Overview

for CacheDataSink instances.

Summary

Constructors

Creates an instance.

Methods

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.

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.

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.
