BEGINNER TOPIC Polymorphism When the implementation for the same member signature varies between two or more classes, you have a key object-oriented principle: polymorphism Poly meaning many and morph meaning form, polymorphism refers to the fact that there are multiple implementations of the same signature And since the same signature cannot be used multiple times within a single class, each implementation of the member signature occurs on a different class The idea behind polymorphism is that the object itself knows best how to perform a particular operation, and by enforcing common ways to invoke those operations, polymorphism is also a technique for encouraging code reuse when taking advantages of the commonalities Given multiple types of documents, each document type class knows best how to perform a Print() method for its corresponding document type Therefore, instead of defining a single print method that includes a switch statement with the special logic to print each document type, with polymorphism you call the Print() method corresponding to the specific type of document you wish to print For example, calling Print() on a word processing document class behaves according to word processing specifics, and calling the same method on a graphics document class will result in print behavior specific to the graphic Given the document types, however, all you have to do to print a document is to call Print(), regardless of the type Moving the custom print implementation out of a switch statement offers several maintenance advantages First, the implementation appears

in the context of each document type s class rather than in a location far removed; this is in keeping with encapsulation Second, adding a new document type doesn t require a change to the switch statement Instead, all that is necessary is for the new document type class to implement the Print() signature Abstract members are intended to be a way to enable polymorphism The base class specifies the signature of the method and the derived class provides implementation (see Listing 620)

class DelegateSample { // public static void BubbleSort( int[] items, GreaterThanHandler greaterThan) { int i; int j; int temp; for (i = itemsLength - 1; i >= 0; i--) { for (j = 1; j <= i; j++) { if (greaterThan(items[j - 1], items[j])) { temp = items[j - 1]; items[j - 1] = items[j]; items[j] = temp; } } } } // }

public class Program { public static void Main() { PdaItem[] pda = new PdaItem[3]; Contact contact = new Contact("Sherlock Holmes"); contactAddress = "221B Baker Street, London, England"; pda[0] = contact; Appointment appointment = new Appointment("Soccer tournament"); appointmentStartDateTime = new DateTime(2008, 7, 18); appointmentEndDateTime = new DateTime(2008, 7, 19); appointmentLocation = "Est dio da Machava"; pda[1] = appointment; contact = new Contact("Anne Frank"); contactAddress = "263 Prinsengracht, Amsterdam, Netherlands"; pda[2] = contact; List(pda); } public static void List(PdaItem[] items) { // Implemented using polymorphism The derived // type knows the specifics of implementing // GetSummary() foreach (PdaItem item in items) { ConsoleWriteLine("_________________");

GreaterThanHandler is a data type that represents a method for comparing two integers Within the BubbleSort() method you then use the instance of the GreaterThanHandler , called greaterThan, inside the conditional expression Since greaterThan represents a method, the syntax to invoke the method is identical to calling the method directly In this case, greaterThan takes two integer parameters and

ConsoleWriteLine(itemGetSummary()); } } }

returns a Boolean value that indicates whether the first integer is greater than the second one Perhaps more noteworthy than the particular algorithm, the GreaterThanHandler delegate is strongly typed to return a bool and to accept only two integer parameters Just as with any other method, the call to a delegate is strongly typed, and if the data types don't match up, then the C# compiler reports an error Let's consider how the delegate works internally

________ FirstName: Sherlock LastName: Holmes Address: 221B Baker Street, London, England ________ Subject: Soccer tournament Start: 7/18/2008 12:00:00 AM End: 7/19/2008 12:00:00 AM Location: Esta dio da Machava ________ FirstName: Anne LastName: Frank Address: 263 Prinsengracht, Amsterdam, Netherlands

In this way, you can call the method on the base class but the implementation is specific to the derived class

C# defines all delegates, including GreaterThanHandler , as derived indirectly from SystemDelegate, as shown in Figure 131

Given any class, whether a custom class or one built into the system, the methods shown in Table 62 will be defined
