英文:
Is there a simpler term that stands for "non-destructive setter"?
问题
在这样的代码中，setValue 方法通常一般被称为“setter”，但是像 withValue 方法这样的（即返回其字段被更改的新对象）一般被称为什么？
class MyClass {
private int value;
public MyClass(int value) {this.value=value;}
// 一个获取器
public int getValue() {return value;}
// 一个（破坏性的）setter
public void setValue(int value) {this.value=value;}
// 一个（非破坏性的）setter <- 是否有比这更简单的术语？
public MyClass withValue(int value) {return new MyClass(value);}
}
英文:
In such a code, setValue method is usually called as "setter" in general, but how withValue method, (i.e. returns new object whose fields(s) is/are changed), is called in general?
class MyClass {
private int value;
public MyClass(int value) {this.value=value;}
// a getter
public int getValue() {return value;}
// a (destructive) setter
public void setValue(int value) {this.value=value;}
// a (non-destructive) setter <- Is there a simpler term than this?
public MyClass withValue(int value) {return new MyClass(value);}
}

通常这些方法的前缀是 with：
MyClass alternateVersion = myClass.withValue(5);
英文:
The usual prefix for those methods is with:
MyClass alternateVersion = myClass.withValue(5);
