The Builder Pattern

The builder pattern is used to separate the configuration of an object from its creation. The calling component has the configuration data and passes it to an intermediary—the builder—that is responsible for creating an object on behalf of the component. This separation can reduce the amount of knowledge that the calling component has about the objects it uses and concentrates default configuration values in the builder class, rather than being required in every component that creates objects. Table 11-1 puts the builder pattern in context.
