    Hi All I am trying to to override a binding in a child injector that was already configured in a base injector. like that : public class PersistenceModule extends Abstract{ @Override protected void configure() { bind(IProductPersistenceHelper.class).to(ProductPersistenceHelper.class); } } then : Injector injector = Guice.createInjector(new PersistenceModule()); injector.createChildInjector(new AbstractModule(){ @Override protected void configure() { bind(IProductPersistenceHelper.class).to(MockProductPersistenceHelper.class); } }) Guice is complaining that it has already a binding for that. Are there any patterns or best practices for that problem ?

  • C++: incorrect swapping of nodes in linked list

    - by Dragon
    I have 2 simple structures: struct Address { char city[255]; }; typedef Address* AddressPtr; struct Person { char fullName[255]; Address* address; Person* next; }; typedef Person* PersonPtr; The Person structure forms the Linked list where new elements are added to the beginning of the list. What I want to do is to sort them by fullName. At first I tried to swap links, but I lost the beginning of the list and as a result my list was sorted partially. Then I decided to sort list by swapping the values of nodes. But I get strange results. For a list with names: Test3, Test2, Test1, I get Test3, Test3, Test3. Here is my sorting code: void sortByName(PersonPtr& head) { TaskPtr currentNode, nextNode; for(currentNode = head; currentNode->next != NULL; currentNode = currentNode->next) { for(nextNode = currentNode->next; nextNode != NULL; nextNode = nextNode->next) { if(strcmp(currentNode->fullName, nextNode->fullName) > 0) { swapNodes(currentNode, nextNode); } } } } void swapNodes(PersonPtr& node1, PersonPtr& node2) { PersonPtr temp_node = node2; strcpy(node2->fullName, node1->fullName); strcpy(node1->fullName, temp_node->fullName); strcpy(node2->address->city, node1->address->city); strcpy(node1->address->city, temp_node->address->city); } After the sorting completion, nodes values are a little bit strange. UPDATED This is how I swapped links void swapNodes(PersonPtr& node1, PersonPtr& node2) { PersonPtr temp_person; AddressPtr temp_address; temp_person = node2; node2 = node1; node1 = temp_person; temp_address = node2->address; node2->address = node1->address; node1->address = temp_address; }

  • Is it bad practice to declare an array mid-function...

    - by Maximus
    In C, which would be more proper... void MyFunction() { int* array; int size; //do a bunch of stuff size = 10; array = (int*)(sizeof(int)*size); //do more stuff... //no longer need array... free(array); } Or is something like this okay? void MyFunction() { int size; //do a bunch of stuff size = 10; array[size]; //do more stuff... } The malloc uses the heap instead of the stack, so I suppose if you know size is going to be very large you'd want to malloc... but if you're quite certain size will be small enough, would the second method be reasonable?

    - by AlphaAndOmega
    I've been trying to add audio to a project I've been doing.

  • std::make_shared as a default argument does not compile

    - by Mark Bryant
    In Visual C++ (2008 and 2010), the following code does not compile with the following error: #include <memory> void Foo( std::shared_ptr< int > test = ::std::make_shared< int >( 5 ) ) { } class P { void Foo( std::shared_ptr< int > test = ::std::make_shared< int >( 5 ) ) { } }; error C2039: 'make_shared' : is not a member of '`global namespace'' error C3861: 'make_shared': identifier not found It is complaining about the definition of P::Foo() not ::Foo(). Does anybody know why it is valid for Foo() to have a default argument with std::make_shared but not P::Foo()?

  • Can't record or play with a simple recorder?

    - by user1280535
    I have 2 classes, a record and a player. In my main scene, I create an instance of them and play and record. But, as I see, it only records and somehow does not play (the file is not there!) Here is the code for both : -(void)record { NSArray *dirPaths; NSString *docsDir; NSString *sound= @"sound0.caf" ; dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) ; docsDir = [dirPaths objectAtIndex:0]; NSString *soundFilePath = [docsDir stringByAppendingPathComponent:sound]; NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath]; NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithFloat: 44100.0], AVSampleRateKey, [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey, [NSNumber numberWithInt: 1], AVNumberOfChannelsKey, [NSNumber numberWithInt: AVAudioQualityMax], AVEncoderAudioQualityKey, nil]; NSError *error; myRecorder = [[AVAudioRecorder alloc] initWithURL:soundFileURL settings:settings error:&error]; if (myRecorder) { NSLog(@"rec"); [myRecorder prepareToRecord]; myRecorder.meteringEnabled = YES; [myRecorder record]; } else NSLog( @"error" ); } I can see the log of rec. -(void)play { NSArray *dirPaths; NSString *docsDir; dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); docsDir = [dirPaths objectAtIndex:0]; NSString *soundFilePath1 = @"sound0.caf" ; NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath1]; BOOL isMyFileThere = [[NSFileManager defaultManager] fileExistsAtPath:soundFilePath1]; if(isMyFileThere) { NSLog(@"PLAY"); avPlayer1 = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:NULL]; avPlayer1.volume = 8.0; avPlayer1.delegate = self; [avPlayer1 play]; } } I DONT SEE THE LOG OF PLAY ! I call them both with: recInst=[recorder alloc]; //to rec [recInst record]; plyInst=[player alloc]; //play [plyInst play]; and to stop the recorder: - (void)stopRecorder { NSLog(@"stopRecordings"); [myRecorder stop]; //[myRecorder release]; } What's wrong here?

  • Contacts activity doesn't return data

    - by Mike
    In my app I simply open the list of activities and when a contact is clicked I attempt to retrieve the name of the contact selected and put it into a string.

  • Calling class in Java after editing file used in as source for table

    - by user2892290
    I'm currently working on a project, I'll try to subrscibe first. I save data into text file, that I use as a source for browser of that data. The browser is based on table that contains the data. I have to rewrite the source file everytime I delete or edit data. That's where the problem comes in. After deleting or editing data I call a method to create the table again, but the table never creates. Is it possibly made by editing the file and calling the method right after that? If I restart my app the table is successfully created with right data. Take in note that I don't get any error message. This is the method I use for loading data from source file: try (BufferedReader input1 = new BufferedReader(new FileReader("./src/data.src"))) { int lines = 0; while (input1.read() != -1) { if (!(input1.readLine()).equals("")) { lines++; } } input1.close(); if (lines == 0) { JOptionPane.showMessageDialog(null, "No data to load, create a note first!"); new Writer().build(frame); } else { try (BufferedReader input = new BufferedReader(new FileReader("./src/data.src"))) { Game[] g = new Game[lines]; String currentLine; String[] help; int counter = 0; while (lines > 0) { currentLine = input.readLine(); help = currentLine.split("#"); g[counter] = new Game(help[0],help[1], help[2], help[3], help[4], help[5], help[6], help[7], help[8], help[9]); counter++; lines--; } input.close(); final JButton bButton = new backButton().create(frame, mPanel); build(g, frame, bButton); mPanel.add(panel); mPanel.add(panel2); mPanel.add(searchPanel); mPanel.add(bButton); bButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR)); panel.removeAll(); frame.setCursor(Cursor.getDefaultCursor()); } }); mPanel.setPreferredSize(new Dimension(1000, 750)); panel.setBorder(new EmptyBorder(10, 10, 10, 10)); frame.setLayout(new FlowLayout()); frame.add(mPanel); frame.pack(); JMenuBar menuBar = new Menu().create(frame, mPanel); frame.setJMenuBar(menuBar); frame.setVisible(true); Rectangle rec = GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds(); int width = (int) rec.getWidth(); int height = (int) rec.getHeight(); frame.setBounds(1, 3, width, height); frame.addComponentListener(new ComponentAdapter() { @Override public void componentMoved(ComponentEvent e) { frame.setLocation(1, 3); } }); And this is the method I use for creating the table: String[][] tableData = new String[g.length][9]; for (int i = 0; i < tableData.length; i++) { tableData[i][0] = g[i].getChampion(); tableData[i][1] = g[i].getRole(); tableData[i][2] = g[i].getEnemy(); tableData[i][3] = g[i].getDifficulty(); tableData[i][4] = g[i].getResult(); tableData[i][5] = g[i].getScore(); tableData[i][6] = g[i].getGameType(); tableData[i][7] = g[i].getPoints(); tableData[i][8] = g[i].getLeague(); } final JLabel searchLabel = new JLabel("Search for champion played."); final JButton searchButton = new JButton("Search"); final JTextField searchText = new JTextField(20); frame.setTitle("LoL Notepad - reading your notes"); JTable table = new JTable(tableData, columnNames); final JScrollPane scrollPane = new JScrollPane(table); scrollPane.setPreferredSize(new Dimension(980, 500)); panel2.setPreferredSize(new Dimension(1000, 550)); panel2.setVisible(false); panel2.setBorder(new EmptyBorder(10, 10, 10, 10)); panel3.setVisible(false); panel.setLayout(new FlowLayout()); panel.add(scrollPane); searchPanel.add(searchLabel); searchPanel.add(searchText); searchPanel.add(searchButton); searchButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { try { frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR)); search(g, searchText.getText(), frame, bButton); frame.setCursor(Cursor.getDefaultCursor()); } catch (IOException ex) { Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex); } } }); table.addMouseListener(new MouseAdapter() { @Override public void mousePressed(MouseEvent e) { if (e.getClickCount() == 1) { JTable target = (JTable) e.getSource(); panel.setVisible(false); searchPanel.setVisible(false); bButton.setVisible(false); int row = target.getSelectedRow(); specific(row, g, frame, bButton); } } });

Here I am creating one Simple validation for Edit text it only take A-Z and 0-9 value with minimum 5 and Maximum 8 character. I set the Maximum and other validation as follow. <EditText android:id="@+id/edittextKode_Listing" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginRight="5dp" android:layout_marginLeft="5dp" android:layout_alignTop="@+id/textKode_listing" android:layout_toRightOf="@+id/textKode_listing" android:maxLength="8" android:inputType="textCapCharacters" android:digits="0,1,2,3,4,5,6,7,8,9,ABCDEFGHIJKLMNOPQRSTVUWXYZ" /> but not able to set Minimum requirement. My Edit text is in alert dialog and i also apply the following code to solve this problem ` private void openInboxDialog() { LayoutInflater inflater = this.getLayoutInflater(); // declare dialog view final View dialogView = inflater.inflate(R.layout.kirim_layout, null); final EditText edittextKode = (EditText) dialogView.findViewById(R.id.edittextKode_Listing); final EditText edittextalamat = (EditText) dialogView.findViewById(R.id.edittextAlamat); edittextKode.setOnFocusChangeListener(new OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { // TODO Auto-generated method stub if(edittextKode.getText().toString().length() > 0){ if(edittextKode.getText().toString().length() < 5) { edittextKode.setError("Error"); Toast.makeText(GPSActivity.this, "Kode listing value not be less than 5", Toast.LENGTH_SHORT).show(); edittextKode.requestFocus(); } } } }); final AlertDialog.Builder builder = new AlertDialog.Builder(GPSActivity.this); builder.setTitle("Kirim").setView(dialogView) .setNeutralButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub gpsCoordinates = (TextView) findViewById(R.id.text_GPS_Coordinates); kode = edittextKode.getText().toString(); alamat = edittextalamat.getText().toString(); catatan = edittextcatatan.getText().toString(); pengirim = edittextPengirim.getText().toString(); if (kode.length() > 0 && alamat.length() > 0 && catatan.length() > 0 && pengirim.length() > 0) { message = "Kode listing : " + kode + "\nAlamat : " + alamat + " \nCatatan : " + catatan + " \n Pengirim : " + pengirim + "\nKoordinat GPS : " + gpsCoordinates.getText().toString(); sendByGmail(); } else { Toast.makeText( getApplicationContext(), "Please fill all three fields to send mail", Toast.LENGTH_LONG).show(); } } }); builder.create(); builder.show(); }` in this alert dialog i have two edittext i want to apply my validation on first edittext i called the setOnFocusChangeListener to check its minimum length on focus change and if length is less than 5 request for focus but it still type in second edittext. please help me out.

  • Validation of method parameters

    - by Anton Tsivarev
    I have a RESTful web service. For implementation using JAX-RS (Jersey). Have the following method: public void foo (@PathParam ("name") String uuid) { ... } I need to do validation of input parameters. And if data invalid throw WebApplicationException. I added my custom annotation CheckUuid (extends ): public void foo (@PathParam ("name") @CheckUuid String uuid) { ... } Is it possible to do validation using annotations on a stage when the method chosen, but not yet called? For example using PreProcessInterceptor?

  • Overload and hide methods in Java

    - by Marco
    Hi, i have an abstract class BaseClass with a public insert() method: public abstract class BaseClass { public void insert(Object object) { // Do something } } which is extended by many other classes. For some of those classes, however, the insert() method must have additional parameters, so that they instead of overriding it I overload the method of the base class with the parameters required, for example: public class SampleClass extends BaseClass { public void insert(Object object, Long param){ // Do Something } } Now, if i instantiate the SampleClass class, i have two insert() methods: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object); sampleClass.insert(Object object, Long param); what i'd like to do is to hide the insert() method defined in the base class, so that just the overload would be visible: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object, Long param); Could this be done in OOP?

  • Class Members Over Exports

  • Prevent Erroneous Property Assignment

    - by Gordon
    Porting android applications to iphone applications always gives me the following pattern that I accidentally create: - (void) myFunc:(id)prop { self.property = property; } Which instead should be: - (void) myFunc:(id)prop { self.property = prop; } This always causes my program to quietly break because property gets reset to its existing value rather than being set to the new value, 'prop'. I cannot name the parameter 'prop' to 'property' since the compile complains that the parameter masks the instance variables visibility. Is there a good way to avoid this situation? There are no compiler warnings. Is there a way to make xcode prevent this? I cannot see very many situations where you would set a property to the value of its underlying instance variable (maybe to trigger a KVO binding?), but I don't see myself doing that in majority of cases. I understand the above code is synthetic and should be done with @synthesize, but I am just using it as a simplified example to illustrate my point.

  • How to pass and set a CGFloat by reference?

    - by mystify
    I want to make an method which takes an CGFloat by reference. Could I do something like this? - (void)doStuff:(CGFloat*)floatPointer I guess this must look different than other object pointers which have two of those stars. Also I'm not sure if I must do something like: - (void)doStuff:(const CGFloat*)floatPointer And of course, no idea how to assign an CGFloat value to that floatPointer. Maybe &floatPointer = 5.0f; ? Could someone give some examples and explain these? Would be great!
