Constructor Detail

CacheDataSink

public CacheDataSink(Cache cache,
                     long maxCacheFileSize)

Parameters:

cache - The cache into which data should be written.

maxCacheFileSize - The maximum size of a cache file, in bytes. If the sink is opened for a DataSpec whose size exceeds this value, then the data will be fragmented into multiple cache files.

CacheDataSink

public CacheDataSink(Cache cache,
                     long maxCacheFileSize,
                     int bufferSize)

Parameters:

cache - The cache into which data should be written.

maxCacheFileSize - The maximum size of a cache file, in bytes. If the sink is opened for a DataSpec whose size exceeds this value, then the data will be fragmented into multiple cache files.

bufferSize - The buffer size in bytes for writing to a cache file. A zero or negative value disables buffering.
