## 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
  Direct Known Subclasses:
    EncryptedFileSegmentInputStream

      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.
