Apple Inc., formerly Apple Computer, Inc., is an American multinational corporation headquartered in Cupertino, California, that designs, develops, and sells consumer electronics, computer software and personal computers.
The highest frequency signal that can be faithfully recorded for a given sampling rate. Attempts to sample a signal containing higher frequencies results in the generation of an alias signal below the Nyquist frequency. The Nyquist frequency is half the sampling rate. See also visual context.
Industry:Software; Computer
(1) In object-oriented programming, a programming unit that groups together a data structure (fields) and the operations (methods) that can use or affect that data. Objects are the principal building blocks of object-oriented programs. (2) In Mach, a collection of data, with permissions and ownership. (3) In AppleScript, an instantiation of a class definition, which can include properties and actions. (4) A group of bright, high-intensity pixels in an image, as opposed to the darker pixels, which are considered part of the background.
Industry:Software; Computer
In AppleScript, the hierarchy of objects in a running application. AppleScript and Cocoa scripting depend on the object containment hierarchy to locate the objects on which to perform an operation. See also AppleScript object model.
Industry:Software; Computer
A file containing executable code and data. Object files in the Mach-O executable format take the suffix.oand are the product of compilation using the GNU compiler ( gcc ). Multiple object files are typically linked together along with required frameworks to create a program. See also code fragment, dynamic linking.
Industry:Software; Computer
In AppleScript, a command that invokes a specified method of each specified receiver. With an object-first command, objects perform the specified action on themselves. Compare verb-first command.
Industry:Software; Computer
In WebObjects, the graph of objects (especially enterprise object instances) that are contained by EOEditingContext objects.
Industry:Software; Computer
In WebObjects, a system for transforming Entity-Relationship models to an object-oriented programming framework. Enterprise Objects performs object-relational mapping (mapping database structures to Java objects) with the help of Entity-Relationship models called EOModels. See also Entity-Relationship modeling.
Industry:Software; Computer
An object-oriented programming language based on standard C and a runtime system that implements the dynamic functions of the language. The few Objective-C extensions to the C language are mostly based on Smalltalk, one of the first object-oriented programming languages. Objective-C is available in the Cocoa application environment.
Industry:Software; Computer
In AppleScript, a phrase that specifies the information needed to find another object in terms of the objects in which it is contained. Cocoa scripting makes use of object specifiers to find objects in your application while executing a script command and to return information requested by a script. See also absolute object specifier, object containment hierarchy, relative object specifier, reference form.
