Method Detail

serialize

public static byte[] serialize(java.lang.Object source)

Attempts to serialize the given object to a byte array.

Parameters:

source - the object to serialize.

Returns:

the serialized byte array.

deserialize

public static java.lang.Object deserialize(byte[] source)

Attempts to deserialize the given byte array. It is up to the developer to know what type to expect from the deserialization.

Parameters:

source - the byte array to deserialize.

Returns:

the deserialized object.

base64Encode

public static java.lang.String base64Encode(byte[] input)

Encodes the given byte array to a Base64 string.

Parameters:

input - The byte array to encode.

Returns:

the encoded string.

base64Decode

public static byte[] base64Decode(java.lang.String input)

Decodes the given Base64-encoded string.

Parameters:

input - The Base64-encoded string.

Returns:

the decoded byte array.

itoa

public static java.lang.String itoa(int i,
                                    int base)

Converts the given number to its string representation.

The hexadecimal representation uses the 2's complement to represent negative numbers. Always the smallest possible multiple of 4-bits is used to represent the number. E.g., for -1 the hex representation is 0xf (1111). For -8 it's 0x8 (1000). If we move out of the range [-8, 7], four more bits are added, such that -9 is 0xf7 (1111 0111).

Parameters:

i - The number

base - The base to use for the string representation. Can be decimal (10) or hexadecimal (16).

Returns:

the number as a string.

atoi

public static int atoi(java.lang.String s,
                       int base)

Converts the given number string into an integer.

Parameters:

s - The number string.

base - The base to use for interpreting the string. Can be decimal (10) or hexadecimal (16).

Returns:

the number.
