                              int offset)

Deprecated.

Returns the short resulting from swapping 2 bytes at a specified offset in a byte array.

Parameters:

b - the byte array

offset - the offset of the first byte

Returns:

the short represented by the bytes b[offset+1], b[offset]

swapInt

public static int swapInt(byte[] b,
                          int offset)

Deprecated.

Returns the int resulting from reversing 4 bytes at a specified offset in a byte array.

Parameters:

b - the byte array

offset - the offset of the first byte

Returns:

the int represented by the bytes b[offset+3], b[offset+2], ..., b[offset]

swapLong

public static long swapLong(byte[] b,
                            int offset)

Deprecated.

Returns the long resulting from reversing 8 bytes at a specified offset in a byte array.

Parameters:

b - the byte array

offset - the offset of the first byte

Returns:

the long represented by the bytes b[offset+7], b[offset+6], ..., b[offset]

swapFloat
