Method Detail

getEncoder

public static Base64.Encoder getEncoder()

Returns a Base64.Encoder that encodes using the Basic type base64 encoding scheme.

Returns:

A Base64 encoder.

getUrlEncoder

public static Base64.Encoder getUrlEncoder()

Returns a Base64.Encoder that encodes using the URL and Filename safe type base64 encoding scheme.

Returns:

A Base64 encoder.

getMimeEncoder

public static Base64.Encoder getMimeEncoder()

Returns a Base64.Encoder that encodes using the MIME type base64 encoding scheme.

Returns:

A Base64 encoder.

getMimeEncoder

public static Base64.Encoder getMimeEncoder(int lineLength,
                                            byte[] lineSeparator)

Returns a Base64.Encoder that encodes using the MIME type base64 encoding scheme with specified line length and line separators.

Parameters:

lineLength - the length of each output line (rounded down to nearest multiple of 4). If lineLength <= 0 the output will not be separated in lines

lineSeparator - the line separator for each output line

Returns:

A Base64 encoder.

Throws:

IllegalArgumentException - if lineSeparator includes any character of "The Base64 Alphabet" as specified in Table 1 of RFC 2045.
