Object identity

A requesthandling mechanism that selects a method based on the type of target object. This allows the specification of one request that can result in invocation of different methods depending on the type of the target object. Most objectoriented languages support the selection of the appropriate method based on the class of the object (classical polymorphism). A few languages or systems support characteristics of the object, including values and userdefined defaults (generalized polymorphism). Having many forms. In the context of object-oriented programming terminology and concepts, the characteristic of an object to provide different behaviors based on the same message and methods owing to variances in external conditions.

A technology that uses electromagnetic or electrostatic coupling in the radio frequency (RF) portion of the electromagnetic spectrum to identify a specific device. Each RFID tag includes a unique identifier, so that when a nearby antenna/transceiver actives the tag, it transmits that identifier back to the antenna where that value is recorded or used to trigger some kind of action. For example, most modern toll-road systems use RFID devices that drivers attach to the windshield of their car, and each time a device is “read” by an antenna, the vehicle owner’s toll balance is incremented by the cost of that transit. RFID devices may also be used to track individuals (carrying tags), equipment (bearing tags), and so forth, within the premises of an enterprise for security monitoring.

Any method, language, or system that supports object identity, classification, and encapsulation and specialization. C++, Smalltalk, ObjectiveC, and Eiffel are examples of objectoriented implementation languages.

A platform-independent programming language developed by Sun Microsystems. Objectoriented programming language developed at Sun Microsystems to solve a number of problems in modern programming practice. The Java language is used extensively on the World Wide Web, particularly for applets.
