Amplifier Design in Software

Build GTIN - 12 in Software Amplifier Design

In this example, MyEventArgs is derived from EventArgs. MyEventArgs adds just one field of its own: EventNum. The event handler delegate MyEventHandler now takes the two parameters required by the .NET Framework. As explained, the first is an object reference to the generator of the event. The second is a reference to EventArgs or a class derived from EventArgs. The event handlers in the X and Y classes, Handler( ), also have the same types of parameters. Inside MyEvent, a MyEventHandler called SomeEvent is declared. In the OnSomeEvent( ) method, SomeEvent is called with the first argument being this, and the second argument being a MyEventArgs instance. Thus, the proper arguments are passed to MyEventHandler to fulfill the requirements for .NET compatibility.

In doing engine programming, it s essential to think in a logical and structured way. When working with systems that could potentially be used on multiple game projects, they need to be designed in a logical way. Otherwise, you can end up making people jump through more hoops than necessary. Dave Bryson, Engine Programmer, Electronic Arts UK

// Use an anonymous type to improve the join demo program. using System; using System.Linq; // A class that links an item name with its number. class Item { public string Name { get; set; } public int ItemNumber { get; set; } public Item(string n, int inum) { Name = n; ItemNumber = inum; } } // A class that links an item number with its in-stock status. class InStockStatus { public int ItemNumber { get; set; } public bool InStock { get; set; } public InStockStatus(int n, bool b) { ItemNumber = n; InStock = b; } } class AnonTypeDemo { static void Main() { Item[] items = { new Item("Pliers", 1424), new Item("Hammer", 7892), new Item("Wrench", 8534), new Item("Saw", 6411) };

This version of FailSoftArray works the same as the previous version, but it does not contain the explicitly declared backing fields. Here are some restrictions that apply to using access modifiers with accessors. First, only the set or get accessor can be modified, not both. Furthermore, the access modifier must be more restrictive than the access level of the property or indexer. Finally, an access modifier cannot be used when declaring an accessor within an interface or when implementing an accessor specified by an interface. (Interfaces are described in 12.)

Plasma membrane The cell membrane. Polar bond A covalent bond in which one or more electrons are shared unevenly, so that the electric charge is not evenly distributed across the bond. The result is that one atom has a partial positive charge and one atom has a partial negative charge. Polarizability For an induced dipole, the ratio of the dipole moment to the electric field strength. Polymer A large molecule made by connecting together many smaller molecules. See also residue. Polypeptide A polymer of amino acids; a protein. Polysaccharide A carbohydrate polymer containing more than 20 monosaccharides. (See also oligosaccharide.) Polyunsaturated fatty acid A fatty acid with two or more double bonds in the hydrocarbon chain. Preparative technique A technique used to purify or isolate biological specimens (organisms, cells, or molecules) or otherwise get them ready for use in some other process or further experimentation. Primary active transport An active transport where the energy needed for transport comes from a simultaneous reaction cleaving a high-energy phosphate bond. Primary amine An amine where two of the three covalent bonds are to hydrogen, while the third atom is to a carbon atom, linking the amine group to the rest of the molecule. Primary structure The specific atoms or groups of atoms making up a molecule and the order in which they are connected to one another. Primary structure says nothing about the shape of a molecule, only which atoms the molecule is made of and which atoms are connected to each other and in what order. Prokaryote An organism that has prokaryotic cells. Prokaryotic The quality of not having a cell nucleus. Protein A polymer of amino acids. Purine A class of nucleotide base with two rings: one is a five-atom ring with two nitrogen atoms, and the other a six-atom pyrimidine ring. The purine s two rings are covalently attached to one another in a way such that they share two carbon atoms.
