Class EndianConverter

java.lang.Object
  net.sf.japi.util.EndianConverter

public class EndianConverter
extends Object

Class to convert data from little endian to big endian and vice versa. Since the conversion is symmetric, there are no special conversion methods, just generic ones, e.g. the same method is used to convert a little endian integer to a big endian integer and vice versa.

Method Detail

swapEndianess

public static final double swapEndianess(double d)

Convert a double. This method changes byte order from 1, 2, 3, 4, 5, 6, 7, 8 to 8, 7, 6, 5, 4, 3, 2, 1.

Parameters:

d - double to convert

Returns:

converted double

swapEndianess

public static final float swapEndianess(float f)

Convert a float. This method changes byte order from 1, 2, 3, 4 to 4, 3, 2, 1.

Parameters:

f - float to convert

Returns:

converted float

swapEndianess

public static final long swapEndianess(long l)

Convert a long. This method changes byte order from 1, 2, 3, 4, 5, 6, 7, 8 to 8, 7, 6, 5, 4, 3, 2, 1.

Parameters:

l - long to convert

Returns:

converted long

swapEndianess

public static final int swapEndianess(int i)

Parameters:

i - int to convert

Returns:

converted int

swapEndianess

public static final char swapEndianess(char c)

Convert a char. This method swaps low and high byte.

Parameters:

c - char to convert

Returns:

converted char

swapEndianess

public static final short swapEndianess(short s)

Convert a short. This method swaps low and high byte.

Parameters:

s - short to convert

Returns:

converted short

swapEndianess

public static final byte swapEndianess(byte b)

Convert a byte. This method does nothing and exists for convenience only.

Parameters:

b - byte to convert

Returns:

converted byte (same as b)

swapEndianess

public static final boolean swapEndianess(boolean b)

Convert a boolean. This method does nothing and exists for convenience only.

Parameters:

b - boolean to convert

Returns:

converted boolean (same as b)
