In the Builder Pattern a director and a builder work together to build an object. The director controls the building and specifies what parts and variations will go into an object. The builder knows how to assemble the object given …

The functionality used in Delphi's VCL to create forms and components is similar in concept to the builder. Delphi creates forms using a common interface, through Application.CreateForm and through the TForm class constructor. TForm implements a common constructor using the …

Example of "Builder" desnig pattern in Python

"""
Separate the construction of a complex object from its representation so
that the same construction process can create different representations.
"""

Discussion. The forte of Builder is constructing a complex object step by step. An abstract base class declares the standard construction process, and concrete derived classes define the appropriate implementation for each step of the process. In this example, "distributed …

Example of "Builder" design pattern in Java

/* "Product" */
class Pizza {
    private String dough = "";
    private String sauce = "";
    private String topping = "";
 
    public void setDough(String dough) {
        this.dough = dough;
    }
 
    public void setSauce(String …

The reasons

• Separating the construction of a complex object from its representation so that the same construction process can create different representations.
• Dismantling a complex representation, creating one goal from several variations.

Problems

Separation of the object interpretation algorithm (for …
