Topic: Prototype pattern


  
 Prototype pattern - Wikipedia, the free encyclopedia
A software design pattern prototype pattern is used for computer programming.
Specify the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype.
Application "hard wires" the class of object to create in each "new" expression and the creation of a factory object is inherently expensive.

 Prototype Patterns
The prototype pattern is used when creating an instance of a class is very time consuming or complex in some way.
Prototype Design Pattern helps in reducing number of classes.
The PROTOTYPE PATTERN comes under the classification of Creational Patterns.

 Design Pattern Synopses
The Composite pattern also allows the objects in the tree to be manipulated in a consistent manner, by requiring all of the objects in the tree to have a common superclass or interface.
The Strategy pattern is often used with the Null Object pattern.
The Filter pattern is a special case of the Decorator pattern, where a data source or data sink object is wrapped to add logic to the handling of a data stream.

 Elena Fanea and David Baker- Prototype
The prototype pattern is especially useful for cases where the construction and initialization of an object would be more complex or time involving than the cloning (and modification) of an existing object.
The Prototype pattern is a creational pattern in which new objects are created based on an existing prototype object.
Being a creational pattern, the prototype pattern should be used when a system is required to be independent of how its objects are created, composed and represented.

 Learn more about Design pattern (computer science) in the online encyclopedia.
A design pattern is an abstraction of a solution for a particular class of problems.
Design patterns represent the accumulated knowledge of the community of software developers of standardised solutions to recurring problems.
Design patterns solve specific design problems and make object-oriented designs more flexible and elegant, and ultimately reusable.

 Seng 443 Prototype Pattern
This pattern is useful in applications that use a graphical toolbox to create instances of subclasses that represent the objects used by an application.
This pattern allows the developer a means by which they can define an object that will help in reducing the total number of classes within the system.
However, this is sort of a prototype pattern since the class object is a 'prototype' which 'copies' itself with newInstance().

 Thomas Chau's Web Site > Course Works
The prototype pattern avoid the need to create these N subclasses by parameterize GraphicTool with the specific graphical object that is should create.
One of the benefits of using this pattern is that clients are transparent to the specific class of objects that they need to create due to the use of the generic Prototype interface.
Second, developers need to consider the extent of cloning; shallow copy using references to the prototype's data or deep copy which involves making a second copy of all the data of the underlying prototype.

 jGuru: Where can I find good examples of the Prototype pattern?
Recall that the idea of prototype is that you are passed an object and use that object as a template to create a new object.
The Factory Pattern is very different from a Prototype, A Prototype gets used only in case where you need to do cloning of the same object and may want try out different operation, A Factory Pattern moves the object creation required by a class to its sub class.
Thank you for explaing prototype but the only thing which I did n't under stand why do I need to clone why cant the original object be sent.

 Felix User Guide - Assign User Interface
The prototype patterns are the generally rough spin systems that are the results of automated spin system detection algorithms.
If the selected prototype pattern is a triple resonance spin system with frequencies from the neighboring spin system, that information is lost during this promotion--that is, this information is not transferred to neighbor probability, which is different from the way the Assign/Promote Prototype Patterns command works.
Specifies the maximum number of frequencies of the particular patterns to use in the detection algorithm.

 Pattern Summaries: Prototype
Generalizing this, the Prototype pattern enables a class to create objects that implement a known interface by giving it a prototypical instance of each kind of object it will create.
The code example for this pattern is based on a different scenario.
A complete pattern will also provide reasons to use and not use the solution, the consequences of using the solution and suggestions on how to implement the solution.

 Technoblog: Classes are Just a Prototype Pattern
Once you see it this way, you will notice that having classes at all is a crutch… an unnecessary layer that doesn’t add to object-oriented programming… in fact it makes things more confusing to have the separation at times.
An instance has a reference to a class in it, and a class has a reference to its superclass.
I have been thinking a lot about prototyped versus class-based languages lately and once I really understood it, I fell in love.

The Decorator pattern allows us to "sepcity the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype." [GoF,1995] The Prototype pattern is one of the object creational patterns.
It can be especially used in such situations that objects can be created dynamically.
[GoF,1995] This patterns helps in avoiding building classes of tools for every class of product.

This pattern creates an original instance to act as a model for a type of object and copies itself, the instance, to form new objects.
   When it is time to create on of the objects dynamically, you copy or clone the object from the prototype and modify it.
  If you have multiple subclasses only differ in the objects they create, you could instead clone a prototype of them.
