什麼,如果可能的話,將是實現以下所需的功能,我想很好地解決了:Java的泛型施放參數類型
- 蒙上了程序的返回類型的類型常規參數,例如,
// Foo and Bar are two types of Common
interface Common{}
interface Foo extends Common {}
interface Bar extends Common {}
// Example interface
public List<? extends Common> getFeatureByType(Class<? extends Common> clazz);
// Example of what I want to achieve by using the (or a similar) interface.
// Can this be achieve without using typecasting to (List<Bar>) or (List<Foo>)
// and @SuppressWarning("unchecked") ?
List<Bar> bars = getFeatureByType(Bar.class);
List<Foo> foos = getFeatureByType(Foo.class);
這是真棒,謝謝! – 2010-08-09 13:24:55
