java - Serializing BTree to a file -

-

I'm trying to implement a BTree I work very much with trees and lots of small input Good work, which means that I have implemented the tree in memory, now I would like to play with large input, for which I have to write a tree in a file. I do not know where to start, I am using Java and I have not done much 'coding disk' coding any help would be very appreciated. If someone wants to help me with such an example which would be better.

If your BTree and its nodes are serialiable, you can use the object overputstream and fileoptrast in a file tree And write his content. It would be easy to test: write it in a .ser file, read it back, and see if you got the original BTree back.

There are some good examples in the package that will help you.

UPDATE: I do not see the case of your use to write dynamically because it is done according to the modifications or "do not want to write the whole tree."

It is impossible to slow down. It will take a long time to mirror each change in memory with related modification in the file.

If you are trying to implement your own database, then it makes sense to understand what is the scenario in your mind?

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
