Class Base64Encoder

java.lang.Object
  com.mucommander.io.base64.Base64Encoder

public abstract class Base64Encoder
extends java.lang.Object

Base64Encoder provides methods to ease the encoding of strings and byte arrays in base64. The Base64OutputStream class is used under the hood to perform the actual base64 encoding.

Method Detail

encode

public static java.lang.String encode(byte[] b)

Base64-encodes the given byte array and returns the result. The specified encoding is used for tranforming the string into bytes.

Parameters:

b - the String to base64-encode

Returns:

the base64-encoded String

encode

public static java.lang.String encode(byte[] b,
                                      int off,
                                      int len)

Base64-encodes the given byte array, from off to len, and returns the result. The specified encoding is used for tranforming the string into bytes.

Parameters:

b - the String to base64-encode

off - position to the first byte in the array to be encoded

len - number of bytes in the array to encode

Returns:

the base64-encoded String

encode

public static java.lang.String encode(java.lang.String s)

Shorthand for encode(String, String) invoked with UTF-8 encoding.

Parameters:

s - the String to base64-encode

Returns:

the base64-encoded String

encode

public static java.lang.String encode(java.lang.String s,
                                      java.lang.String encoding)
                               throws java.io.UnsupportedEncodingException

Base64-encodes the given String and returns result. The specified encoding is used for tranforming the string into bytes.

Parameters:

s - the String to base64-encode

encoding - the character encoding to use for transforming the string into bytes

Returns:

the base64-encoded String

Throws:

java.io.UnsupportedEncodingException - if the specified encoding is not supported by the Java runtime
