, but not escape
. For example
in this encoding, é (in Unicode U+00E9
or in UTF-8
0xC3 0xA9
) is encoded as %C3%A9
or %c3%a9
.
This is essentially equivalent to calling
URLDecoder
.URLDecoder.decode(String, String)
except that it's over 2x faster and generates less garbage for the GC.
Actually this function doesn't allocate any memory if there's nothing
to decode, the argument itself is returned.s

- The charset to use to decode the string (should really
be Charsets.UTF_8
.s
if there's nothing to decode.
If the string to decode is null
, returns an empty string.IllegalArgumentException
- if the string contains a malformed
escape sequence.Copyright © 2009–2015. All rights reserved.
