close
public void close()
Description copied from class:IndexInput
Closes the stream to further operations.- Specified by:
close
in interfacejava.lang.AutoCloseable
- Specified by:
close
in interfacejava.io.Closeable
- Specified by:
close
in classIndexInput
-
getFilePointer
public long getFilePointer()
Description copied from class:IndexInput
Returns the current position in this file, where the next read will occur.- Specified by:
getFilePointer
in classIndexInput
- See Also:
IndexInput.seek(long)
-
length
public long length()
Description copied from class:IndexInput
The number of bytes in the file.- Specified by:
length
in classIndexInput
-
readByte
public byte readByte()
Description copied from class:DataInput
Reads and returns a single byte.- Specified by:
readByte
in classDataInput
- See Also:
DataOutput.writeByte(byte)
-
readBytes
public void readBytes(byte[] b, int offset, int len)
Description copied from class:DataInput
Reads a specified number of bytes into an array at the specified offset.- Specified by:
readBytes
in classDataInput
- Parameters:
b
- the array to read bytes intooffset
- the offset in the array to start storing byteslen
- the number of bytes to read- See Also:
DataOutput.writeBytes(byte[],int)
