## org.springframework.beans.factory.parsing
Class BeanComponentDefinition

    java.lang.Object
      org.springframework.beans.factory.config.BeanDefinitionHolder
          org.springframework.beans.factory.parsing.BeanComponentDefinition

All Implemented Interfaces:
  BeanMetadataElement, ComponentDefinition

    public class BeanComponentDefinition

extends BeanDefinitionHolder
implements ComponentDefinition

ComponentDefinition based on a standard BeanDefinition, exposing the given bean definition as well as inner bean definitions and bean references for the given bean.

Since:
  2.0
Author:
  Rob Harrop, Juergen Hoeller

Constructor Summary
`BeanComponentDefinition(BeanDefinitionHolder holder)` Create a new BeanComponentDefinition for the given bean.
`BeanComponentDefinition(BeanDefinition beanDefinition, String beanName)` Create a new BeanComponentDefinition for the given bean.
`BeanComponentDefinition(BeanDefinition beanDefinition, String beanName, String[] aliases)` Create a new BeanComponentDefinition for the given bean.

Method Summary
`boolean` | `equals(Object other)` This implementations expects the other object to be of type BeanComponentDefinition as well, in addition to the superclass's equality requirements.
`BeanDefinition[]` | `getBeanDefinitions()` Return the `BeanDefinitions` that were registered to form this `ComponentDefinition`.
`BeanReference[]` | `getBeanReferences()` Return the set of `BeanReferences` that are considered to be important to this `ComponentDefinition`.
`String` | `getDescription()` Return a friendly description of the described component.
`BeanDefinition[]` | `getInnerBeanDefinitions()` Return the `BeanDefinitions` that represent all relevant inner beans within this component.
`String` | `getName()` Get the user-visible name of this `ComponentDefinition`.
`String` | `toString()` This implementation returns this ComponentDefinition's description.

Constructor Detail

### BeanComponentDefinition

    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,
                                   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 holder)

  Create a new BeanComponentDefinition for the given bean.

  Parameters:
    `holder` - 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`
  See Also:
    `getDescription()`

### equals

    public boolean equals(Object other)

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

  Overrides:
    `equals` in class `BeanDefinitionHolder`
