<div><br></div> Wolfgang, <div><br></div><div> It seems to me that what we need to to improve the solution to address the problems you listed, but we are better now then we were before, as we support everything that was supported in 5.1 + the new use cases.</div>
<div><br></div><div> Did I miss something?</div><div><br></div><div> Edson<br><br><div class="gmail_quote">2011/4/29 Wolfgang Laun <span dir="ltr"><<a href="mailto:wolfgang.laun@gmail.com">wolfgang.laun@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">The current parser handles metadata annotations<br><br> '@' <i>Identifier</i> '(' <i>Text</i> ')'<br>
<br>so that the annotations for one entity (e.g., a rule) are available as a Map<String,Object>, where the key is given by the <i>Identifier </i>and the value of the entry is available according to<br>
<br><b>if</b> <i>Text</i> can be <i>completely</i> parsed as <i>Identifier</i> '=' <i>Expression</i> (where <i>Expression</i> is whatever the DRL parser accepts as an expression, i.e., an extended subset of Java expressions)<br>
<b>then</b><br> the value is a Map<String,String><br> <b>else<br> the </b>value is a String, with trimmed leading and trailing white space, but preserving all embedded white space<br><br>Changes compared to 5.1.1:<br>
- no Map was ever returned in 5.1.1,<br> - @m( "foo" ) in 5.1.1. returned "foo", but 5.2.0 returns "\"foo\"".<br> - @m( "foo", "bar" ) in 5.1.1. returned "foo\", \"bar", but 5.2.0 returns "\"foo\", \"bar\""<br>
- comments between "@...(" and ")" are now handled consistently but were not in 5.1.1<br><br>Possibly considered a problem for 5.2.0 or later:<br>- No check is made for duplicate "outer" map keys; entries are overwritten.<br>
- Repeated "inner" map keys produce concatenated entries, e.g. @m( k = 1, k = "a" ) returns "1a" as the value for key "k".<br>- Returning (arbitrary) expressions, unchanged, as String now may cause incompatibilitie with more sophisticated processing (if this ever should be considered).<br>
