a notation for a list of propositions characterizing each member of the set as possible and denoting an instance, ¶5-1-4, cf. existential operator. I. i. d. contrasts with generalization (conjunctive) and instantiation (exclusive disjunction). (See also ¶4-5-2 and ¶5-5-3.)
The creation of a single instance, or implementation, of an object from an interface. The interface defines an object's methods and the number and types of its attributes. When you create an object from an interface, which acts like a template, the object has real data values. For example, a database table definition is analogous to an interface, and a row of data in the table is analogous to an object.
(1) (n.) In the XGLTM library, the allocation of resources that occurs when a variable of an object type is declared.(2) (n.) The process of creating a particular widget from a particular widget class. See also widget instance.
This is the general process of creating instances of objects and relationships during the actual execution of the application. Objects must be instantiated in order for other object to interact with them. Relationships must be instantiated prior to navigating them for collaborations. While instantiation of relationship is explicit in OOA/D, it is often implied during OOP because of the way OOPLs hide the implementation of common OO constructs. Quite commonly the rules and policies for instantiation are quite different than those for collaboration. (See category on relationships.)
In programming, instantiation is the creation of a real instance or particular realization of an abstraction or template such as a class of objects or a computer process. 1) In approaches to data modeling and programming prior to object-oriented programming, one usage of instantiate was to make a real (data-filled) object from an abstract object as you would do by creating an entry in a database table (which, when empty, can be thought of as a kind of class template for the objects to be filled in) 2) In the object-oriented programming language, Java, the object that you instantiate from a class is, confusingly enough, called a class instead of an object. In other words, using Java, you instantiate a class to create a specific class that is also an executable file you can run in a computer.
Making a copy of a default rule at an object level. This makes the object the owner of the copy of the rule. Oracle Expert uses an object's values for instantiated rules during an analysis. See also default rules and rules.
