我试图在复选框上强制单选,类似于html"select"

我有一个简单的html表:

<tr ng-repeat="subscription in entities">
    <td>
        <input type="checkbox" ng-checked="isChecked(subscription)" ng-click="toggleSelection(subscription)"/>
    </td>
</tr> 

然后我有一些简单的控制器函数用于上面的指令:

$scope.isChecked = function(entity) {
    return $scope.checkedEntity === entity;
};

$scope.toggleSelection = function(entity) {
    entity.checked = !entity.checked;
    if (entity.checked) {
        $scope.checkedEntity = entity;
    } else {
        $scope.checkedEntity = null;
    }
};

不幸的是它不起作用,我想我刚刚发现了...... ng-click有0优先级,而ng-checked有100.

这个问题有优雅的解决方案吗？

我基本上是在尝试做这样的事情：

interface gen1<T> {
    constructor(param: T);
}
interface gen2<T> {
    constructor(param: gen1<any>);
}
class genImpl implements gen2<any> {
    constructor(param: gen1<any>) {

    }
}

但得到错误：

Class 'genImpl' incorrectly implements interface 'gen2<any>'.
  Types of property 'constructor' are incompatible.
    Type 'Function' is not assignable to type '(param: gen1<any>) => any'.
      Type 'Function' provides no match for the signature '(param: gen1<any>): any'.
