Example: /aaa/bbb => /aaa /aaa/bbb/ccc => /aaa/bbb /aaa/bbb/ccc[@x='1' and @y="/aaa[name='z']"] => /aaa/bbb Because the patterns inside the square brackets might contain brackets within quotes, I decided to try to achieve this with the use of regular expressions. Here's a code snippet: string input = "/aaa/bbb/ccc[@x='1' and @y=\"/aaa[name='z'] \"]"; // ^-- remove space for no loop string pattern = @"/[a-zA-Z0-9]+(\[(

Now when the transaction of the EJB times out, will that cause the infinite loop thread to break or container will stop the thread running the infinite loop. 回答1: Now when the transaction of the EJB timesout, will that cause the infinite loop thread to break or container will stop the thread running the infinte loop. This answer is based on reverse-engineering that I performed a couple of years back on OC4J 10.3.x, WebSphere

Most examples seems to target the following: Have a timer spawn a new thread that will do some work, with infinite threads Spawn a specific number of threads, each with a timer that does something On a regular basis do some work What I am trying to accomplish is: Have a timer running to regularly spawn a thread This thread may or may not take longer than the timer-tick Have a limit to how many threads can be spawned When a thread finishes, give

Presently if I do rmmod it gives me notice that module is still busy and after some time kernel panics. while ( 1 ) { ....... } Is there any trick through which I could run infinite loop till I unload the module. 回答1: In which context does this loop run? This is a very important question. If init_module runs it, then the insmod process will never end, which is quite bad. If some system call runs it, then the system call won't return,

Inside the method implementation I use BigDecimal to get the nth Fibonacci number then I use method toBigInteger() to get the number as a BigInteger object and that's surely because I am working with huge numbers in my application. I keep getting correct results until I pass 1475 as an argument for my method. I get NumberFormatException: Infinite or NaN in this case without any clear reason for me. Could you please explain me why am I getting this exception? Here's my method:

The maximum recursion 100 has been exhausted before statement completion. So I put OPTION (maxrecursion 0) or OPTION (maxrecursion 32767) on my query, because I don't want to limit the records. But, the result is the query takes forever to load. How do I solve this? Here's my code: with cte as( -- Anchor member definition SELECT e.SponsorMemberID , e.MemberID, 1 AS Level FROM tblMember AS e where e

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I'm only beginning to become familiar with the concept of kinds, so bear with me if I am not formulating my questions well... Values have Types: 3 :: Int [1,2,3] :: [Int] ('c',True) :: (Char,Bool) Types have Kinds: the type 'Int' has kind * the type '[Int]' also has kind * but the type constructor [] has kind * -> * similarly, the type (Char,Bool) has kind * but the type constructor (,) has kind * -> * -> * What do Kinds have? Do they kinds have ilk, or genres, or breeds, or varieties? How far does this sequence of abstraction go? Do we stop
