java - 将一系列信号送入电线

Question

我得到了private List<Wire> inputs和一个方法public void feed(List<Signal> inSigs) 。我必须更改 List<Wire> inputs 中的信号(最初每个信号都是 ==Signal.X)与 inSigs方法的参数中给出 feed() 。这就是我一直遇到的麻烦。如何通过传递 inSigs 更改列表输入的状态(注意:参数的类型为 <Signal> )？我已经完成了一些工作，但在 setSignal(x) 下不断出现并下划线错误。我附加了两个类(class)(下面的 Gate 和 Wire)

import java.util.*;

    public abstract class Gate implements Logic {

        private List<Wire> inputs;
        private Wire output;
        private String name;

        public Gate(String name, List<Wire> ins, Wire out)
        {
            this.name = name;
            this.output = out;

            if(ins.size() == 0 || ins.isEmpty())
                throw new ExceptionLogicParameters(false, 1, 0);
            else 
                this.inputs = ins;
        }

        @Override
        public void feed(List<Signal> inSigs)
        {

            for(Signal x: inSigs)
                inputs.setSignal(x);
        }

        @Override
        public void feed(String name)
        {
            ((Wire) inputs).setName(name);
        }

    }

    public class Wire {

        private Signal signal;
        private String name;

        public Wire(String name)
        {
            this.name = name;
            this.signal = Signal.X;
        }

        @Override
        public String toString()
        {
            return "\""+ this.name+":"+this.signal+"\"";
        }

        @Override
        public boolean equals(Object other)
        {
            if(other instanceof Wire)
            {
                Wire leftHandside = (Wire)other;
                return this.name.equals(leftHandside.name) && this.signal == leftHandside.signal;
            }
            else 
                return false;
        }

        public Signal getSignal()
        {
            return this.signal;
        }

        public String getString()
        {
            return this.name;
        }

        public void setSignal(Signal signal)
        {
            this.signal = signal;
        }

        public void setName(String name)
        {
            this.name = name;
        }

    }

Answer 1

您的代码和问题的阅读方式存在很多歧义。

我假设信号列表与您的私有(private)电线列表大小相同，然后:

public void feed(List<Signal> inSigs) {
  // Needs precondition that inSigs.size() == input.size()
  for (int i = 0; i < inSigs.size(); i++) {
    inputs.get(i).setSignal(inSigs.get(i));
  }
}

否则，您需要一种将信号映射到电线的方法(可能通过索引)。
