Is there a version of the removeElement function in Go for the vector package like Java has in its Vector class?
问题
我正在将一些Java代码移植到Google的Go语言中，除了一个非常顺利的移植之外，我正在转换所有的代码，但我卡在了一个部分。我的Go代码如下，我所说的部分被注释掉了：
func main() {
var puzzleHistory *vector.Vector;
puzzleHistory = vector.New(0);
var puzzle PegPuzzle;
puzzle.InitPegPuzzle(3,2);
puzzleHistory.Push(puzzle);
var copyPuzzle PegPuzzle;
var currentPuzzle PegPuzzle;
currentPuzzle = puzzleHistory.At(0).(PegPuzzle);
isDone := false;
for !isDone {
currentPuzzle = puzzleHistory.At(0).(PegPuzzle);
currentPuzzle.findAllValidMoves();
for i := 0; i < currentPuzzle.validMoves.Len(); i++ {
copyPuzzle.NewPegPuzzle(currentPuzzle.holes, currentPuzzle.movesAlreadyDone);
copyPuzzle.doMove(currentPuzzle.validMoves.At(i).(Move));
// Go语言的Vector没有像Java的Vector那样可以删除元素的函数
//puzzleHistory.removeElement(currentPuzzle);
copyPuzzle.findAllValidMoves();
if copyPuzzle.validMoves.Len() != 0 {
puzzleHistory.Push(copyPuzzle);
}
if copyPuzzle.isSolutionPuzzle() {
fmt.Printf("Puzzle Solved");
copyPuzzle.show();
isDone = true;
}
}
}
}
如果没有可用的版本，我相信没有...有人知道我该如何自己实现这样的功能吗？
英文:
I am porting over some Java code into Google's Go language and I converting all code except I am stuck on just one part after an amazingly smooth port. My Go code looks like this and the section I am talking about is commented out:
func main() {
var puzzleHistory * vector.Vector;
puzzleHistory = vector.New(0);
var puzzle PegPuzzle;
puzzle.InitPegPuzzle(3,2);
puzzleHistory.Push(puzzle);
var copyPuzzle PegPuzzle;
var currentPuzzle PegPuzzle;
currentPuzzle = puzzleHistory.At(0).(PegPuzzle);
isDone := false;
for !isDone {
currentPuzzle = puzzleHistory.At(0).(PegPuzzle);
currentPuzzle.findAllValidMoves();
for i := 0; i < currentPuzzle.validMoves.Len(); i++ {
copyPuzzle.NewPegPuzzle(currentPuzzle.holes, currentPuzzle.movesAlreadyDone);
copyPuzzle.doMove(currentPuzzle.validMoves.At(i).(Move));
// There is no function in Go's Vector that will remove an element like Java's Vector
//puzzleHistory.removeElement(currentPuzzle);
copyPuzzle.findAllValidMoves();
if copyPuzzle.validMoves.Len() != 0 {
puzzleHistory.Push(copyPuzzle);
}
if copyPuzzle.isSolutionPuzzle() {
fmt.Printf("Puzzle Solved");
copyPuzzle.show();
isDone = true;
}
}
}
}
If there is no version available, which I believe there isn't ... does anyone know how I would go about implementing such a thing on my own?

目前Go语言不支持泛型相等运算符。因此，您需要编写一个迭代向量并删除正确元素的代码。
英文:
Right now Go doesn't support generic equality operators. So you'll have to write something that iterates over the vector and removes the correct one.
