Never store objects or arrays in the prototype object, unless you want to share them across all instances. Instead, store references to objects or arrays in the constructor. This way, each instance has its own copy of the object.

See how we are adding the processes to the processor in the same order we had in our function calls previously Our process objects are logically similar to function calls, and the order in which they appear is logically similar to a program, except that they are composed at runtime rather than compile time. We can then use this configuration method in our client, and call on the processor to process our documents, as shown in Example 5-8.

static void Main(string[] args) { Document doc1 = new Document { Author = "Matthew Adams", DocumentDate = new DateTime(2000, 01, 01), Text = "Am I a year early " }; Document doc2 = new Document { Author = "Ian Griffiths", DocumentDate = new DateTime(2001, 01, 01), Text = "This is the new millennium, I promise you." };

DocumentProcessor processor = Configure(); Console.WriteLine("Processing document 1"); processor.Process(doc1); Console.WriteLine(); Console.WriteLine("Processing document 2"); processor.Process(doc2); } Console.ReadKey();

Notice in these examples that you do not use the params modifier in the invocation. The use of the modifier in parameter arrays does not fit the pattern of the other parameter types. The other parameter types are consistent, in that they either use a modifier or do not use a modifier. Value parameters take no modifier in either the declaration or the invocation. Reference and output parameters require the modifier in both places. Parameter arrays, however, Require the modifier in the declaration Do not accept it in the invocation

If you compile and run, you ll see the same output as before:

Processing document 1 Document traduit. Spellchecked document. Repaginated document. Processing document 2 Document traduit. Spellchecked document. Repaginated document.

Java IText: Modifying Existing PDF Documents - Jenkov Tutorials
May 24, 2014 · If you already have a finished PDF, and just want to add a header, footer or watermark to it, IText provides the com.itextpdf.pdf.PdfStamper class. First you read the existing document using a PdfReader , then modify it using the PdfStamper .

This is a very common pattern in object-oriented design encapsulating a method in an object and/or a process in a sequence of objects. What s nice about it is that our DocumentProcessor is now coupled only to the Document class, plus the abstract base it uses as a contract for the individual processes. It is no longer coupled to each and every one of those processes; they can vary without requiring any changes to the processor itself, because they implement the contract demanded by the abstract base class. Finally, the processing sequence (the program for the DocumentProcessor) is now the responsibility of the client app, not the processor library; so our different production teams can develop their own particular sequences (and, indeed, new processes) without having to refer back to the core team and change the document processor in any way. In fact, the only thing that is a bit of a pain about this whole approach is that we have to declare a new class every time we want to wrap up a simple method call. Wouldn t it be easier just to be able to refer to the method call directly C# provides us with a tool to do just that: the delegate.

We just wrote some code that wraps up a method call inside an object. The call itself is wrapped up in another method with a well-known signature. You can think of a delegate as solving that same sort of problem: it is an object that lets us wrap up a method call on another object (or class).

You will start by examining the form where you use separate actual parameters in the invocation. This is sometimes called the expanded form. For example, the declaration of method ListInts in the following code matches all the method invocations below it, even though they have different numbers of actual parameters. void ListInts( params int[] InputList ) { ... } ... ListInts( ListInts( ListInts( ListInts( // Method declaration

But while our DocumentProcess classes have their methods hardcoded into virtual function overrides, a delegate allows us to reference a specific function (from a given class or object instance) at runtime, then use the delegate to execute that function. So, in the same way that a variable can be considered to contain a reference to an object, a delegate can be thought to contain a reference to a function (see Figure 5-2).
