inner class question

[Mullin]

i got compilation error:
[javac] C:\opt\SVGT\Development\src\java\hk\com\smartone\svgtx\converter\Con
verter.java:104: local variable jpegConverted is accessed from within
inner clas
s; needs to be declared final
[javac] jpegConverted =
objConvertService.convert(_objAttachment.getData(),sExtension,"JPEG",((docconv.service.ImageProfile)
(objObj
ect)));

as jpegConverted, _objAttachment, sExtension, objObject are outer
class variables and some functions of outer class may need to get and
set their values and can't assign those variables to final.

any methods to solve this?

try {
/* original code
objLog.info("before convert");
jpegConverted = objConvertService.convert(_objAttachment.getData(),sExtension,"JPEG",((docconv.service.ImageProfile)
(objObject)));
objLog.info("after convert");
*/
//
Thread th = new Thread()
{
public void run()
{
objLog.info("before convert");
jpegConverted =
objConvertService.convert(_objAttachment.getData(),sExtension,"JPEG",((docconv.service.ImageProfile)
(objObject)));
objLog.info("after convert");
}
};
th.start();
th.join(100 * 1000);
if(th.isAlive())
{
th.interrupt();
throw new Exception("Timeout");
}
//
} catch(Exception _objException) {
objLog.err(sContentName + ": Others Exception returned by
transcoder.",_objException);
convertSuccess = false;
}

If the semantics hold for your particular function, you can always do:

final <_objAttachment.getData() type> attachData=
_objAttachment.getData();
final <sExension type> attachExt = sExtension;
final docconv.service.ImageProfile attachObj = objObject;

jpegConverted =
objConvertService.convert( attachData, attachExt,"JPEG",attachObj);

If the semantics hold for your particular function, you can always do:

final <_objAttachment.getData() type> attachData=
_objAttachment.getData();
final <sExension type> attachExt = sExtension;
final docconv.service.ImageProfile attachObj = objObject;

jpegConverted =
objConvertService.convert( attachData, attachExt,"JPEG",attachObj);

or create a method in the class returning the value, called by the
inner-class.
