public NOWRadheader()

Method Detail

isValidFile

public boolean isValidFile(RandomAccessFile raf)

check if this file is a nids / tdwr file

Parameters:

raf - input file

Returns:

true if valid

getData

public byte[] getData(int offset)
               throws Exception

Throws:

Exception

setProperty

public void setProperty(String name,
                        String value)

shortsToInt

public static int shortsToInt(short s1,
                              short s2,
                              boolean swapBytes)

convert two short into a integer

Parameters:

s1 - short one

s2 - short two
