decodeFast

public static byte[] decodeFast(char[] chars,
                                int offset,
                                int charsLen)

已过时。

Decodes a BASE64 encoded char array that is known to be resonably well formatted. The method is about twice as fast as #decode(char[]). The preconditions are:
+ The array must have a line length of 76 chars OR no line separators at all (one line).
+ Line separator must be "\r\n", as specified in RFC 2045 + The array must not contain illegal characters within the encoded string
+ The array CAN have illegal characters at the beginning and end, those will be dealt with appropriately.

参数:

chars - The source array. Length 0 will return an empty array. null will throw an exception.

返回:

The decoded array of bytes. May be of length 0.
