java - How to wait for list of `Future`s created using different `ExecutorServices` -


OK, so I know that the first answer / comment here is "using a executable service Use and use invokeAll ".

That's why I have a list of thread pools ( Executives Services ) and this is a good reason (which I will not bother with people). What I need to do is use callable on each thread pool submit (no problem). Now I have a collection of future examples, each created on a different executable service , and I want to wait for them to complete ( Be able to provide more

Is there an existing class that will do this ( wrap the list of future frequencies and allow the wait until everything is done )? If not, appreciate the tips on a skilled mechanism

For each, with the expiration of received was thinking of calling, but the total time passed for each call has to be calculated.

I have seen this post but instead of wrapping their list, the future is spread out.

Per Louis's comment, which I was looking for

This will make me wait for everyone to complete and then fail

The rules of the law!

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
