  • Using methods from the "outer" class in inner classes

    - by devoured elysium
    When defining nested classes, is it possible to access the "outer" class' methods? I know it's possible to access its attributes, but I can't seem to find a way to use its methods. addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { if (e.getClickCount() == 2 && //<-- Here I'd like to } // reference a method }); //from the class where //addMouseListener() is defined! Thanks

  • Coldfusion - taking a Serialized String and converting it to a Structure

    - by nobosh
    I have the following serialized string from a nested sortable list: ul[0][id]=main1&ul[0][children][0][id]=child2&ul[0][children][0][class]=&ul[1][id]=main3&ul[2][id]=main4&ul[3][id]=main5 I want to be able to record this in the database, and think I need a structure to do this. What's the best way to turn this into a structure, so I can sort it in the database, and easily render the list on the page in the future. Thanks,B

  • How do I compare two complex data structures?

    - by Phil H
    I have some nested datastructures, each something like: [ ('foo', [ {'a':1, 'b':2}, {'a':3.3, 'b':7} ]), ('bar', [ {'a':4, 'd':'efg', 'e':False} ]) ] I need to compare these structures, to see if there are any differences. Short of writing a function to explicitly walk the structure, is there an existing library or method of doing this kind of recursive comparison?

  • Combine Related Resources With TastyPie

    - by Aaron Ng
    How can I combine multiple Resources in TastyPie? I have 3 models I'd like to combine: users, profiles and posts. Ideally I'd like profiles nested within user. I'm not sure where to go from here. class UserResource(ModelResource): class Meta: queryset = User.objects.all() resource_name = 'user' fields = ['username','id','date_joined'] #Improper Auth authorization = Authorization() class UserProfileResource(ModelResource): class Meta: queryset = UserProfile.objects.all() resource_name = 'profile' class UserPostResource(ModelResource): user = fields.ForeignKey(UserResource,'user', full=True) class Meta: queryset = UserPost.objects.all() resource_name = 'userpost' #Improper Auth authorization = Authorization()

  • Perform selector on paren NSOperation

    - by user326943
    I extend NSOperation (call it A) which contains NSOperationQueue for other NSOperations (which is another extended class different from A, call these operations B). When operation A is running (executing B operations) how do i call a specific function/method on operation A when certain event takes place on B operations? For example every operation B that finishes it calls a function on operation A returning itself? *Nested NSOperation and NSOperationQueue(s) Thanks

  • Flex: Bottom-left align components?

    - by David Wolever
    As the title suggests, is there any way to bottom-left align components? An <HBox .../> nested in a <Canvas .../> doesn't work because the elements in the HBox are top-aligned instead of bottom aligned. For example, I'd like my components to be aligned like this: +-------------+ <-- container | components | | | V | | V +--+ | | +-+ | | | | +-+ +--+ | +-------------+

  • Centering of a div, but the normal CSS does not work

    - by Jean
    Hello, I want to center a div, but the general way is #selector{position:relative;margin:0px auto;} What exactly is wrong below #crp{top:40%; position:absolute; margin:auto;} The Div below is not nested but a standalone. The #crp is going to the extreme right. <div id="crp">...something goes here....</div> Thanks Jean

  • "ejb not bound" -- What could be the problem?

    - by Bernhard V
    Hi! When I'm running my program, I get the following error: ... nested exception is javax.naming.NameNotFoundException: ejb not bound The error occurs at the start up when Java wants to create a certain bean. The Bean is a SimpleRemoteStatelessSessionProxyFactoryBean. Could it be that I ain't got the rights to access the naming provider URL although I can ping it? When accessing the bean on my local JBoss there are no problems.

  • MySQL - Calculate the net time difference between two date-times while excluding breaks?

    - by John M
    In a MySQL query I am using the timediff/time_to_sec functions to calculate the total minutes between two date-times. For example: 2010-03-23 10:00:00 - 2010-03-23 08:00:00 = 120 minutes What I would like to do is exclude any breaks that occur during the selected time range. For example: 2010-03-23 10:00:00 - 2010-03-23 08:00:00 - (break 08:55:00 to 09:10:00) = 105 minutes Is there a good method to do this without resorting to a long list of nested IF statements?

  • Multiple column subselect in mysql 5 (5.1.42)

    - by rubber boots
    This one seems to be a simple problem, but I can't make it work in a single select or nested select. Retrieve the authors and (if any) advisers of a paper (article) into one row. I order to explain the problem, here are the two data tables (pseudo) papers (id, title, c_year) persons (id, firstname, lastname) plus a link table w/one extra attribute (pseudo): paper_person_roles( paper_id person_id act_role ENUM ('AUTHOR', 'ADVISER') ) This is basically a list of written papers (table: papers) and a list of staff and/or students (table: persons) An article my have (1,N) authors. An article may have (0,N) advisers. A person can be in 'AUTHOR' or 'ADVISER' role (but not at the same time). The application eventually puts out table rows containing the following entries: TH: || Paper_ID | Author(s) | Title | Adviser(s) | TD: || 21334 |John Doe, Jeff Tucker|Why the moon looks yellow|Brown, Rayleigh| ... My first approach was like: select/extract a full list of articles into the application, eg.SELECT q.id, q.title FROM papers AS q ORDER BY q.c_year and save the results of the query into an array (in the application). After this step, loop over the array of the returned information and retrieve authors and advisers (if any), via prepared statement (? is the paper's id) from the link table like:APPLICATION_LOOP(paper_ids in array) SELECT p.lastname, p.firstname, r.act_role FROM persons AS p, paper_person_roles AS r WHERE p.id=r.person_id AND r.paper_id = ? # The application does further processing from here (pseudo): foreach record from resulting records if record.act_role eq 'AUTHOR' then join to author_column if record.act_role eq 'ADVISER' then join to avdiser_column end print id, author_column, title, adviser_column APPLICATION_LOOP This works so far and gives the desired output. Would it make sense to put the computation back into the DB? I'm not very proficient in nontrivial SQL and can't find a solution with a single (combined or nested) select call. I tried sth. like SELECT q.title (CONCAT_WS(' ', (SELECT p.firstname, p.lastname AS aunames FROM persons AS p, paper_person_roles AS r WHERE q.id=r.paper_id AND r.act_role='AUTHOR') ) ) AS aulist FROM papers AS q, persons AS p, paper_person_roles AS r in several variations, but no luck ... Maybe there is some chance? Thanks in advance r.b.

  • XSLT: Transform XML files tree

    I have the following file structure (XML files 'index.xml' in nested folders): index.xml foo/index.xml foo/sub/index.xml foo/.../index.xml bar/.../index.xml Now I have to transform each of this XML files with a given XSL stylesheet. The result should be the same folder structure (overwriting would be OK). What would be your approach to achieve this? My system: OS X 10.6, Saxon XSLT processor

  • RoR - Associations into practise - forms (View)

    - by NicoJuicy
    I'm learning Ruby on Rails. I'm using some associations (has_many :through, ...) But i'm having some problems with it when i'm combining my views. How exactly do i combine these nested forms? Can i do this with partial forms and where do i have to write extra code for this? I have seen examples only use the "view" and others also edit the controller.... An example would be very nice :-)

  • format - Help with printing a table

    - by Michael Kohl
    This question will probably end in a facepalm, but I've tried for a while and am still stuck despite reading through the hyperspec. Basically what I want to do is something like (format t "~{|~{ ~5d~}|~%~}" '((1 23 2 312) (23 456 1 7890))) but instead of hard-coding the 5 it should be calculated from the list (length of longest element from any nested list + 1) to give something like | 1 23 2 312| | 23 456 1 7890| Maybe I'm thinking way too complicated here and there is an easier way to do what I want, but I think I ran myself into a mental corner that I can't get out of.

  • PCRE (recursive) pattern that matches a string containing a correctly parenthesized substring. Why d

    - by Anton N. Petrov
    Well, there are other ways (hmmm... or rather working ways) to do it, but the question is why does this one fail? / \A # start of the string ( # group 1 (?: # group 2 [^()]* # something other than parentheses (greedy) | # or \( (?1) \) # parenthesized group 1 ) # -group 2 + # at least once (greedy) ) # -group 1 \Z # end of the string /x Fails to match a string with nested parentheses: "(())"

  • SQL: How to order values inside group by

Thank you!

  • Changing default REST routes in Rails 3

    - by Vincent
    I need to add one parameter to the default REST route for the show action for SEO purposes: resources :neighborhoods, :only => [:index, :show] neighborhood_url(neighborhood) # => /neighborhoods/lower-east-side I want something like the following: neighborhood_url(city, neighborhood) # => /neighborhoods/manhattan/lower-east-side What would be the easiest way to do this without using nested routes and without breaking Rails REST conventions?
