org.springframework.beans.factory.support.InstantiationStrategy
Known Indirect Subclasses

Class Overview

Interface responsible for creating instances corresponding to a root bean definition.

This is pulled out into a strategy as various approaches are possible, including using CGLIB to create subclasses on the fly to support Method Injection.

Summary

Public Methods
abstract Object instantiate(RootBeanDefinition beanDefinition, String beanName, BeanFactory owner)
Return an instance of the bean with the given name in this factory.
abstract Object instantiate(RootBeanDefinition beanDefinition, String beanName, BeanFactory owner, Object factoryBean, Method factoryMethod, Object[] args)

abstract Object instantiate(RootBeanDefinition beanDefinition, String beanName, BeanFactory owner, Constructor<?> ctor, Object[] args)
Return an instance of the bean with the given name in this factory, creating it via the given constructor.

Public Methods

public abstract Object instantiate (RootBeanDefinition beanDefinition, String beanName, BeanFactory owner)
