NOWRadheader

public NOWRadheader()

Method Detail

isValidFile

public boolean isValidFile(ucar.unidata.io.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 IOException

Throws:

IOException

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

swapBytes - if swap bytes

Returns:

integer

bytesToInt

public static int bytesToInt(byte[] bytes,
                             boolean swapBytes)

convert bytes into integer

Parameters:

bytes - bytes array

swapBytes - if need to swap

Returns:

integer

bytesToInt

public static int bytesToInt(byte a,
                             byte b,
                             boolean swapBytes)

Concatenate two bytes to a 32-bit int value. a is the high order byte in the resulting int representation, unless swapBytes is true, in which b is the high order byte.
