public class RootBeanDefinition
extends AbstractBeanDefinition

Root bean definitions are the most common type of bean definition. They do not derive from a parent bean definition, and usually have a class plus optionally constructor argument values and property values.

Note that root bean definitions do not have to specify a bean class: This can be useful for deriving childs from such definitions, each with its own bean class but inheriting common property values and other settings.

Constructor Detail

RootBeanDefinition

public RootBeanDefinition()
Create a new RootBeanDefinition, to be configured through its bean properties and configuration methods.

See Also:
AbstractBeanDefinition.setBeanClass(java.lang.Class), AbstractBeanDefinition.setBeanClassName(java.lang.String), AbstractBeanDefinition.setSingleton(boolean), AbstractBeanDefinition.setAutowireMode(int), AbstractBeanDefinition.setDependencyCheck(int), AbstractBeanDefinition.setConstructorArgumentValues(org.springframework.beans.factory.config.ConstructorArgumentValues), AbstractBeanDefinition.setPropertyValues(org.springframework.beans.MutablePropertyValues)

RootBeanDefinition

public RootBeanDefinition(Class beanClass)
Create a new RootBeanDefinition for a singleton.

Parameters:
beanClass - the class of the bean to instantiate

RootBeanDefinition

public RootBeanDefinition(Class beanClass,
                          boolean singleton)
Create a new RootBeanDefinition with the given singleton status.

Parameters:
beanClass - the class of the bean to instantiate
singleton - the singleton status of the bean

RootBeanDefinition

public RootBeanDefinition(Class beanClass,
                          int autowireMode)
Create a new RootBeanDefinition for a singleton, using the given autowire mode.

Parameters:
beanClass - the class of the bean to instantiate
autowireMode - by name or type, using the constants in this interface

RootBeanDefinition

public RootBeanDefinition(Class beanClass,
                          int autowireMode,
                          boolean dependencyCheck)
Create a new RootBeanDefinition for a singleton, using the given autowire mode.

Parameters:
beanClass - the class of the bean to instantiate
autowireMode - by name or type, using the constants in this interface
dependencyCheck - whether to perform a dependency check for objects (not applicable to autowiring a constructor, thus ignored there)

RootBeanDefinition

public RootBeanDefinition(Class beanClass,
                          MutablePropertyValues pvs)
Create a new RootBeanDefinition for a singleton, providing property values.

Parameters:
beanClass - the class of the bean to instantiate
pvs - the property values to apply

RootBeanDefinition

public RootBeanDefinition(Class beanClass,
                          MutablePropertyValues pvs,
                          boolean singleton)
Create a new RootBeanDefinition with the given singleton status, providing property values.

Parameters:
beanClass - the class of the bean to instantiate
pvs - the property values to apply
singleton - the singleton status of the bean

RootBeanDefinition

public RootBeanDefinition(Class beanClass,
                          ConstructorArgumentValues cargs,
                          MutablePropertyValues pvs)
Create a new RootBeanDefinition for a singleton, providing constructor arguments and property values.

Parameters:
beanClass - the class of the bean to instantiate
cargs - the constructor argument values to apply
pvs - the property values to apply

RootBeanDefinition

public RootBeanDefinition(String beanClassName,
                          ConstructorArgumentValues cargs,
                          MutablePropertyValues pvs)
Create a new RootBeanDefinition for a singleton, providing constructor arguments and property values.

Takes a bean class name to avoid eager loading of the bean class.

Parameters:
beanClassName - the name of the class to instantiate
cargs - the constructor argument values to apply
pvs - the property values to apply

RootBeanDefinition

public RootBeanDefinition(RootBeanDefinition original)
Create a new RootBeanDefinition as deep copy of the given bean definition.

Parameters:
original - the original bean definition to copy from
