one implements the proximity approach "metric spaces" based on the work of Giuseppe Amato. See Gennaro, Claudio, et al. "An approach to content-based image retrieval based on the Lucene search engine library." Research and Advanced Technology for Digital Libraries. Springer Berlin Heidelberg, 2010. 55-66.

方法详细资料

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException,
                        java.lang.IllegalAccessException,
                        java.lang.InstantiationException

抛出:

java.io.IOException

java.lang.IllegalAccessException

java.lang.InstantiationException

isConfigured

protected boolean isConfigured()

printHelp

protected static void printHelp()

Just prints help.

setFeatureClass

public void setFeatureClass(java.lang.Class featureClass)

run

public void run()

addToDocument

protected void addToDocument(GlobalFeature feature,
                             org.apache.lucene.document.Document document,
                             java.lang.String featureFieldName)

Overwrite this method if you want to filter the input, apply hashing, etc.

参数:

feature - the current feature.

document - the current document.

featureFieldName - the field hashFunctionsFileName of the feature.

addInputFile

public void addInputFile(java.io.File inputFile)

setIndexPath

public void setIndexPath(java.lang.String indexPath)
