7. Functions

Slice ePub May 29, 2014

A function is a block of JavaScript code that is defined once but may be executed, or invoked, any number of times. You may already be familiar with the concept of a function under a name such as subroutine or procedure. JavaScript functions are parameterized: a function definition may include a list of identifiers, known as parameters, that work as local variables for the body of the function. Function invocations provide values, or arguments, for the functions parameters. Functions often use their argument values to compute a return value that becomes the value of the function-invocation expression. In addition to the arguments, each invocation has another valuethe invocation contextthat is the value of the this keyword.

If a function is assigned to the property of an object, it is known as a method of that object. When a function is invoked on or through an object, that object is the invocation context or this value for the function. Functions designed to initialize a newly created object are called constructors. Constructors were described in Creating Objects and will be covered again in Chapter8.

7. Networking, Remoting, and Web Services

Slice ePub June 04, 2015

Computing in the 21st century is all about networking. While a disconnected computer can still be useful for word processing, spreadsheets, and single-player games, a connected computer opens up the world of email, the World Wide Web, and multiplayer games.

Mono gives you access to all the common networking technologies from the hackneyed TCP/IP sockets to higher-level protocols such as HTTP and SOAP, and de facto standards like XML-RPC, as well as database access.

In this chapter, you’ll see how Mono lets you use networking technologies to connect to remote computers, call remote procedures, and access databases.

It used to be that running ASP.NET required a large investment in software. The Microsoft web application framework requires the Internet Information Services (IIS) that comes with Windows. The Windows End User License Agreement limits how many users may be served from a Windows workstation install, so that means you might need to install Microsoft Windows Server.

5. Metadata Queries

Source: SQL Cookbook
Slice ePub June 01, 2015

This chapter presents recipes that allow you to find information about a given schema. For example, you may wish to know what tables you’ve created or which foreign keys are not indexed. All of the RDBMSs in this book provide tables and views for obtaining such data. The recipes in this chapter will get you started on gleaning information from those tables and views. There is, however, far more information available than the recipes in this chapter can show. Consult your RDBMSs documentation for the complete list of catalog or data dictionary tables/views.

For purposes of demonstration, all the recipes in this chapter assume the schema name SMEAGOL.

You want to see a list all the tables you’ve created in a given schema.

The solutions that follow all assume you are working with the SMEAGOL schema. The basic approach to a solution is the same for all RDBMSs: you query a system table (or view) containing a row for each table in the database.

8 Eclogues Between the Truculent

Slice PDF May 12, 2015


Derek Mahon

I met Louis MacNeice twice if you can call it that, and both times he was in rugby mode. Calling one afternoon at the flat in Regent’s Park he shared with the actress Mary Wimbush, we found him watching rugby on TV and saying little. Constrained by his rugby-watching silence, I said little myself. What did I expect, poetry talk? (A big fan,

I had recently read his latest collection Solstices, which I thought was disappointing; this must have been 1962.) We watched some rugby and then it was time to go. I got the impression that, even without the rugby, he would have been uncommunicative. The curtains were closed and I saw only a grave grey head and a sombre equine face; though literally long in the tooth, he had ‘presence’. I was virtually ignored but didn’t mind, aware that, while to me he was the great poet, to him I was nobody in particular.

Grand houses in Regent’s Park were not my usual ambience. I was much struck by this one, by the elegant Mary Wimbush, and by the voices. Louis was nasal Oxford, a sonorous growl, Mary pure BBC circa 1960; those there of my own age had already adopted
