Method Detail

readByte
public byte readByte() throws IOExceptionDescription copied from class:DataInputReads and returns a single byte.- Specified by:
readBytein classDataInput- Throws:
IOException- See Also:
DataOutput.writeByte(byte)
-
readBytes
public void readBytes(byte[] b, int offset, int len) throws IOExceptionDescription 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- Throws:
IOException- See Also:
DataOutput.writeBytes(byte[],int)
-
close
public void close() throws IOException- Specified by:
closein interfaceAutoCloseable- Specified by:
closein interfaceCloseable- Throws:
IOException
-
skipBytes
public void skipBytes(long numBytes) throws IOExceptionDescription 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.- Specified by:
skipBytesin classDataInput- Throws:
IOException
