public final class LongUtil

extends Object

LongUtil Class. Class that hold only static methods to convert longs and long arrays to Strings. These Strings holds the hex or binary representation of the converted longs or long arrays. This class can't be instance, because its constructor is private.

Method Detail

toBin

public static String toBin(long in)

Converts byte to binary representation.

Parameters:

in - long that will be converted.

Returns:

String with hex representation of in.

toBin

public static String toBin(long[] in)

Converts long[] to binary representation.

Parameters:

in - long[] that will be converted.

Returns:

String with hex representation of in.

toHex

public static String toHex(long in)

Converts long to hex representation.

Parameters:

in - long that will be converted.

Returns:

String with hex representation of in.

toHex

public static String toHex(long[] in)

Converts long[] to hex representation.

Parameters:

in - long[] that will be converted.

Returns:

String with hex representation of in.

toByteArray

public static byte[] toByteArray(long input)

Converts long to a new byte[8]

Parameters:

input - that will be converted to a new byte[8] array.

Returns:

byte[8] array that holds the long in as byte array.

toByteArray

public static int toByteArray(long input,
                              byte[] output,
                              int outputOffset)
                       throws ShortBufferException

Converts long to a byte[]

Parameters:

input - that will be converted to a byte[] array.

output - the buffer for the result.

outputOffset - the offset in output where the result is stored.

Returns:

the number of bytes stored in output.

Throws:

ShortBufferException - if the given output is too small to hold the result.
