public class RootBeanDefinition

extends AbstractBeanDefinition

Root bean definitions have a class plus optionally constructor argument values and property values. This is the most common type of bean definition.

The autowire constants match the ones defined in the AutowireCapableBeanFactory interface, adding AUTOWIRE_NO.

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

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)

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

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

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

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

public RootBeanDefinition(RootBeanDefinition other)

Deep copy constructor.

public int getAutowireMode()

Return the autowire mode as specified in the bean definition.

public final Class getBeanClass()
                          throws java.lang.IllegalStateException

Returns the class of the wrapped bean.

Throws:

IllegalStateException - if the bean definition does not carry a resolved bean class

public final String getBeanClassName()

Returns the class name of the wrapped bean.

public ConstructorArgumentValues getConstructorArgumentValues()

Return the constructor argument values for this bean.

public int getDependencyCheck()

Return the dependency check code.

public String[] getDependsOn()

Return the bean names that this bean depends on.

public String getDestroyMethodName()

Return the name of the destroy method.

public String getInitMethodName()

Return the name of the initializer method.

public int getResolvedAutowireMode()

Return the resolved autowire code, (resolving AUTOWIRE_AUTODETECT to AUTOWIRE_CONSTRUCTOR or AUTOWIRE_BY_TYPE).

See Also:

AUTOWIRE_AUTODETECT, AUTOWIRE_CONSTRUCTOR, AUTOWIRE_BY_TYPE

public boolean hasConstructorArgumentValues()

Return if there are constructor argument values for this bean.

public void setAutowireMode(int autowireMode)

Set the autowire code. This determines whether any automagical detection and setting of bean references will happen. Default is AUTOWIRE_NO, which means there's no autowire.

Parameters:

autowireMode - the autowire to set. Must be one of the constants defined in this class.

See Also:

AUTOWIRE_NO, AUTOWIRE_BY_NAME, AUTOWIRE_BY_TYPE, AUTOWIRE_CONSTRUCTOR, AUTOWIRE_AUTODETECT

public void setDependencyCheck(int dependencyCheck)

Set the dependency check code.

Parameters:

dependencyCheck - the code to set. Must be one of the four constants defined in this class.

See Also:

DEPENDENCY_CHECK_NONE, DEPENDENCY_CHECK_OBJECTS, DEPENDENCY_CHECK_SIMPLE, DEPENDENCY_CHECK_ALL

public void setDependsOn(String[] dependsOn)

Set the names of the beans that this bean depends on being initialized. The bean factory will guarantee that these beans get initialized before.

Note that dependencies are normally expressed through bean properties or constructor arguments. This property should just be necessary for other kinds of dependencies like statics (*ugh*) or database preparation on startup.

public void setDestroyMethodName(String destroyMethodName)

Set the name of the destroy method. The default is null in which case there is no destroy method.

public void setInitMethodName(String initMethodName)

Set the name of the initializer method. The default is null in which case there is no initializer method.

public String toString()

public void validate()
               throws BeanDefinitionValidationException
