Hi. I try to find a way to disable the PatternLock screen temporary. I don't want the lock to be disabled completely, but the user should not need to re-enter his pattern all the time. My idea is to write a service which disables the pattern after some user activity and re-enables it after a while. (and even more) There are apps on th...
Hi there, I'm developing a price calculation engine. I've looked all over and there's nothing that really fits what we need. However, I'm now looking how to implement specific prices and/or discounts. I don't want to introduce a rule based engine to my end-users, because they won't get it. For example, when you order an ItemX the price ...
My domain entities are lined up like a tree: Root - Child 1 -- Child 1.1 -- Child 1.2 - Child 2 -- Child 2.1 -- Child 2.2 We ended up with 2 (rather strong) opinions on how a repository should be designed around these domain objects: Opinion 1: I need 2 repositories Child1Repository & Child2Repository which gets managed by a RootFac...
Hi, I'm a beginner programmer, and am wondering how to work around this issue. The problem I am trying to solve is keeping a tally of static method calls in my program using a java.util.Observer. Clearly, my original post must have just confused people so I'll leave it more open-ended: can anyone suggest a way to keep a static method ...

In Perl, you can get a list of files that match a pattern: my @list = <*.txt>; print "@list"; Now, I'd like to pass the pattern as a variable (because it's passed into a function). But that doesn't work: sub ProcessFiles { my ($pattern) = @_; my @list = <$pattern>; print "@list"; } readline() on unopened filehandle at ... ...

If you look at the example for catches: f = expr `catches` [Handler (\ (ex :: ArithException) -> handleArith ex), Handler (\ (ex :: IOException) -> handleIO ex)] It looks like catches has defined a custom mechanism to match on patterns (the two exception types). Am I mistaken, or can this be generalized to ...
I'm trying to use a regular expression to find all substrings that start with an equals sign (=) and ends with a semicolon (;) with any number of characters in between. It should be something like this =*; For some reason, the equals is not registering. Is there some sort of escape character that will make the regex notice my equals sig...
I'm looking for a shape recognition tool for Java. In particular, I'd like to find a Java library that given an image file (in jpeg, bmp, gif or any common image file format) gives me information about the regular shapes (rectangles, lines, ...) found in the picture and their coordinates. In previous questions on this topic I've seen r...

Hi Guys, After developing in CodeIgniter for awhile, I find it difficult to make decision as to when do i create a custom library and when do i create a custom helper. I do understand that both allows you to have business logic in it and is reusable across the framework(calling from different controller etc.) But I strongly believe th...

Hi. I was wondering if anybody knows how I can use JAXB together with the Builder Pattern? The builder pattern wants you to set the constructor as private, and JAXB says "1 counts of IllegalAnnotationExceptions myClass does not have a no-arg default constructor" Is there somehow I can tell JAXB that I don't want no-arg default constru...
Does the Factory Method pattern (not to be confused with the Factory or Abstract Factory patterns) violate the Open/Closed principle? Update: To clarify, I'm referring to the scenario where a concrete class has static factory methods on it. For example (this is from the Wikipedia page on FMP): class Complex { public static Complex...
Hi, I'm toying with an app idea for the iPhone but I don't know where to start or even what to look for in google :) I'd like to visualize math patterns on the iPhone, similar to this http://itunes.apple.com/us/app/patterns-lite/id304565312?mt=8 ... If someone could point me into the right direction then that would be fantastic. Original...
I'm currently working on a small utility program that only requires a command line interface, and I started wondering if Java provided any standard way of creating the CLI, in a similar way that Swing and the likes exist for GUIs. I'm not really interested in command line parameters and parsing of them, but rather the command based inter...
Hey all - So I'm working to improve an existing implementation. I have a number of polymorphic classes that are all composed into a higher level container class. The problem I'm dealing with at the moment is that the higher level container class, well, sucks. It looks something like this, which I really don't have a problem with (as th...
What is the pattern (best practice) for such problem -- modifying elements (values) in collection? Conditions: size of the collection is not changed (no element is deleted or added) modification is in-place In C++ it was easy and nice, I just iterated trough a collection and changed the elements. But in C# iterating (using enumerato...
