pooling - Java resource pool -

-

I have app data that stores data in XML when user asks for data, then XML is read in institutions , Which is then shown through a few-like-servlet.

My problem is, after every refresh, data for some kind of service has to be processed again and parsing XML is expensive. There is too much XML to store all data in memory.

I was thinking something like resource pooling, where the program asks the bridge, if the name in the pool is the unit with foo . If it is, then foo is returned from the pool, if not, the foo has been created from XML and saved in the pool.

Something like this: 

  unit unit = zero; Entity.setId (id); (Unit unitFormpool: pool.getAellientes ()) {if (entityFromPool.getId (.) Equals (entity.getId ())} {entity = entityFromPool (); IsInPool = True; } If (! INPool is) {entity = getEntityFromXML (); }

I have read about Apache object pooling , but if I understand it correctly, then I can not store the F store. With this, 5 different entities and then ask if there is a special ID with pool.

Is there a library that can help with my problem? thanks a lot!

If you are talking about the Commons pool, you can put a look at the interface.

A "Key" pooling interface.

A key pool contains a pool of examples of each key value.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
