==What are extensions==
 +
Extensions in OpenOffice extends the capability of the OpenOffice program. Extension can be for OpenOffice Writer, Calc, Presentation, Database or for the core OpenOffice. For OpenOffice writer, there may be extensions that extends the dictionary feature of OpenOffice so that user can use a French dictionary. Similarly there may be extensions that adds extra grammar features. An extension for Calc might do a complex calculation like mortgage calculation or filter data in certain way.
 +
A popular extension might become part of the core program in a future release.
 +
Extensions for OpenOffice can downloaded at http://extensions.services.openoffice.org

==How to install extensions==
 +
To install an extension
 +
* First download an extension from http://extensions.services.openoffice.org
 +
* Then open OpenOffice Writer or Calc. On the top menu, click Tools->Extension Manager...
 +
[[Image:install_extension01.png|border|none|thumb|200px|Installing an Extension]]
 +
* Click Add... and select the .oxt file (extension file) you downloaded.
 +
[[Image:install_extension02.png|border|none|thumb|200px|Installing an Extension]]
 +
Usually, you should see a new button or menu item related to the extension you install. Since extension can do different things, sometimes you might not see any button or menu item. That extension might only appear and work on context menu. So if you cannot find it, check the extension's read-me file or manual.

----
 +
OpenOffice.org objects and methods, such as paragraphs, spreadsheets, and fonts, are accessible to OpenOffice.org Basic through the OpenOffice.org application programming interface, or API. Through the API, for example, documents can be created, opened, modified and printed. The API can be used not only by OpenOffice.org Basic, but also by other programming languages, such as Java and C++. The interface between the API and various programming languages is provided by something called Universal Network Objects (UNO).

===Factory method design pattern===
 +
OpenOffice.org development heavily uses the Factory method design pattern.
 +
Design patterns are conventional templates that describes how to solve common software problems. Since most developers are familiar with the patterns, they can recognize a pattern in others source code. That makes working in teams easier. There are many popular design patterns. One of them is Factory method pattern.
 +
Factory method pattern is a type of creational pattern. Creational pattern pattern solves problems related to creating. Factory pattern solves two major problem generally faced by developers.
 +
1. To reduce too many new operator usage
 +
:When working on a large software, numerous instances of classes are created continuously at the runtime. The programmer cannot predict what the user is going to do. So at any given time, the programmer doesn't know what object is create. For example, To create a new document, the user might click new text document or new spreadsheet document. There would several possibilities about what the user is going to do. So, a factory class is assigned to do all  these repetitive work of creating a new instance of what the user wants. By separating these repetitive object creations into a factory class, when new classes are added, only the factory class need to be updated.
 +
2. To create object without knowing its class name.
 +
:When using the concrete classes, the developer has to remember the class names. In factory pattern, choosing what type of object to be created is delegated to the factory class. Usually this is done by sending a parameter. Based on the parameter passed to the factory, the factory creates an instance of a certain type/class.
 +
[[Image:factorypattern.gif|border|none|thumb|300px|Factory Method Pattern]]
 +
<pre>
 +
public final class DocumentFactory {
 +
  XDocument document;
 +
  XDocument getDocument(String type){
 +
  if(type.equals("text"){
 +
      document = new TextDocument();
 +
  }
 +
  else if(type.equals("sheet"){
 +
      document = new SpreadSheet();
 +
  }
 +
  return document;
 +
  }
 +
}
 +
</pre>
 +
<pre>
 +
public interface XDocument{
 +
  open();
 +
}
 +
</pre>
 +
<pre>
 +
public class TextDocument implements XDocument{
 +
  //concrete class for Text documents
 +
  open(){
 +
      //method to open text document
 +
      System.out.println("opening a text document...");
 +
  }
 +
}
 +
</pre>
 +
<pre>
 +
public class SpreadSheet implements XDocument{
 +
  //concrete class for spreadsheet documents
 +
  open(){
 +
    //method to open spreadsheet document
 +
    System.out.println("opening a spreadsheet document...");
 +
  }
 +
}
 +
</pre>
 +
<pre>
 +
class DocumentProgram{
 +
  public static void main(String[] args){
 +
      XDocument doc = df.getDocument("text");  //this just created an instance of TextDocument without knowing its class name.
 +
      doc.open();
 +
  }
 +
}
 +
</pre>
 +
===Singleton Pattern===
 +
In Singleton Pattern, the class can only create a single instance. We want a class to have only a single instance for various reasons.
 +
Sometimes, we want use a global object to keep information about your program. This object should not have any copies. This information might be things like configuration of the program, or a master object that manages pools of resources. So when you need a resource, you ask the master object to get it for you. Now if there were many copies of this master object, you would not know whom to ask for that resource. This single object should not be allowed to have copies. Singleton Pattern forces this rule so that programmer doesn't have to remember about not creating copies. Singleton pattern will create an instance if it doesn't exist and will not create any new instance if an instance already exist. It will just return a reference to that single instance.
 +
<pre>
 +
class ProgramConfiguration{
 +
    public ProgramConfiguraiton(){
 +
        //default constructor code
 +
    }
 +
}
 +
</pre>
 +
A new instance of a class is created by the constructor. Most of the time, we have a public constructor, which is called to create a new instance. Since we want to prohibit multiple instance, we have to restrict access to the constructor. This is done by making the constructor private.
 +
<pre>
 +
class ProgramConfiguration{
 +
    private ProgramConfiguration(){
 +
        //default private constructor code
 +
    }
 +
}
 +
</pre>
 +
then we create a static public method that will make sure that only one instance lives in the whole program.
 +
<pre>
 +
class ProgramConfiguration{
 +
    private static ProgramConfiguration _configObject;
 +
    private ProgramConfiguration(){
 +
        //default private constructor code
 +
    }
 +
    public getInstance(){
 +
        /*
 +
        if an instance exist return that instance otherwise
 +
        call the constructor to create an instance and return it.
 +
        */
 +
        if(_configObject = null){
 +
        _configObject = ProgramConfiguration();
 +
        }
 +
        return _configObject;
 +
    }
 +
}
 +
</pre>
 +
So anytime you want to get that single object, you call the getInstance() method.
 +
<pre>
 +
main(){
 +
    /*
 +
    no access to default constructor. so if you did
 +
    ProgramConfiguration pc = new ProgramConfiguration();
 +
    you will get compilation error.
 +
    */
 +
    ProgramConfiguration pc = ProgramConfiguration.getInstance();
 +
    ProgramConfiguration newpc = ProgramConfiguration.getInstance();
 +
    /*
 +
    in the above code pc and newpc both point to the same static object. when
 +
    getinstance() is called for the second time, it finds that _configObject is not null
 +
    anymore, so it doesn't call the constructor to create any new instance.
 +
    */
 +
}
 +
</pre>

OpenOffice Extensions

What are extensions

Extensions in OpenOffice extends the capability of the OpenOffice program. Extension can be for OpenOffice Writer, Calc, Presentation, Database or for the core OpenOffice. For OpenOffice writer, there may be extensions that extends the dictionary feature of OpenOffice so that user can use a French dictionary. Similarly there may be extensions that adds extra grammar features. An extension for Calc might do a complex calculation like mortgage calculation or filter data in certain way. A popular extension might become part of the core program in a future release. Extensions for OpenOffice can downloaded at http://extensions.services.openoffice.org

How to install extensions

To install an extension

Installing an Extension
  • Click Add... and select the .oxt file (extension file) you downloaded.
Installing an Extension

Usually, you should see a new button or menu item related to the extension you install. Since extension can do different things, sometimes you might not see any button or menu item. That extension might only appear and work on context menu. So if you cannot find it, check the extension's read-me file or manual.

Install OpenOffice.org and SDK

OpenOffice.org program and SDK can be installed through package manager program, such as apt-get, yum, merge and pacman. Also, several GUI font-end for package manager programs are available to make installation easier. On Ubuntu, Synaptic is good choice. YumEx is the best option on Fedora.

  • Ubuntu:
    • With aptitude: launch a terminal and enter following command
    sudo aptitude install openoffice.org openoffice.org-dev
    If you want SDK examples and documentations, install openoffice.org-dev-doc as well.
    sudo aptitude install openoffice.org-dev-doc
    • With Synaptic: Go to menu: System -> Administration -> Synaptic Package Manager. Search openoffice, and click openoffice.org, openoffice.org-dev, openoffice.org-dev packages, then click Mark for Installation and hit Apply on toolbar.
  • Fedora:
    • With Yum:
    sudo yum install {package name}
    To-Do: replace {package name} with real package names under Fedora
    • With YumEx:
    YumEx does not come with distribution. You needed to be installed manually.
    sudo yum install yumex
    After installation, launch YumEx, search openoffice, select those packages and install.

Note: On Fedora, sudo is not set by default. You can add you account to wheel user group so that you can use sudo. Also, you may use su to change to root, and run yum to install packages.
Note: On Ubuntu, if you use OpenOffice.org program that comes with distribution, and try to install SDK that is downloaded from OpenOffice.org website, you may encounter dependency issue. You should the SDK that come with distribution.

Install NetBean, and OpenOffice.org Extension Development Plugin

NetBean can be installed through package manager as well. Package name is netbeans. Ubuntu: 

sudo aptitude install netbeans

Fedora: 

sudo yum install netbeans

To-Do: need someone check if the packages name for Netbeans on Fedora is netbeans. After installation, you can install development plugin in NetBean. Lunch NetBean, select Plugins under Tool menu. Then switch to Available Plugins tab, and install OOo API plugin. Finally, select Options under Tool menu, and go to Miscellaneous -> OOo API Plugins tab. Fill in the path to OpenOffice.org program and SDK. Path is provide in following section.

You will need the following software: OpenOffice.org OpenOffice.org SDK Netbeans Make sure you install OpenOffice and the SDK before running Netbeans. First Open Netbeans and go to: Tools -> Plugins Go the Available Plugins tab and look for OpenOffice.org API Plugin and check the box beside it. It will prompt you to install and click the Install button on the bottom of the list. The plugin will install. To change the setting for the plugin go to: Tools -> Options -> Miscellaneous -> OOo API Plugin There you will see the directory path to the installation of both OO and The SDK. If you need to change it then you can make the corrections here.

OpenOffice.org API (Application Programming Interface)

http://api.openoffice.org/

OpenOffice.org objects and methods, such as paragraphs, spreadsheets, and fonts, are accessible to OpenOffice.org Basic through the OpenOffice.org application programming interface, or API. Through the API, for example, documents can be created, opened, modified and printed. The API can be used not only by OpenOffice.org Basic, but also by other programming languages, such as Java and C++. The interface between the API and various programming languages is provided by something called Universal Network Objects (UNO).

Factory method design pattern

OpenOffice.org development heavily uses the Factory method design pattern. Design patterns are conventional templates that describes how to solve common software problems. Since most developers are familiar with the patterns, they can recognize a pattern in others source code. That makes working in teams easier. There are many popular design patterns. One of them is Factory method pattern. Factory method pattern is a type of creational pattern. Creational pattern pattern solves problems related to creating. Factory pattern solves two major problem generally faced by developers. 1. To reduce too many new operator usage

When working on a large software, numerous instances of classes are created continuously at the runtime. The programmer cannot predict what the user is going to do. So at any given time, the programmer doesn't know what object is create. For example, To create a new document, the user might click new text document or new spreadsheet document. There would several possibilities about what the user is going to do. So, a factory class is assigned to do all these repetitive work of creating a new instance of what the user wants. By separating these repetitive object creations into a factory class, when new classes are added, only the factory class need to be updated.

2. To create object without knowing its class name.

When using the concrete classes, the developer has to remember the class names. In factory pattern, choosing what type of object to be created is delegated to the factory class. Usually this is done by sending a parameter. Based on the parameter passed to the factory, the factory creates an instance of a certain type/class.
Factory Method Pattern
public final class DocumentFactory {
   XDocument document;
   XDocument getDocument(String type){
   if(type.equals("text"){
      document = new TextDocument();
   }
   else if(type.equals("sheet"){
      document = new SpreadSheet();
   }
   return document;
   }
}

public interface XDocument{
   open();
}

public class TextDocument implements XDocument{
   //concrete class for Text documents
   open(){
      //method to open text document
      System.out.println("opening a text document...");
   }
}

public class SpreadSheet implements XDocument{
  //concrete class for spreadsheet documents
  open(){
     //method to open spreadsheet document
     System.out.println("opening a spreadsheet document...");
  }
}

class DocumentProgram{
   public static void main(String[] args){
      XDocument doc = df.getDocument("text");  //this just created an instance of TextDocument without knowing its class name.
      doc.open();
   }
}

Singleton Pattern

In Singleton Pattern, the class can only create a single instance. We want a class to have only a single instance for various reasons. Sometimes, we want use a global object to keep information about your program. This object should not have any copies. This information might be things like configuration of the program, or a master object that manages pools of resources. So when you need a resource, you ask the master object to get it for you. Now if there were many copies of this master object, you would not know whom to ask for that resource. This single object should not be allowed to have copies. Singleton Pattern forces this rule so that programmer doesn't have to remember about not creating copies. Singleton pattern will create an instance if it doesn't exist and will not create any new instance if an instance already exist. It will just return a reference to that single instance. 

class ProgramConfiguration{
    public ProgramConfiguraiton(){
        //default constructor code
    }
}

A new instance of a class is created by the constructor. Most of the time, we have a public constructor, which is called to create a new instance. Since we want to prohibit multiple instance, we have to restrict access to the constructor. This is done by making the constructor private. 

class ProgramConfiguration{
    private ProgramConfiguration(){
        //default private constructor code
    }
}

then we create a static public method that will make sure that only one instance lives in the whole program. 

class ProgramConfiguration{
    private static ProgramConfiguration _configObject;
    private ProgramConfiguration(){
        //default private constructor code
    }
    public getInstance(){
        /*
        if an instance exist return that instance otherwise 
        call the constructor to create an instance and return it.
        */
        if(_configObject = null){
        _configObject = ProgramConfiguration();
        }
        return _configObject;
    }
}

So anytime you want to get that single object, you call the getInstance() method. 

main(){
    /*
    no access to default constructor. so if you did 
    ProgramConfiguration pc = new ProgramConfiguration(); 
    you will get compilation error.
    */
    ProgramConfiguration pc = ProgramConfiguration.getInstance();
    ProgramConfiguration newpc = ProgramConfiguration.getInstance();
    /*
    in the above code pc and newpc both point to the same static object. when 
    getinstance() is called for the second time, it finds that _configObject is not null 
    anymore, so it doesn't call the constructor to create any new instance.
    */
}
