Class CachedCommonProperties

java.lang.Object
  org.aksw.commons.jena.util.CachedCommonProperties

@Guarded(applyFieldConstraintsToConstructors=true)
public class CachedCommonProperties
extends Object

Cached version of CommonProperties. The constructor tries to load the cache from the given file. If the file does not exist, an empty cache is created and filled with every cache miss. Call save() to write the cache on disk. Set offline to true if you want to use the cached values only. Values from the cache are used regardless of the original parameters for threshold, endpoint and sampleSize.
