setBufferSize
@CanIgnoreReturnValue
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 DEFAULT_BUFFER_SIZE.
| Parameters | |
|---|---|
int bufferSize |
The buffer size in bytes. |
| Returns | |
|---|---|
CacheDataSink.Factory |
This factory. |
setCache
@CanIgnoreReturnValue
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 cache |
The cache to which data will be written. |
| Returns | |
|---|---|
CacheDataSink.Factory |
This factory. |
setFragmentSize
@CanIgnoreReturnValue
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 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 DEFAULT_FRAGMENT_SIZE.

long fragmentSize |
