我正在尝试使用谓词，但我不能，因为方法重载正在起作用......
我想将过滤器与数组（varargs）一起使用，并且我想在谓词中使用内置方法，该方法将数组过滤为转换为列表。
这是错误：Predicates 类型中的方法 filter(Iterable, Predicate) 不适用于参数 (Class[], Predicate)
private static final Predicate<Method> isTestMethod = new Predicate<Method>() {
@Override
public boolean evaluate(Method input) {
return input.isAnnotationPresent(Test.class);
}
};
public static void testClasses(Class<?>... classes) {
for (Method method : filter(classes, isTestMethod)) {
}
}
这是谓词方法：
/**
* Returns the elements of <tt>unfiltered</tt> that satisfy a predicate.
*
* @param unfiltered An iterable containing objects of any type
* that will be filtered and used as the result.
* @param predicate The predicate to use for evaluation.
* @return An iterable containing all objects which passed the predicate's evaluation.
*/
public static <T> Iterable<T> filter(Iterable<T> unfiltered, Predicate<T> predicate) {
checkNotNull(unfiltered);
checkNotNull(predicate);
List<T> result = new ArrayList<T>();
Iterator<T> iterator = unfiltered.iterator();
while (iterator.hasNext()) {
T next = iterator.next();
if (predicate.evaluate(next)) {
result.add(next);
}
}
return result;
}
/**
* Returns the elements of <tt>unfiltered</tt> that satisfy a predicate.
*
* @param unfiltered An array containing objects of any type
* that will be filtered and used as the result.
* @param predicate The predicate to use for evaluation.
* @return An iterable containing all objects which passed the predicate's evaluation.
*/
public static <T> Iterable<T> filter(T[] unfiltered, Predicate<T> predicate) {
return filter(Arrays.asList(unfiltered), predicate);
}
