Turns domain data into HTML in two steps: first by forming some kind of logical page, then rendering the logical page into HTML
Making Barcode In Java
Using Barcode maker for Java Control to generate, create barcode image in Java applications.
If you have a Web application with many pages, you often want a consistent look and organization to the site If every page looks different, you end up with a site that users find confusing You may also want to make global changes to the appearance of the site easily, but common approaches using Template View (350) or Transform View (361) make this difficult because presentation decisions are often duplicated across multiple pages or transform modules A global change can force you to change several files
Decode Barcode In Java
Using Barcode recognizer for Java Control to read, scan read, scan image in Java applications.
Two Step View deals with this problem by splitting the transformation into two stages The first transforms the model data into a logical presentation without any specific formatting; the second converts that logical presentation with the actual formatting needed This way you can make a global change by altering the second stage, or you can support multiple output looks and feels with one second stage each
Denso QR Bar Code Creator In C#.NET
Using Barcode drawer for .NET framework Control to generate, create Quick Response Code image in Visual Studio .NET applications.
How It Works
Quick Response Code Creation In .NET
Using Barcode generator for ASP.NET Control to generate, create Quick Response Code image in ASP.NET applications.
The key to this pattern is in making the transformation to HTML a two-stage process The first stage assembles the information in a logical screen structure that is suggestive of the display elements yet contains no HTML The second stage takes that presentation-oriented structure and renders it into HTML
Generating QR Code JIS X 0510 In .NET
Using Barcode creation for .NET Control to generate, create QR-Code image in .NET applications.
This intermediate form is a kind of logical screen Its elements might include things like fields, headers, footers, tables, choices, and the like As such it's certainly presentation-oriented and certainly forces the screens to follow a definite style You can think of the presentation-oriented model as one that defines the various widgets you can have and the data they contain but doesn't specify the HTML appearance
Painting QR-Code In Visual Basic .NET
Using Barcode creation for VS .NET Control to generate, create QR-Code image in VS .NET applications.
This presentation-oriented structure is assembled by specific code written for each screen The first stage's responsibility is to access a domain-oriented model, either a database, an actual domain model, or a domainoriented Data Transfer Object (401); to extract the relevant information for that screen; and then to put that

Using Barcode encoder for Java Control to generate, create GS1 - 13 image in Java applications.
information into the presentation-oriented structure
Code39 Encoder In Java
Using Barcode generation for Java Control to generate, create USS Code 39 image in Java applications.
The second stage turns this presentation-oriented structure into HTML It knows about each element in the presentation-oriented structure and how to show it as HTML Thus, a system with many screens can be rendered as HTML by a single second stage so that all the HTML formatting decisions are made in one place Of course, the constraint is that the resulting screen must be derivable from the presentation-oriented structure
Create GS1 - 12 In Java
Using Barcode creator for Java Control to generate, create UPC Symbol image in Java applications.
There are several ways to build a Two Step View Perhaps the easiest is with two-step XSLT Single-step XSLT follows the approach in Transform View (361), in which each page has a single XSLT style sheet that transforms the domain-oriented XML into HTML In the two-step approach there are two XSLT style sheets The first-stage style sheet transforms the domain-oriented XML into presentation-oriented XML, the secondstage style sheet renders that XML into HTML
Barcode Printer In Java
Using Barcode creator for Java Control to generate, create barcode image in Java applications.
Another way is to use classes Here you define the presentation-oriented structure as a set of classes: with a table class, a row class, and so forth The first stage takes domain information and instantiates these classes into a structure that models a logical screen The second stage renders the classes into HTML, either by getting each presentation-oriented class to generate HTML for itself or by having a separate HTML renderer class to do the job
Drawing Code 128B In Java
Using Barcode generation for Java Control to generate, create Code 128A image in Java applications.
Both approaches are based on Transform View (361) You can also use a Template View (350) based approach, in which you pick templates based on the idea of a logical screen for example:
Code11 Printer In Java
Using Barcode drawer for Java Control to generate, create Code 11 image in Java applications.
<field label = "Name" value = "getName" />
Barcode Creation In Visual Basic .NET
Using Barcode generator for .NET Control to generate, create barcode image in VS .NET applications.
The template system then converts these logical tags into HTML In such a scheme the page definition includes no HTML but only these logical screen tags As a result it will probably be an XML document, which of course means that you lose the ability to use WYSIWYG HTML editors
