示例1: testConsumed
import java8.util.stream.Stream; //导入方法依赖的package包/类
public void testConsumed() {
Stream<Integer> s1 = StreamSupport.stream(countTo(100));
try {
s1.forEach(i -> {});
// Adding onClose handler when stream is consumed is illegal
// handler must not be registered
checkISE(() -> s1.onClose(() -> fail("s1")));
} finally {
if (s1 != null) {
s1.close();
}
}
// close() must be idempotent:
// second close() invoked at the end of try-with-resources must have no effect
Stream<Integer> s2 = StreamSupport.stream(countTo(100));
try {
s2.close();
// Adding onClose handler when stream is closed is also illegal
checkISE(() -> s2.onClose(() -> fail("s2")));
} finally {
if (s2 != null) {
s2.close();
}
}
}
