Method Detail
-
clone
public PagedBytes.PagedBytesDataInput clone()
Description copied from class:DataInputReturns a clone of this stream.Clones of a stream access the same data, and are positioned at the same point as the stream they were cloned from.
Expert: Subclasses must ensure that clones may be positioned at different points in the input from each other and from the stream they were cloned from.
-
getPosition
public long getPosition()
Returns the current byte position.
-
setPosition
public void setPosition(long pos)
Seek to a position previously obtained fromgetPosition().
-
readByte
public byte readByte()
Description copied from class:DataInputReads and returns a single byte.- Specified by:
readBytein classDataInput- See Also:
DataOutput.writeByte(byte)
-
readBytes
public void readBytes(byte[] b, int offset, int len)Description copied from class:DataInputReads a specified number of bytes into an array at the specified offset.- Specified by:
readBytesin 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)
-
skipBytes
public void skipBytes(long numBytes)
Description copied from class:DataInputSkip overnumBytesbytes. This method may skip bytes in whatever way is most optimal, and may not have the same behavior as reading the skipped bytes. In general, negativenumBytesare not supported.
