问题 I am currently using Builder to make a custom XML export. However when the user clicks the button I want the .xml to download instead of rendering. I have tried using send_data instead of render but that seems to be overridden by builder. Also using ActiveAdmin (hence the member_action ) In my controller: member_action :show do @listing = Listing.find(params[:id]) respond_to do |format| format.html format.xml end end Links to show.xml.builder xml.instruct! xml.XMLopener { |b| b..... ...... ..

问题 I need to build a huge XML file, about 1-50 MB. I thought that using builder would be effective enough and, well it is, somewhat. The problem is, after the program reaches its last line it doesn't end immediately, but Ruby is still doing something for several seconds, maybe garbage collection? After that the program finally ends. To give a real example, I am measured the time of building an XML file. It outputs 55 seconds (there is a database behind so it takes long) when the XML was built,

问题 I need to implement Builder pattern without static nested classes. What is the best approach for doing it if I have inheritance? Let's imagine I have the following classes. public class Car { private String brand; private String speed; //getters an setters } public class PassengerCar extends Car{ private String capacity; //getters an setters } public class Truck extends Car{ private String length; //getters an setters } Is it better to create one Builder class that will responsible for

问题 Let's say I have an abstract class (BaseThing). It has one required parameter ("base required") and one optional parameter ("base optional"). I have a concrete class that extends it (Thing). It also has one required parameter ("required") and one optional parameter ("optional"). So something like: public abstract class BaseThing { public static final String DEFAULT_BASE_OPTIONAL = "Default Base Optional"; private final String baseRequired; private String baseOptional = DEFAULT_BASE_OPTIONAL;

问题 I am learning to use Laravel 5, but I am at the query builder phase, and after looking at the first code snippets I think it is really useless when somebody has basic SQL knowledge. Example: $users = DB::table('users') ->select(DB::raw('count(*) as user_count, status')) ->where('status', '<>', 1) ->groupBy('status') ->get(); What is the purpose of learning query builder syntax if the programmer actually has at least basic knowledge about the SQL language? Moreover, moving advanced queries

问题 I'm aware there've been similar questions. I haven't seen an answer to my question though. I'll present what I want with some simplified code. Say I have a complex object, some of its values are generic: public static class SomeObject<T, S> { public int number; public T singleGeneric; public List<S> listGeneric; public SomeObject(int number, T singleGeneric, List<S> listGeneric) { this.number = number; this.singleGeneric = singleGeneric; this.listGeneric = listGeneric; } } I'd like to

问题 What is the memory and performance usage compared to creating a object with only a constructor? The usage here is in creating a Set<Object> or List<Object> that may contain million plus entries and I am concerned with the overhead of using Bloch's Builder Pattern. I have used it in the past, but never in this large of a scope. Reference: Item 2: Consider a builder when faced with many constructor parameters, reprinted in Creating and Destroying Java Objects: Part 1, excerpted from Effective

问题 sample code: def ant = new AntBuilder() ant.'antlib:org.jacoco.ant:agent'( enabled: enabled, property: 'agentvmparam') When that "enabled" parameter is null, I'd like it to be not present in the ant task conversion, not merely "empty". "empty" gets evaluated to "true" http://ant.apache.org/manual/develop.html#set-magic which isn't what I want. xml builder example: def xml = new MarkupBuilder() xml.omitNullAttributes = true xml.root( requiredAttribute:'required', optionalAttribute:
