-
initDecodeMap
private static byte[] initDecodeMap()
-
guessLength
private static int guessLength(java.lang.String text)
computes the length of binary data speculatively.Our requirement is to create byte[] of the exact length to store the binary data. If we do this in a straight-forward way, it takes two passes over the data. Experiments show that this is a non-trivial overhead (35% or so is spent on the first pass in calculating the length.)
So the approach here is that we compute the length speculatively, without looking at the whole contents. The obtained speculative value is never less than the actual length of the binary data, but it may be bigger. So if the speculation goes wrong, we'll pay the cost of reallocation and buffer copying.
If the base64 text is tightly packed with no indentation nor illegal char (like what most web services produce), then the speculation of this method will be correct, so we get the performance benefit.
-
_parseBase64Binary
public static byte[] _parseBase64Binary(java.lang.String text)
- Parameters:
text
- base64Binary data is likely to be long, and decoding requires each character to be accessed twice (once for counting length, another for decoding.) A benchmark showed that takingString
is faster, presumably because JIT can inline a lot of string access (with data of 1K chars, it was twice as fast)
