The builder mode is to build a product according to a specified blueprint, and its main purpose is to generate a new product by assembling parts. Using the abstract factory pattern does not need to care about the construction process, but only cares about which products are produced by which factories.
#PRODUCT BUILDER JAVA SERIES#
A product family is a series of products: product combinations with different classification dimensions. The abstract factory pattern is the creation of a product family. Abstract Factory Pattern vs Builder Pattern.The builder pattern is not suitable if there are large differences between products.

Adding new concrete builders does not require modifying the original code.Use different concrete builders to get different product objects.Breaking down the steps of creating complex products into different methods makes the creation process clearer.The client does not need to know the details of the internal composition of the product, and the product itself is decoupled from the product creation process, so that the same creation process can create different product objects.Complete building the house, return to the product (high-rise) Complete building the house, return the product (ordinary house) HouseDirector houseDirector = new HouseDirector(commonHouse) prepare to create the conductor of the house This is part one of using Criteria Builder (package javax.persistence). So its about time I learn the power of writing complex queries in a way that, for example, in a refactoring situation I dont need to change strings in my queries. Director (commander): Build an object using the Builder interface, responsible for controlling the production process of the product object, isolating the production process of the customer and the object. Looking online on the timeline of this, it appears to be available since Java Persistence 2.0.

ConcreteBuilder (concrete builder): implements the interface, builds and assembles the various components.Builder (abstract builder): Creates a specified interface/abstract class for each component of a product object.It can abstract the construction process of complex objects (abstract category), so that different implementation methods of this abstract process can construct objects with different performance (attributes).Ĭreates a complex object step-by-step, allowing users to build complex objects just by specifying their type and content, without needing to know the specific construction details inside. The Builder Pattern, also known as the Builder Pattern, is an object construction pattern. The program is not easy to expand and maintain, and the product and the process of creating the product are encapsulated together, and the coupling is high.ĭecoupling the product and creating the product process = 'Builder pattern'
