Proxy pattern
E679871
The Proxy pattern is a structural design pattern in software engineering that provides a surrogate or placeholder object to control access to another object, often adding lazy initialization, access control, logging, or remote communication.

How this entity was disambiguated
This entity first appeared as the object of triple T7665427 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A.
Factory Method
Factory Method is a creational design pattern that defines an interface for creating objects while allowing subclasses to decide which concrete classes to instantiate, promoting loose coupling and extensibility.
-
B.
Template Method
Template Method is a behavioral design pattern that defines the skeleton of an algorithm in a base class while allowing subclasses to override specific steps without changing the algorithm’s overall structure.

Prototype
Prototype is a creational design pattern that enables cloning existing objects to create new instances instead of instantiating classes directly.
- F. None of above. chosen

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Proxy pattern Description of subject: The Proxy pattern is a structural design pattern in software engineering that provides a surrogate or placeholder object to control access to another object, often adding lazy initialization, access control, logging, or remote communication.
