Method Detail

isCachedFileExists

public boolean isCachedFileExists()

getFile

public java.io.File getFile()

This method returns direct cached File instance. It marks cache unit with that information thus any possible eviction to that unit will write special zero-bytes marker file in cache folder and will NOT remove file itself. All marked cache files will be removed on next system restart or may be removed by system administrator manually. Remember that in case of getting cache files as regular File instances may exceed declared cache size due to evictions.

Returns:

cached file instance

getStream

public java.io.InputStream getStream()

markResourceAsEvicted

public void markResourceAsEvicted()

releaseUsageAndRemoveIfMarked

protected void releaseUsageAndRemoveIfMarked()

tryRemoveResourceOrWriteEvictedMarker

public void tryRemoveResourceOrWriteEvictedMarker()

removeResource

protected void removeResource()

Removes resource without any checks. Unsafe and not thread safe!

getWeight

public int getWeight()

convertNumBytesToCacheUnitWeight

public static int convertNumBytesToCacheUnitWeight(long numBytes)
