Class SplitFileSegmentKeys

java.lang.Object

freenet.client.async.SplitFileSegmentKeys

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class SplitFileSegmentKeys
extends java.lang.Object
implements java.lang.Cloneable, java.io.Serializable

Contains the keys for a splitfile segment, in an efficient compressed form. These are not changed, so the object never needs to be stored once created; this is good as it is fairly large. SplitFileFetcherSegment keeps the data on which keys have been used separately and passes it in. We will auto-upgrade SplitFileFetcherSegment's to use SplitFileSegmentKeys in the caller.
