| How does one report errors in an IGenerator implementation? [message #1096723] |

When an IGenerator implementation detects an error in its input, how should it report it?
I suspect there's something useful to inject, but I don't see it, and (surprisingly) I can't find any examples of generators that emit errors. So I suspect that my question is invalid in some way.
Should only validators detect errors?

at the very end (I'm a novice in JAVA, ECLIPSE, ...) the following worked for me:
class UmeCif1Generator implements IGenerator {
// *** Collections to handle log and error messages
static Collection<String> logLines = new LinkedList();
static Collection<String> errLines = new LinkedList();
override void doGenerate(Resource resource, IFileSystemAccess fsa) {
var String scriptFileName = resource.getURI().lastSegment.toString();
var String outFileBase = scriptFileName.substring(0,scriptFileName.lastIndexOf("."));
fsa.generateFile( outFileBase + '.CIF',
makeTheCif(resource.contents.head as Model));
// *** output of log and error messages
if (logLines.size() > 0) fsa.generateFile( outFileBase + '.LOG',
reportLog());
if (errLines.size() > 0) fsa.generateFile( outFileBase + '.ERR',
reportErr());
}
<snip>
/* Description max 20 char long, no TAB, CRNLs */
def makeTheDescription(String description) '''
«IF description.length < 21»
-#ED «escapeStringToCif(description)»
«ELSE»
-#ED «escapeStringToCif(description).substring(0,20)»
«addLog("reduced description to 20 for " + description)»
«ENDIF»
'''
<snip>
// *** utilities to handle log and error messages
def reportLog() '''
«FOR String s : logLines»
«s»
«ENDFOR»
'''
def reportErr() '''
«FOR String s : errLines»
«s»
«ENDFOR»
'''
def addLog(String str) {
logLines.add(str)
return ""
}
def addErr(String str) {
errLines.add(str)
return ""
}
