|
A very fast and memory efficient class to encode and decode to and from BASE64 in full accordance
|
|
with RFC 2045.<br><br>
|
|
On Windows XP sp1 with 1.4.2_04 and later ;), this encoder and decoder is about 10 times faster
|
|
on small arrays (10 - 1000 bytes) and 2-3 times as fast on larger arrays (10000 - 1000000 bytes)
|
|
compared to <code>sun.misc.Encoder()/Decoder()</code>.<br><br>
|
|
|
|
On byte arrays the encoder is about 20% faster than Jakarta Commons Base64 Codec for encode and
|
|
about 50% faster for decoding large arrays. This implementation is about twice as fast on very small
|
|
arrays (< 30 bytes). If source/destination is a <code>String</code> this
|
|
version is about three times as fast due to the fact that the Commons Codec result has to be recoded
|
|
to a <code>String</code> from <code>byte[]</code>, which is very expensive.<br><br>
|
|
|
|
This encode/decode algorithm doesn't create any temporary arrays as many other codecs do, it only
|
|
allocates the resulting array. This produces less garbage and it is possible to handle arrays twice
|
|
as large as algorithms that create a temporary array. (E.g. Jakarta Commons Codec). It is unknown
|
|
whether Sun's <code>sun.misc.Encoder()/Decoder()</code> produce temporary arrays but since performance
|
|
is quite low it probably does.<br><br>
|
|
|
|
The encoder produces the same output as the Sun one except that the Sun's encoder appends
|
|
a trailing line separator if the last character isn't a pad. Unclear why but it only adds to the
|
|
length and is probably a side effect. Both are in conformance with RFC 2045 though.<br>
|
|
Commons codec seem to always att a trailing line separator.<br><br>
|
|
|
|
<b>Note!</b>
|
|
The encode/decode method pairs (types) come in three versions with the <b>exact</b> same algorithm and
|
|
thus a lot of code redundancy. This is to not create any temporary arrays for transcoding to/from different
|
|
format types. The methods not used can simply be commented out.<br><br>
|
|
|
|
There is also a "fast" version of all decode methods that works the same way as the normal ones, but
|
|
har a few demands on the decoded input. Normally though, these fast verions should be used if the source if
|
|
the input is known and it hasn't bee tampered with.<br><br>
|
