Method Detail

values

public static Base64[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Base64 c : Base64.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Base64 valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

encodeAsString

public static String encodeAsString(byte... bytes)

Returns a base 64 encoded string of the given bytes.

Parameters:

bytes - the bytes

Returns:

the string

encode

public static byte[] encode(byte[] bytes)

Returns a 64 encoded byte array of the given bytes.

Parameters:

bytes - source

Returns:

a 64 encoded byte array of the given bytes

decode

public static byte[] decode(String b64)

Decodes the given base 64 encoded string, skipping carriage returns, line feeds and spaces as needed.

Parameters:

b64 - the b 64

Returns:

the byte [ ]

decode

public static byte[] decode(byte[] b64)

Decodes the given base 64 encoded bytes.

Parameters:

b64 - the b 64

Returns:

the byte [ ]
