Constructor Detail

• Factory

  public Factory()

  Creates an instance.

Method Detail

• setCache

  public CacheDataSink.Factory setCache(Cache cache)

  Sets the cache to which data will be written.

  Must be called before the factory is used.

  Parameters:

  cache - The cache to which data will be written.

  Returns:

  This factory.

• setFragmentSize

  public CacheDataSink.Factory setFragmentSize(long fragmentSize)

  Sets the cache file fragment size. For requests that should be fragmented into multiple cache files, this is the maximum size of a cache file in bytes. If set to C.LENGTH_UNSET then no fragmentation will occur. Using a small value allows for finer-grained cache eviction policies, at the cost of increased overhead both on the cache implementation and the file system. Values under (2 * 1024 * 1024) are not recommended.

  The default value is CacheDataSink.DEFAULT_FRAGMENT_SIZE.

  Parameters:

  fragmentSize - The fragment size in bytes, or C.LENGTH_UNSET to disable fragmentation.

  Returns:

  This factory.

• setBufferSize

  public CacheDataSink.Factory setBufferSize(int bufferSize)

  Sets the size of an in-memory buffer used when writing to a cache file. A zero or negative value disables buffering.

  The default value is CacheDataSink.DEFAULT_BUFFER_SIZE.

  Parameters:

  bufferSize - The buffer size in bytes.

  Returns:

  This factory.
