[CLIPS][JAVA]如何从控制台获取字符串并插入输入

Question

I'm developing a little expert-system with Clips and Java using Clipsjni.我正在使用 Clipsjni 使用 Clips 和 Java 开发一个小专家系统。 I've encountered a problem and I can't find a solution online, so I'm asking to You.我遇到了一个问题，我在网上找不到解决方案，所以我问你。 I want to put the output of the function clips.run() in a JLable becouse I need to use java swing and I want to put the input from a TextBox and not from the console.我想将函数 clips.run() 的输出放在 JLable 中，因为我需要使用 java swing 并且我想从 TextBox 而不是来自控制台的输入。

Here's an example of a program that runs normally with the console:下面是一个与控制台一起正常运行的程序示例：

import net.sf.clipsrules.jni.Environment;

public class Example {

    public static Environment clips = new Environment();
    public static void main (String[] args)
    {
        clips.load("hello.clp");
        clips.reset();
        clips.run();
    }
}

And this is my Hello.clp:这是我的 Hello.clp：

(defrule question
=>
(printout t "How old are you?" crlf)
(assert (age (read)))
)

this is what i get from the system console:这是我从系统控制台得到的：

How old are you?你几岁？ 12 12

So I want " How old are you? " to be saved in a String type and put the "12" from a string.所以我希望“你多大了？”以字符串类型保存并从字符串中输入“12”。 How can I solve this?我该如何解决这个问题？ Hoping for your help!希望得到您的帮助！

Rather than placing strings that will be seen by the user directly within the rules, use facts instead.不要将用户直接看到的字符串放置在规则中，而是使用事实。

CLIPS> 
(deftemplate question
  (slot id)
  (slot text))
CLIPS>   
(deftemplate value
  (slot id)
  (slot value))
CLIPS>   
(defrule ask-question
  (question (id ?id)
            (text ?text))
  =>
  (printout t ?text " ")
  (assert (value (id ?id) (value (read)))))
CLIPS> (assert (question (id age) (text "How old are you?")))
<Fact-1>
CLIPS> (run)
How old are you? 44
CLIPS> (facts)
f-0     (initial-fact)
f-1     (question (id age) (text "How old are you?"))
f-2     (value (id age) (value 44))
For a total of 3 facts.
CLIPS> (reset)
CLIPS> (assert (question (id age) (text "Wie alt sind Sie?")))
<Fact-1>
CLIPS> (run)
Wie alt sind Sie? 44
CLIPS> (facts)
f-0     (initial-fact)
f-1     (question (id age) (text "Wie alt sind Sie?"))
f-2     (value (id age) (value 44))
For a total of 3 facts.

In CLIPSJNI, you can use the assertString function to assert facts into CLIPS from your Swing application.在 CLIPSJNI 中，您可以使用 assertString 函数从 Swing 应用程序将事实断言到 CLIPS。 For example, here's a snippet from the WineDemo example included with CLIPSJNI:例如，这里是 CLIPSJNI 中包含的 WineDemo 示例中的一个片段：

clips.assertString("(attribute (name sauce) (value unknown))");

Use the fact query functions to extract information from facts.使用事实查询函数从事实中提取信息。 For example, here's a snippet from the SudokoDemo example included with CLIPSJNI:例如，这里是 CLIPSJNI 中包含的 SudokoDemo 示例的片段：

 String evalStr;
 String messageStr = "<html><p style=\"font-size:95%\">";

 evalStr = "(find-all-facts ((?f technique)) TRUE)";

 MultifieldValue mv = (MultifieldValue) clips.eval(evalStr);
 int tNum = mv.size();

 for (int i = 1; i <= tNum; i++)
   {
    evalStr = "(find-fact ((?f technique-employed)) " +
                   "(eq ?f:priority " + i + "))";

    mv = (MultifieldValue) clips.eval(evalStr);
    if (mv.size() == 0) continue;

    FactAddressValue fv = (FactAddressValue) mv.get(0);

    messageStr = messageStr + ((NumberValue) fv.getFactSlot("priority")).intValue() + ". " +
                              ((LexemeValue) fv.getFactSlot("reason")).lexemeValue() + "<br>";
   }
JOptionPane.showMessageDialog(jfrm,messageStr,sudokuResources.getString("SolutionTechniques"),JOptionPane.PLAIN_MESSAGE);

Basically you use the eval function to execute the query and return a list of facts in a CLIPS multifield value.基本上，您使用 eval 函数来执行查询并返回 CLIPS 多字段值中的事实列表。 You retrieve the facts from the multifield and then use the getFactSlot function to retrieve specific slot values.您从多字段中检索事实，然后使用 getFactSlot 函数检索特定的槽值。

Answer 2

   FactAddressValue fv = (FactAddressValue) ((MultifieldValue) clips.eval("(find-fact ((?f flower_name)) TRUE)")).get(0); // "flower_name"  is deftemplate name 

   String ou = fv.getFactSlot("name").toString() ; // "name" is the slot name 
    //String ou = value.toString() ; 
    System.out.println(ou) ;
