Method Detail

values

public static Base32[] 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 (Base32 c : Base32.values())
    System.out.println(c);

Returns:

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

valueOf

public static Base32 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)

Parameters:

bytes - the bytes.

Returns:

a base 32 encoded string of the given bytes.

encode

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

Parameters:

bytes - the bytes.

Returns:

a 32 encoded byte array of the given bytes. hchar: compared to Base32.encode(byte[]) of JakartaCommons-1.5, this routine is > 20x faster on my MacAir.

decode

public static byte[] decode(String b32)

Decodes the given base 32 encoded string, skipping carriage returns, line feeds and spaces as needed. hchar: compared to Base32.decode(String) of JakartaCommons-1.5, this routine is > 11x faster on my MacAir.

Parameters:

b32 - the base 32 encoded string.

Returns:

the decoded result.

decode

public static byte[] decode(byte[] b32)

Decodes the given base 32 encoded bytes.

Parameters:

b32 - the base 32 encoded bytes.

Returns:

the decoded result.
