foreach( $_SERVER['argv'] as $arg ) { if ( strpos( $arg, '=' ) ) { list( $key, $val )=explode( "=", $arg ); $this->setProperty( $key, $val ); } } } function getProperty( $key ) { if ( isset( $this->properties[$key] ) ) { return $this->properties[$key]; } } function setProperty( $key, $val ) { $this->properties[$key] = $val; } function addFeedback( $msg ) { array_push( $this->feedback, $msg ); } function getFeedback( ) { return $this->feedback; } function getFeedbackString( $separator="\n" ) { return implode( $separator, $this->feedback ); } } As you can see, most of this class is taken up with mechanisms for setting and acquiring properties. The init() method is responsible for populating the private $properties array. Notice that it works with command line arguments as well as the HTTP requests. This is extremely useful when it comes to testing and debugging. Once you have a Request object, you should be able to access an HTTP parameter via the getProperty() method, which accepts a key string and returns the corresponding value (as stored in the $properties array). You can also add data via setProperty(). The class also manages a $feedback array. This is a simple conduit through which controller classes can pass messages to the user. A Command You have already seen the Command base class, and 11 covered the Command pattern in detail, so there s no need to go too deep into Commands. Let s round things off, though, with a simple concrete Command object:

Two ways to convert to bool The bool datatype is privileged, in that the loop and conditional statements of 6 expect a bool value. In simple situations like a collection that is always either true or false, populated or empty, you would overload public static implicit operator bool. However, there are more complex situations, such as a SqlBoolean (or a bool , in 2.0), that can be true, false, or null (not set), or perhaps a fuzzy logic type where a value from 0.4 to 0.6 might be a maybe neither true nor false. In these rare, more complex situations, you can use the infix syntax to overload the true and false operators.19 public static bool operator true(EnclosingType T) public static bool operator false(EnclosingType T) Implicit and explicit casts like bool B = Queue or bool B = (bool) Queue require a cast operator that returns a bool. Conversion in a boolean context like if (Queue) {}) can use either a cast operator or a true operator; if you define both a cast operator and a true operator, a boolean context will use the cast operator. In addition, if you define & and | operators, the compiler will use the true and false operators to evaluate expressions like if (Queue && ThreadPool) {}. This is a very specialized subject if you really need to create a new ambiguous boolean type, play with the 7\TrueFalse project, and see for yourself how commenting out the cast, &, and | operators affects the evaluation of various boolean expressions.

Simpler syntax than in Delphi Since C# does not separate declaration from implementation the way Delphi does, nested types have a simpler syntax than in Delphi. Syntactically, a nested type is just another member of the class, enclosed in curlies like a method body. For example,

Have you ever seen your code grounded because it is just too hard to install This is especially true for projects that are developed in place Such projects settle into their context, with passwords and directories, databases and helper application invocations programmed right into the code Deploying a project of this kind can be a major undertaking, with teams of programmers picking through source code to amend settings so that they fit the new environment This problem can be eased to some degree by providing a centralized configuration file or class so that settings can be changed in one place, but even then installation can be a chore The difficulty or ease of installation will have a major impact upon the popularity of any application you distribute It will also impede or encourage multiple and frequent deployment during development As with any repetitive and time-consuming task, installation should be automated.
