builder

问题 If I have an executable that generates an output from multiple files at a time - generate_output -o a.out -f input1.txt input2.txt input3.txt Is there a way to write such a custom builder for this? What I have at the moment is - builder = Builder( action='generate_output -o $TARGET -f $SOURCE', suffix='.out', src_suffix='.txt') Then it only generates files in a sequence, which is not what I really wanted - generate_output -o input1.out -f input1.txt generate_output -o input2.out -f input2.txt

问题 I'm trying to write a class in scala that wraps a (parameterized) collection and overrides it's foreach method. What it does with the foreach method is unimportant for the purpose of this question, so lets say it just prints each element out as it's visited. So ideally, we'd be able to use the wrapper as follows: scala> val a = List(1,2,3,4,5) scala> val b = MyWrapper(a) scala> b.foreach{ x => x } 1 2 3 4 5 The key is that I want this to work with any iterable; not just a list. So my first

问题 I am reading here http://groovy.codehaus.org/modules/http-builder/doc/handlers.html "In cases where a response sends a redirect status code, this is handled internally by Apache HttpClient, which by default will simply follow the redirect by re-sending the request to the new URL. You do not need to do anything special in order to follow 302 responses." This seems to work fine when I simply use the get() or post() methods without a closure. However, when I use a closure, I seem to lose 302

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago .

问题 I was wondering when I should use the future builder. For example, if I want to make an http request and show the results in a list view, as soon as you open the view, should I have to use the future builder or just build a ListViewBuilder like: new ListView.builder( itemCount: _features.length, itemBuilder: (BuildContext context, int position) { ...stuff here... } Moreover, if I don't want to build a list view but some more complex stuff like circular charts, should I have to use the future

问题 In my application, I have to instantiate many different types of objects. Each type contains some fields and needs to be added to a containing type. How can I do this in an elegant way? My current initialization step looks something like this: public void testRequest() { //All these below used classes are generated classes from xsd schema file. CheckRequest checkRequest = new CheckRequest(); Offers offers = new Offers(); Offer offer = new Offer(); HotelOnly hotelOnly = new HotelOnly(); Hotel

问题 I am currently trying to add an assembly into report builder 3.0 to execute a method and return the result: But I always get "#Error" in the preview.

Elsewise I get a different error. 回答1: I finally fixed it. Important is to set the

问题 I am not too familiar with SQL Server Report Builder and have had prior experience with Crystal Reports, whereby you could declare a variable in the header of the report, set that variable using a sub-report, and then reference that variable in the main report, so I am having issues adapting to SQL Server Report Builder. I have a tablix that displays data. In one of the tablix columns I've embedded a sub-report. I would like to hide the tablix row based upon a value surfaced by the sub-report
