public BeanComponentDefinition(BeanDefinition beanDefinition,
                               String beanName)

Create a new BeanComponentDefinition for the given bean.

Parameters:

beanDefinition - the BeanDefinition

beanName - the name of the bean

BeanComponentDefinition

public BeanComponentDefinition(BeanDefinition beanDefinition,
                               String beanName,
                               @Nullable
                               String[] aliases)

Create a new BeanComponentDefinition for the given bean.

Parameters:

beanDefinition - the BeanDefinition

beanName - the name of the bean

aliases - alias names for the bean, or null if none

BeanComponentDefinition

public BeanComponentDefinition(BeanDefinitionHolder beanDefinitionHolder)

Create a new BeanComponentDefinition for the given bean.

Parameters:

beanDefinitionHolder - the BeanDefinitionHolder encapsulating the bean definition as well as the name of the bean

Method Detail

getName

public String getName()

Description copied from interface: ComponentDefinition

Get the user-visible name of this ComponentDefinition.

This should link back directly to the corresponding configuration data for this component in a given context.

Specified by:

getName in interface ComponentDefinition

getDescription

public String getDescription()

Description copied from interface: ComponentDefinition

Return a friendly description of the described component.

Implementations are encouraged to return the same value from toString().

Specified by:

getDescription in interface ComponentDefinition

getBeanDefinitions

public BeanDefinition[] getBeanDefinitions()

Description copied from interface: ComponentDefinition

Return the BeanDefinitions that were registered to form this ComponentDefinition.

It should be noted that a ComponentDefinition may well be related with other BeanDefinitions via references, however these are not included as they may be not available immediately. Important BeanReferences are available from ComponentDefinition.getBeanReferences().

Specified by:

getBeanDefinitions in interface ComponentDefinition

Returns:

the array of BeanDefinitions, or an empty array if none

getInnerBeanDefinitions

public BeanDefinition[] getInnerBeanDefinitions()

Description copied from interface: ComponentDefinition

Return the BeanDefinitions that represent all relevant inner beans within this component.

Other inner beans may exist within the associated BeanDefinitions, however these are not considered to be needed for validation or for user visualization.

Specified by:

getInnerBeanDefinitions in interface ComponentDefinition

Returns:

the array of BeanDefinitions, or an empty array if none

getBeanReferences

public BeanReference[] getBeanReferences()

Description copied from interface: ComponentDefinition

Return the set of BeanReferences that are considered to be important to this ComponentDefinition.

Other BeanReferences may exist within the associated BeanDefinitions, however these are not considered to be needed for validation or for user visualization.

Specified by:

getBeanReferences in interface ComponentDefinition

Returns:

the array of BeanReferences, or an empty array if none

toString

public String toString()

This implementation returns this ComponentDefinition's description.

Overrides:

toString in class BeanDefinitionHolder

equals

public boolean equals(@Nullable
                      Object other)

This implementation expects the other object to be of type BeanComponentDefinition as well, in addition to the superclass's equality requirements.

Overrides:

equals in class BeanDefinitionHolder
