public static String decodeComponent(String s)
This is equivalent to calling decodeComponent(String, Charset)
with the UTF-8 charset (recommended to comply with RFC 3986, Section 2).
s
- The string to decode (can be empty).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.public static String decodeComponent(String s, Charset charset)
The string is expected to be encoded as per RFC 3986, Section 2.
This is the encoding used by JavaScript functions encodeURI
and encodeURIComponent
, 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
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.URLDecoder.decode
(s, charset.name())
s
- The string to decode (can be empty).charset
- The charset to use to decode the string (should really
be CharsetUtil.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 © 2008-2013 The Netty Project. All Rights Reserved.
