Class FileSegmentInputStream

java.lang.Object

java.io.InputStream

org.apache.cassandra.io.util.RebufferingInputStream

org.apache.cassandra.io.util.DataInputBuffer

org.apache.cassandra.io.util.FileSegmentInputStream

All Implemented Interfaces:

java.io.Closeable, java.io.DataInput, java.lang.AutoCloseable, DataInputPlus, FileDataInput, RewindableDataInput

public class FileSegmentInputStream
extends DataInputBuffer
implements FileDataInput

This is the same as DataInputBuffer, i.e. a stream for a fixed byte buffer, except that we also implement FileDataInput by using an offset and a file path.
