RE: [MINA] Another useful shortcut

[Jose Alberto Fernandez]

Hi Trustin,   You are correct. But maybe then, some way to peek at the value (without moving the reading position) would do. Something like:     int peekInt()     short peekShort()     etc.   This will resolve most of the nasty part and allow people to check for denials as well.   How about that?   Jose Alberto   From: Trustin Lee [mailto:[EMAIL PROTECTED] Sent: 06 December 2005 01:36 To: Apache Directory Developers List Subject: Re: [MINA] Another useful shortcut   Hi Jose, 2005/12/5, Jose Alberto Fernandez <[EMAIL PROTECTED]>: Now that we have support for length prefixed strings, it would be nice to have an easy way to ask if the ByteBuffer has available (remaining) an amount specified by a byte/short/int without needing to read the value, check if there is enough, rewind and wait for more to come. Something like:             Boolean enoughAvailable(int prefixSizeLength) This may be very useful on many protocols that provide a size header in front of variable data being sent. It looks very useful, but it has a big pitfall; a possible DoS attack.  We always have to check if the length of the data doesn't exceed the predefined limit value, so providing this kind of method doesn't reduce the complexity much IMHO.
