merge rows csv by id ruby

阅读更多关于 merge rows csv by id ruby

问题 I have a .csv file that, for simplicity, is two fields: ID and comments. The rows of id's are duplicated where each comment field had met max char from whatever table it was generated from and another row was necessary. I now need to merge associative comments together thus creating one row for each unique ID, using Ruby. To illustrate, I'm trying in Ruby, to make this: ID | COMMENT 1 | fragment 1 1 | fragment 2 2 | fragment 1 3 | fragment 1 3 | fragment 2 3 | fragment 3 into this: ID |

what is the purpose of @Nonbinding annotation in a Qualifier supposed to be in Java EE7?

问题 I am reading through the CDI injections in JavaEE 7 particularly using @Qualifier and @Produces to inject a custom Data type into a bean. I have the following code taken from JBoss documentation towards ends of the page. @Qualifier @Retention(RUNTIME) @Target({TYPE, METHOD, FIELD, PARAMETER}) public @interface HttpParam { @Nonbinding public String value(); } import javax.enterprise.inject.Produces; import javax.enterprise.inject.spi.InjectionPoint; class HttpParams { @Produces @HttpParam("")

Ruby inject until sum exceeds a set value and return the index where this occurs

阅读更多关于 Ruby inject until sum exceeds a set value and return the index where this occurs

问题 With the following array and value: v = 50 a = [10, 20, 25, 10, 15] I want to iterate through the array adding up the values until the sum of these values exceeds the variable v. And then I want to be able to return the index in the array where that occurred. so... 10 + 20 + 25 = 55 (which is the first point which the sum is greater that 'v') so index = 2 Thanks for your help 回答1: For the sum: a.inject do |sum,n| break sum if sum > v sum + n end For the index, idea is the same - you use the

@Dependent @javax.ejb.Singleton versus @ApplicationScoped @javax.ejb.Singleton?

阅读更多关于 @Dependent @javax.ejb.Singleton versus @ApplicationScoped @javax.ejb.Singleton?

In essence, what is the difference between these two classes: @ApplicationScoped @Singleton class A {} @Dependent @Singleton class B {} Contextual EJB instances I prefer not to use @Inject when looking for EJB:s, unless the EJB is a @Stateful and I want the CDI container to manage the stateful's life-cycle which could be very convenient. Otherwise, using @Inject to retrieve a contextual EJB instance is a bit dangerous. For example, a @Remote client-view cannot be retrieved using CDI unless we also write a producer . Furthermore, class A and class B can not declare any other scope than what

How do i send keys using a global keyboard hook?

阅读更多关于 How do i send keys using a global keyboard hook?

问题 I'm trying to send keys to an application which does not respond to any of the API's that I have so far used (SendInput(), PostMessage(), SendMessage() and others). However, i tested Windows' On-Screen Keyboard Utility and pressed the keys i needed and the application received these keys easily. If i understand correctly the keyboard utility uses global keyboard hooks to send the keys, so I'm interested i how i could do so as well. I have tried finding examples of how this can be done on

CDI - Injecting objects dynamically at runtime

阅读更多关于 CDI - Injecting objects dynamically at runtime

How do I inject objects at runtime? For example, if I want to inject DerviedOne, DerivedTwo objects at runtime into the Test class in the following example, how do I do that? I found a few examples in Spring, but I'm not using Spring. This is a Dynamic Web Project with CDI using Java EE 6. public abstract class Base { public Base(String initiator) { this.initiator = initiator; } public abstract void process(); public void baseProcess() { System.out.println("base process"); process(); } public String getInitiator() { return initiator; } private String initiator; } public class BaseUtil { public

Java EE 6 @Inject lazy? [duplicate]

阅读更多关于 Java EE 6 @Inject lazy? [duplicate]

问题 This question already has answers here : How to make a CDI bean lazily initialized? (3 answers) Closed 6 years ago . I am doing some refactoring and reviewing of the application that we are currently developing. While doing this I found that more beans are injected and I think making they loading in an lazy manner would be better suited for their purpose. I am using Java EE 6 and tend to use more CDI than EJB injection. So the question is whether it is possible to inject the beans lazily and
