请问typeOfT= ((Type) (classOfT))这种是什么写法

public Object fromJson(String json, Class classOfT)
throws JsonSyntaxException

 {
 //如下代码 ((Type) (classOfT))是什么意思
Object object = fromJson(json, ((Type) (classOfT)));
 return Primitives.wrap(classOfT).cast(object);
 }
public Object fromJson(String json, Type typeOfT)
    throws JsonSyntaxException
{
    if(json == null)
    {
        return null;
    } else
    {
        StringReader reader = new StringReader(json);
        Object target = fromJson(((Reader) (reader)), typeOfT);
        return target;
    }
}
