  • Is it possible to set a default behaviour for custom (non-native) methods/functions in Java?

    - by Tom
    Is it possible to set a default behaviour for custom (non-native) methods/functions in Java? For example, I would like to change the default "Function" to do a System.out.println("message") whenever called. So, when a custom method/function is being created: public String testMethod() { //custom code } it should execute the newly added default behaviour (in this case the system output), before the custom code is run. Even if this would be a bad excercise, is it possible? Maybe by extending the function class or something?

  • SAX parser does not resolve filename

    - by phantom-99w
    Another day, another strange error with SAX, Java, and friends. I need to iterate over a list of File objects and pass them to a SAX parser. However, the parser fails because of an IOException. However, the various File object methods confirm that the file does indeed exist. The output which I get: 11:53:57.838 [MainThread] DEBUG DefaultReactionFinder - C:\project\trunk\application\config\reactions\TestReactions.xml 11:53:57.841 [MainThread] ERROR DefaultReactionFinder - C:\project\trunk\application\config\reactions\null (The system cannot find the file specified) So the problem is obviously that null in the second line. I've tried nearly all variations of passing the file as a parameter to the parser, including as a String (both from getAbsolutePath() and entered by hand), as a URI and, even more weirdly, as a FileInputStream (for this I get the same error, except that the entire relative path gets reported as null, so C:\project\trunk\null). All that I can think of is that the SAXParserFactory is incorrectly configured. I have no idea what is wrong, though. Here is the code concerned: SAXParserFactory factory = SAXParserFactory.newInstance(); factory.setValidating(true); try { parser = factory.newSAXParser(); } catch (ParserConfigurationException e) { throw new InstantiationException("Error configuring an XML parser. Given error message: \"" + e.getMessage() + "\"."); } catch (SAXException e) { throw new InstantiationException("Error creating a SAX parser. Given error message: \"" + e.getMessage() + "\"."); } ... for (File f : fileLister.getFileList()) { logger.debug(f.getAbsolutePath()); try { parser.parse(f, new ReactionHandler(input)); //FileInputStream fs = new FileInputStream(f); //parser.parse(fs, new ReactionHandler(input)); //fs.close(); } catch (IOException e) { logger.error(e.getMessage()); throw new ReactionNotFoundException("An error occurred processing file \"" + f + "\"."); } ... } I have made no special provisions to provide a custom SAX parser implementation: I use the system default. Any help would be greatly appreciated!

  • replace NA in an R vector with adjacent values

    - by pssguy
    I have a dataframe which has merged player and team data for soccer seasons So for a particular player in a specific season I have data like df <- data.frame(team=c(NA,"CRP",NA,"CRP","CRP",NA), player=c(NA,"Ed",NA,"Ed","Ed",NA), playerGame= c(NA,1,NA,2,3,NA), teamGame =c(1,2,3,4,5,6)) Where the NA's indicate that the player did not appear in that specific team game How would I most efficiently replace the team and player NA's with "CRP" and "Ed" respectively and have a plGame output of, in this instance, 0,1,1,2,3,3

  • How do I use a string as a keyword argument?

    - by Issac Kelly
    Specifically, I'm trying to use a string to arbitrairly filter the ORM. I've tried exec and eval solutions, but I'm running into walls. The code below doesn't work, but it's the best way I know how to explain where I'm trying to go from gblocks.models import Image f = 'image__endswith="jpg"' # Would be scripted in another area, but passed as text <user input> d = Image.objects.filter(f) #for the non-django pythonistas: d = Image.objects.filter(image__endswith="jpg") # would be the non-dynamic equivalent.

  • How to properly clean up JDBC resources in Java?

    - by user523086
    What is considered best practices when cleaning up JDBC resources and why? I kept the example short, thus just the cleaning up of the ResultSet. finally { if(rs != null) try{ rs.close(); } catch(SQLException ignored) {} } versus finally { try{ rs.close(); } catch(Exception ignored) {} } Personally I favour the second option since it is a bit shorter. Any input on this is much appreciated.

  • How can I check the MIME type of an uploaded file using Perl CGI?

    - by FOOM
    I'm trying to get the MIME type of an <input type="file" /> element using Perl, but without actually examining the contents of the file itself, In other words, just using the HTTP headers. I have only been able to get the "multipart/form-type" Content-Type value, but my understanding is that each element will get its own MIME Type? How can I see the sub-MIME types using Perl?

  • python how to find the median of a list

    I'm trying to write a function named median that takes a list as an input and returns the median value of the list. I'm working with Python 2.7.2 The list can be of any size and the numbers are not guaranteed to be in any particular order. If the list contains an even number of elements, the function should return the average of the middle two. This is the code I'm starting with: def median(list): print(median([7,12,3,1,6,9]))

  • Images inside of UILabel

    - by enby
    hello everyone! I'm trying to find the best way to display images inside of UILabels (in fact, I wouldn't mind switching to something other than UILabel if it supports images with no hassle) The scenario is: I have a table view with hundreds of cells and UILabel being the main component of each cell The text I assign to each cell contains sequences of characters that need to be parsed out and represented as an image In simpler words, imagine a TableView of an instant messenger that parses replaces all ":)", ":(", ":D" etc with corresponding smiley images Any input would be greatly appreciated!
