用于加强代码流程可读性的工具类

Java Language:

public class LayerResult {
    private List<Boolean> results = new ArrayList<Boolean>();
    private int layer = -1;

    public boolean get(){
        return results.get(layer);
    }

    public boolean set(boolean result){
        results.set(layer, result);
        return result;
    }

    public boolean and(boolean value){
        return set(get() && value);
    }

    public boolean or(boolean value){
        return set(get() || value);
    }

    public void in(boolean defaultValue){
        results.add(defaultValue);
        layer ++;
    }

    public boolean out(){
        layer --;
        return results.remove(layer + 1);
    }
}

 

Javascript Language:

var LayerResult = function(){
};
LayerResult.prototype = {
    results : [],
    layer : -1,
    get : function(){
        return results[layer]
    },
    set : function(value){
        results[layer] = value;
        return value;
    },
    and : function(value){
        return this.set(this.get() && value);
    },
    or : function(value){
        return this.set(this.get() || value);
    },
    in : function(defaultValue){
        results.push(defaultValue);
    },
    out : function(){
        return results.pop();
    }
};
