  2. Formal concept analysis - Wikipedia

    en.wikipedia.org/wiki/Formal_concept_analysis

    In information science, formal concept analysis (FCA) is a principled way of deriving a concept hierarchy or formal ontology from a collection of objects and their properties. Each concept in the hierarchy represents the objects sharing some set of properties; and each sub-concept in the hierarchy represents a subset of the objects (as well as ...

  3. Method chaining - Wikipedia

    en.wikipedia.org/wiki/Method_chaining

    Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.

  4. Chaining - Wikipedia

    en.wikipedia.org/wiki/Chaining

    A behavior chain is a sequence of behaviors that happen in a particular order where the outcome of the previous step in the chain serves as a signal to begin the next step in the chain. In terms of behavior analysis, a behavior chain is begun with a discriminative stimulus (SD) which sets the occasion for a behavior, the outcome of that ...

  5. Fluent interface - Wikipedia

    en.wikipedia.org/wiki/Fluent_interface

    A fluent interface is normally implemented by using method chaining to implement method cascading (in languages that do not natively support cascading), concretely by having each method return the object to which it is attached [citation needed], often referred to as this or self.

  6. Object-oriented analysis and design - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_analysis...

    Object-oriented design is the discipline of defining the objects and their interactions to solve a problem that was identified and documented during object-oriented analysis. What follows is a description of the class-based subset of object-oriented design, which does not include object prototype-based approaches where objects are not typically ...

    en.wikipedia.org/wiki/Semiotic_theory_of_Charles...

    An object (or semiotic object) is a subject matter of a sign and an interpretant. It can be anything discussable or thinkable, a thing, event, relationship, quality, law, argument, etc., and can even be fictional, for instance Hamlet. [20] All of those are special or partial objects.

  8. Chain-of-responsibility pattern - Wikipedia

    en.wikipedia.org/wiki/Chain-of-responsibility...

    In object-oriented design, the chain-of-responsibility pattern is a behavioral design pattern consisting of a source of command objects and a series of processing objects. [1] Each processing object contains logic that defines the types of command objects that it can handle; the rest are passed to the next processing object in the chain.
