Interface RandomAccessInput

All Known Implementing Classes:

BufferedIndexInput, ByteBufferIndexInput, ByteBuffersDataInput, ByteBuffersIndexInput

public interface RandomAccessInput

Random Access Index API. Unlike IndexInput, this has no concept of file position, all reads are absolute. However, like IndexInput, it is only intended for use by a single thread.

Method Summary

Modifier and Type	Method and Description
byte	readByte(long pos) Reads a byte at the given position in the file
int	readInt(long pos) Reads an integer at the given position in the file
long	readLong(long pos) Reads a long at the given position in the file
short	readShort(long pos) Reads a short at the given position in the file
