Method Details
-
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. -
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. -
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.
