## org.springframework.beans.factory.support
Class SimpleInstantiationStrategy

    java.lang.Object
      org.springframework.beans.factory.support.SimpleInstantiationStrategy

All Implemented Interfaces:
  InstantiationStrategy

Direct Known Subclasses:
  CglibSubclassingInstantiationStrategy

    public class SimpleInstantiationStrategy

extends Object
implements InstantiationStrategy

Simple object instantiation strategy for use in a BeanFactory.

Does not support Method Injection, although it provides hooks for subclasses to override to add Method Injection support, for example by overriding methods.

Since:
  1.1
Author:
  Rod Johnson, Juergen Hoeller

Constructor Summary
`SimpleInstantiationStrategy()`

Method Summary
`static Method` | `getCurrentlyInvokedFactoryMethod()` Return the factory method currently being invoked or `null` if none.
`Object` | `instantiate(RootBeanDefinition beanDefinition, String beanName, BeanFactory owner)` Return an instance of the bean with the given name in this factory.
`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.
`Object` | `instantiate(RootBeanDefinition beanDefinition, String beanName, BeanFactory owner, Object factoryBean, Method factoryMethod, Object[] args)` Return an instance of the bean with the given name in this factory, creating it via the given factory method.
`protected Object` | `instantiateWithMethodInjection(RootBeanDefinition beanDefinition, String beanName, BeanFactory owner)` Subclasses can override this method, which is implemented to throw UnsupportedOperationException, if they can instantiate an object with the Method Injection specified in the given RootBeanDefinition.
`protected Object` | `instantiateWithMethodInjection(RootBeanDefinition beanDefinition, String beanName, BeanFactory owner, Constructor ctor, Object[] args)` Subclasses can override this method, which is implemented to throw UnsupportedOperationException, if they can instantiate an object with the Method Injection specified in the given RootBeanDefinition.

Method Detail

### instantiate

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

  Description copied from interface: `InstantiationStrategy`
  Return an instance of the bean with the given name in this factory.

  Specified by:
    `instantiate` in interface `InstantiationStrategy`
  Parameters:
    `beanDefinition` - the bean definition
    `beanName` - name of the bean when it's created in this context. The name can be `null` if we're autowiring a bean that doesn't belong to the factory.
    `owner` - owning BeanFactory
  Returns:
    a bean instance for this bean definition

### instantiateWithMethodInjection

    protected Object instantiateWithMethodInjection(RootBeanDefinition beanDefinition,
                                                    String beanName,
                                                    BeanFactory owner)

  Subclasses can override this method, which is implemented to throw UnsupportedOperationException, if they can instantiate an object with the Method Injection specified in the given RootBeanDefinition. Instantiation should use a no-arg constructor.

### instantiate

    public Object instantiate(RootBeanDefinition beanDefinition,
                              String beanName,
                              BeanFactory owner,
                              Constructor<?> ctor,
                              Object[] args)

  Description copied from interface: `InstantiationStrategy`
  Return an instance of the bean with the given name in this factory, creating it via the given constructor.

  Specified by:
    `instantiate` in interface `InstantiationStrategy`
  Parameters:
    `beanDefinition` - the bean definition
    `beanName` - name of the bean when it's created in this context. The name can be `null` if we're autowiring a bean that doesn't belong to the factory.
    `owner` - owning BeanFactory
    `ctor` - the constructor to use
    `args` - the constructor arguments to apply
  Returns:
    a bean instance for this bean definition

### instantiateWithMethodInjection

    protected Object instantiateWithMethodInjection(RootBeanDefinition beanDefinition,
                                                    String beanName,
                                                    BeanFactory owner,
                                                    Constructor ctor,
                                                    Object[] args)

  Subclasses can override this method, which is implemented to throw UnsupportedOperationException, if they can instantiate an object with the Method Injection specified in the given RootBeanDefinition. Instantiation should use the given constructor and parameters.

### instantiate

    public Object instantiate(RootBeanDefinition beanDefinition,
                              String beanName,
                              BeanFactory owner,
                              Object factoryBean,
                              Method factoryMethod,
                              Object[] args)

  Description copied from interface: `InstantiationStrategy`
  Return an instance of the bean with the given name in this factory, creating it via the given factory method.

  Specified by:
    `instantiate` in interface `InstantiationStrategy`
  Parameters:
    `beanDefinition` - bean definition
    `beanName` - name of the bean when it's created in this context. The name can be `null` if we're autowiring a bean that doesn't belong to the factory.
    `owner` - owning BeanFactory
    `factoryBean` - the factory bean instance to call the factory method on, or `null` in case of a static factory method
    `factoryMethod` - the factory method to use
    `args` - the factory method arguments to apply
  Returns:
    a bean instance for this bean definition

### getCurrentlyInvokedFactoryMethod

    public static Method getCurrentlyInvokedFactoryMethod()

  Return the factory method currently being invoked or `null` if none. Allows factory method implementations to determine whether the current caller is the container itself as opposed to user code.
