Re: Re: [OGNL] Mask operators
@Daniel: Of course I do not use OGNL for only selecting an entry from a simple Map. My application uses OGNL for navigating thru a complex (unknown) graph and doing calculations based on the values inside the graph. I just gave a simple example to explain my needs... @Chris: I have tried this already. If I write Ognl.getValue(\a-b\, m), OGNL interprets 'a-b' as a String and returns it instead of trying to get the value for the 'a-b'-key from m.

Re: [Collections] Circular Buffer
what exactly are you trying to do? Perhaps a circular buffer isn't what you're looking for. On Mar 6, 2012 1:48 AM, manoj mokashi manojmoka...@gmail.com wrote: The existing CircularFifoBuffer would suffice if it had an efficient get(index) method, which gets an element with the specified index from the end. btw, the code i posted originally refers mistakenly to another Int Buffer class and is not correct. Also the IllegalArgumentCheck and the fill constructor needs changing. Sorry about that. - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
Antwort: Re: Re: [OGNL] Mask operators
Thanks Maurizio, this works perfectly! If somebody else needs this: Use parentheses if you need this inside a longer path (data graph), i.e. Ognl.getValue( keyInOuterMap.(['a-b']).keyInNestedMap,m ) maurizio.cucchi...@gmail.com schrieb am 06.03.2012 10:54:36: Von: Maurizio Cucchiara mcucchi...@apache.org An: Commons Users List user@commons.apache.org Datum: 06.03.2012 11:36 Betreff: Re: Re: [OGNL] Mask operators Gesendet von: maurizio.cucchi...@gmail.com This should be work: Ognl.getValue( ['a-b'],m ) Twitter :http://www.twitter.com/m_cucchiara G+ :https://plus.google.com/107903711540963855921 Linkedin:http://www.linkedin.com/in/mauriziocucchiara Maurizio Cucchiara On 6 March 2012 09:10, stephan.dco...@arz.at wrote: @Daniel: Of course I do not use OGNL for only selecting an entry from a simple Map.

[sanselan] Writing EXIF data to JPEG
Hi Sanselan. I have a hard time finding out how to use Sanselan. Suppose I have some JPEG picture which I want to add some attributes to. If for example I want to add some user comment or date I try this: TiffOutputSet outputSet = new TiffOutputSet(); TiffOutputField dateTaken = TiffOutputField.create(TiffConstants.EXIF_TAG_CREATE_DATE, outputSet.byteOrder, 2003:03:29 17:47:50); TiffOutputField comment = TiffOutputField.create(TiffConstants.EXIF_TAG_IMAGE_DESCRIPTION, outputSet.byteOrder, This is a test!); However, both of these fails on unexpected data type. If I am not supposed to give a String, then what I am supposed to supply? I hope you can help with these, probably noobish questions. /Kasper - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
