In this case, the list of lookups is the union of lookups referenced by all of those features, and these are all processed in their lookup list order. If the different features have been applied to different glyph sub-sequences for a string, each lookup is applied only to the sub-...
filter 的引元是 Predicate<T>,即从 T 到 boolean 的函数。过滤并产生一个新的流 Stream<String> longWords = words.stream().filter(w -> w.length() > 16); // longWords.getClass().getName(): java.util.stream.ReferencePipeline$2 System.out.println(longWords.collect(Collectors.toList()));...

unkonwn 类型未定时候使用 unknown 类型会比 any 更加安全。这个安全体现在,虽然它和 any 一样存储了任意类型的值,但是具体使用的时候,这个类型需要显式确定,由使用者进行指定将 unknown 转换成某一确定类型。 高级类型 union 组合类型 //let union:string | number ...
boolean await = threadLatchs.await(30, TimeUnit.SECONDS); // 判断是否超时 if (!await) { isError.set(true); } } catch (Throwable e) { e.printStackTrace(); isError.set(true); } if (!transactionStatuses.isEmpty()) { if (isError.get()) { ...
NOT is a logic operator that reverses a Boolean state, so NOT true equals false, and NOT false equals true. When a query calls for matching criteria, preceding the criteria construct with NOT flips this around and calls for records that specifically do not match the criteria. Our sample Clie...
