Enum Base64Dialect

java.lang.Object

java.lang.Enum<Base64Dialect>

io.netty.handler.codec.base64.Base64Dialect

All Implemented Interfaces:

Serializable, Comparable<Base64Dialect>

public enum Base64Dialect
extends Enum<Base64Dialect>

Enumeration of supported Base64 dialects.

The internal lookup tables in this class has been derived from Robert Harder's Public Domain Base64 Encoder/Decoder.

Enum Constant Detail

STANDARD

public static final Base64Dialect STANDARD

Standard Base64 encoding as described in the Section 3 of RFC3548.

URL_SAFE

public static final Base64Dialect URL_SAFE

Base64-like encoding that is URL-safe as described in the Section 4 of RFC3548. It is important to note that data encoded this way is not officially valid Base64, or at the very least should not be called Base64 without also specifying that is was encoded using the URL-safe dialect.

ORDERED

public static final Base64Dialect ORDERED

Special "ordered" dialect of Base64 described in RFC1940.

Method Detail

values

public static Base64Dialect[] 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 (Base64Dialect c : Base64Dialect.values())
    System.out.println(c);

Returns:

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

valueOf

public static Base64Dialect 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
