  - setSource
```
public void setSource(Object source)
```
    Set the configuration source Object for this metadata element.
    The exact type of the object will depend on the configuration mechanism used.
  - getSource
```
public Object getSource()
```
    Description copied from interface: BeanMetadataElement
    Return the configuration source Object for this metadata element (may be null).
    Specified by:
    getSource in interface BeanMetadataElement
  - addMetadataAttribute
```
public void addMetadataAttribute(BeanMetadataAttribute attribute)
```
    Add the given BeanMetadataAttribute to this accessor's set of attributes.
    Parameters:
    attribute - the BeanMetadataAttribute object to register
  - getMetadataAttribute
```
public BeanMetadataAttribute getMetadataAttribute(String name)
```
    Look up the given BeanMetadataAttribute in this accessor's set of attributes.
    Parameters:
    name - the name of the attribute
    Returns:
    the corresponding BeanMetadataAttribute object, or null if no such attribute defined
  - setAttribute
```
public void setAttribute(String name,
                         Object value)
```
    Description copied from interface: AttributeAccessor
    Set the attribute defined by name to the supplied value. If value is null, the attribute is removed.
    In general, users should take care to prevent overlaps with other metadata attributes by using fully-qualified names, perhaps using class or package names as prefix.
    Specified by:
    setAttribute in interface AttributeAccessor
    Overrides:
    setAttribute in class AttributeAccessorSupport
    Parameters:
    name - the unique attribute key
    value - the attribute value to be attached
  - getAttribute
```
public Object getAttribute(String name)
```
    Description copied from interface: AttributeAccessor
    Get the value of the attribute identified by name. Return null if the attribute doesn't exist.
    Specified by:
    getAttribute in interface AttributeAccessor
    Overrides:
    getAttribute in class AttributeAccessorSupport
    Parameters:
    name - the unique attribute key
    Returns:
    the current value of the attribute, if any
  - removeAttribute
```
public Object removeAttribute(String name)
```
    Description copied from interface: AttributeAccessor
    Remove the attribute identified by name and return its value. Return null if no attribute under name is found.
    Specified by:
    removeAttribute in interface AttributeAccessor
    Overrides:

    Parameters:
    name - the unique attribute key
    Returns:
    the last value of the attribute, if any
