是用Goal作为内部类。添加@Goal标记。
package a1;
import java.util.HashMap; import java.util.Map;
import jadex.bdiv3.BDIAgent;
import jadex.bdiv3.annotation.Belief; import jadex.bdiv3.annotation.Goal; import jadex.bdiv3.annotation.Plan; import jadex.bdiv3.annotation.Trigger; import jadex.micro.annotation.Agent; import jadex.micro.annotation.AgentBody; import jadex.micro.annotation.AgentCreated; import jadex.micro.annotation.Description; @Agent
@Description(\) // @Plans(@Plan(body=@Body(TranslatePlan.class))) publicclassTranslateEngChBDI { @Agent
protected BDIAgent translateAgent;
@Belief
protected Map
@AgentCreated publicvoid init() {
this.wordTable = new HashMap
wordTable.put(\, \牛奶\);
wordTable.put(\, \香蕉\);
wordTable.put(\, \学校\);
wordTable.put(\, \老师\);
wordTable.put(\, \科学\); } @Goal
publicclassTranslateEngCh { protected String eword; protected String cword;
public TranslateEngCh(String eword) { this.eword = eword;
}
public String getEword() { return eword; }
publicvoid setEword(String eword) { this.eword = eword; }
public String getCword() { return cword; }
publicvoid setCword(String cword) { this.cword = cword; } }
@Plan(trigger = @Trigger(goals = TranslateEngCh.class)) publicvoid translateEngChPlan(TranslateEngCh goal) { goal.setCword(wordTable.get(goal.getEword())); }
@AgentBody
publicvoid body() {
String ewordString = \;
TranslateEngCh goal = (TranslateEngCh) translateAgent.dispatchTopLevelGoal(
new TranslateEngCh(ewordString)).get();
System.out.println(\翻译结果:\ + ewordString + \\ + goal.getCword()); } }
goal定义完成之后,是被agent来调用的。为了实现这个goal,那么就需要有Plan来支持,最终完成某个目的。 记住两点:
1. agent.dispatchTopLevelGoal();
2. 调用goal以后,需要Plan来对goal进行处理。
上述程序的结果,显示为了达成某个目标,定义Plan来处理goal。
这里我们是用了类的get和set方法来操作goal的成员变量。如何能够实现在类的外部直接对成员变量进行操作呢?
3. 使用Goal的参数和结果(optionally)
使用目标的参数和结果能够节省很多代码。并且保证目标的安全性。 主要的实现形式为:@GoalParameter 和@GoalResult
