QUESTION

Can one native method be called from another native method?

Asked 2019-Sep-25 at 08:50

I have a class in Java which contains certain native method declarations. It contains a call to detroy() within finalize method which is now deprecated. As an alternative to finalize, I arrived at AutoCloseable with try-with-resources. However the issue is that, the close() method provided by AutoCloseable which must be overridden in my JSQ class is conflicting with the existing native close method already defined in my code. If I can find an alternate place from which destroy can be called, that should suffice as a solution. Therefore, I'm attempting to call destroy() from the native close() which would be the last point where shdl would be used. Is this possible / allowed / recommended ? I don't have the option of removing or altering native close() which is why I'm attempting to make the call to destroy from native close.

Calling one native method from another is in fact permitted. At least, I did not receive any errors or warnings when I did this. But the call must include the full function name as expected of any native method - i.e. Java_com_project_package_JSQ_destroy and the parameters should include:

the JNI environment
jobject Object
parameters expected by the method. In this case, shdl

Therefore, the call must be like so:

QUESTION

How exactly is memory allocation taking place and how are Java and C interacting to keep track of the same object?

Asked 2019-Sep-24 at 07:37

I have a class containing a member variable of type long and a set of native method declarations. I believe the memory for the variable is being allocated in one of the native methods and the de-allocation is attempted in the finalize() method by calling another native method destroy. I understand that finalize is deprecated but prior to finding an alternative for finalize, I need to understand how the memory allocation is happening and how Java and C maintain sync through JNI and how this particular member variable is tracked. I will attempt to explain the scenario better with code snippets:

A Java long variable is guaranteed to be 64 bits wide, so it is enough to contain an address, even on a 64-bit system. The cast to long is just there to make the C++ type system happy. As you see, the SQ macro is used to convert this address back to a proper pointer to an sq_stsm_t object.

As for your second question: all the macro does is get rid of some typing work. The Java part of your program will always pass the long-typed shdl variable, so the SQ macro just provides easy access to the actual sq_stsm_t object.

Finally, new and delete in C++ go together: new allocates memory and calls the constructor, delete calls the destructor and frees the memory again. Note that "free" does not necessarily mean "give back to the OS", so your process's memory usage can remain the same after this delete operation.

As for the comment in your code: Java_com_project_package_JSQ_set_shdl tries to call the Java method boolean com.project.package.JSQ#set_JSQ_shdl(jlong), although it is not present in the code you pasted. I guess it is a simple setter for the shdl field?

As for your follow-up plans: implementing AutoCloseable is a good idea. You would need to create a native void close() method in your JSQ object which calls delete on the sq_stsm_t object stored in the shdl field and then replaces the shdl field with (jlong)nullptr.

R Simmer - "Number of keys and values don't match"

Asked 2019-May-31 at 14:53

I am trying to simulate a JSQ(d) (join-shortest-queue of d sampled queues) system but am having trouble executing my code. In this case, let us assume d=2. I wish to have job size determined upon arrival (the value of "X") as well as the selection of which 2 queues will be sampled and "JSQ-ed" (this could be done perhaps differently, though for my purposes beyond this minimal working example, these must be determined upon arrival).

QUESTION

how do I just show the profile Image next to the last message of an user in a chat

Asked 2017-Sep-29 at 19:19

I am using JSQ Messages Controller to add a chat feature to my app, but I also managed to create one on my own with a collectionview. However Injust can‘t figure out how to show the profile picture just next to the last message of an user. For example he writes 3 messages and no one else in the chat does write anything in between. Now I just want to show only next to the third message the profile picture. When I return the items (cells) I just can edit the item I am about to return (at indexPath.item) though. I can make sure that the message before (at indexPath.item - 1) has the same senderID. But I can‘t check if the cell at indexPath.item + 1) is from the same sender. Since I am not able to check the second one, I have no clue how to solve my problem. I hope you understood what I want to do.

First I would like to point you to the new project that is taking over JSQMessageViewController since JSQMessageViewController is deprecated, It is called MessageKit.

Make a function to determine if it is the last message in a set.

Twisted Session Cookie is Changing for Each Request

Asked 2017-Jul-19 at 13:12

For some reason after logging in, every POST request afterwards the Twisted session cookie changes. Why does this happen? I would expect the session uid to be the same until the connection is lost, or the user logs out.

Here is my code that causes the session to be different for each request:

Twisted Web sessions are cookie based. For the session to remain active with a client, they must respect the server's Set-Cookie response (save the cookie and re-send it with future requests).

If your client is something like curl, then:
