Title: Message
Carsten,
 
I would suspect that the fastest algorithm in this case would be a set of "if" statements, e.g.,
 
for (int i = 0; i < length - 10; i++)
  if (text[i] == 'X')
  {
    i++
    if (text[i] == 'g')
    {
       ....
 
       if (text[i] == ...)
         return something;
    ... 
  }
 
This should work with practically any token that's doesn't have repeating characters.
 
In any case, I do agree with Sasha that the current token looks more like a typing mistake than anything else, and we should consider something that makes a bit more sense to developers, like an easily articulated prefix (wsia/wsrp), a pre-defined character (such as Sasha suggested) or a pre-defined tag (e.g., <consumer-link>).

Hi Sasha.

1. I think that the current intend is to return the markup as a string. In
this case it would need to be XML encoded (your first example). I also see
this preferable to requirng the markup to be XML conformant.
2. When looking for an appropriate URL rewriting marker I decided to use
plain ASCII charaters for the following reason: the fastest way to locate a
token to my knowledge is the Boyer-Moore algorithm if the token consists of
improbable characters (O(N/M), see the summary I sent out earlier). This
algorithm implies (at least any implementation I know of) that the parser
holds a table that contains the number of characters the algorithm can skip
per character to consider. If we allow UNICODE characters as the input set,
this table becomes incredibly large (too large to be useful ;-).
If I think again then maybe it makes sense to replace this map by a sparse
map implementation. Do you have experience with such an approach?


Best regards
Carsten Leue

I have a question about getMarkup.  Do we expect the markup sent back from
the method to be XML-encoded or not?  That is, let's say we want to return
the markup "Hello, <strong>World</strong>".  Does the SOAP response look
like:

<markup xsi:type="xsd:string">Hello,
&lt;strong&gt;World&lt;/strong&gt;</markup>

or like:

<markup xsi:type="markup">Hello, <strong>World</strong></markup>

As currently specified, only the former possibility is allowed, since
markup is specified with type xsd:string.  I think this is great, because
it will allow us to send non-XML conformant documents like HTML.  Further,
if we do decide that markup will be sent as an XML-encoded string, then we
could use XML elements to specify Consumer side URL rewriting, like so:

<markup xsi:type="xsd:string">Please click &lt;a href="&quot<wsia:rewriteURL
type="Action" navigationState="somestate"/>&quot;
&gt;here&lg;/a&gt;</markup>

If we don't decide to have Consumer URL writing use XML elements, though, I
think there's another solution that might be more effective than the
"wsia:QXqKYZJVUWj7G" token.  We could use Unicode characters from one of
the "private use" areas of Unicode (U+E000-U+F8FF, U+F0000-U+FFFFD, or
U+100000-U+10FFFD).  These characters are specifically designed for private
use by applications, and you can easily put them into XML with character
entities (e.g. &#xE123;).  Further, since ampersand has an escape character
in XML, you can specify when you send portlet content whether you are
sending the actual control character or text that should display as the
control character (e.g. &amp;#xE123; vs. &#xE123;).

Cheers,
Sasha.
