public abstract class AbstractSingleBeanDefinitionParser
extends AbstractBeanDefinitionParser
```
Base class for those BeanDefinitionParser implementations that need to parse and define just a singleBeanDefinition.
Extend this parser class when you want to create a single bean definition from an arbitrarily complex XML element. You may wish to consider extending the AbstractSimpleBeanDefinitionParser when you want to create a single bean definition from a relatively simple custom XML element.
The resulting BeanDefinition will be automatically registered with the BeanDefinitionRegistry. Your job simply is to parse the custom XML Element into a single BeanDefinition.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected void`	`doParse(Element element, BeanDefinitionBuilder builder)`	Parse the supplied `Element` and populate the supplied `BeanDefinitionBuilder` as required.
`protected void`	`doParse(Element element, ParserContext parserContext, BeanDefinitionBuilder builder)`	Parse the supplied `Element` and populate the supplied `BeanDefinitionBuilder` as required.
`protected Class<?>`	`getBeanClass(Element element)`	Determine the bean class corresponding to the supplied `Element`.
`protected String`	`getBeanClassName(Element element)`	Determine the bean class name corresponding to the supplied `Element`.
`protected String`	`getParentName(Element element)`	Determine the name for the parent of the currently parsed bean, in case of the current bean being defined as a child bean.
`protected AbstractBeanDefinition`	`parseInternal(Element element, ParserContext parserContext)`	Creates a `BeanDefinitionBuilder` instance for the `bean Class` and passes it to the `doParse(org.w3c.dom.Element, org.springframework.beans.factory.xml.ParserContext, org.springframework.beans.factory.support.BeanDefinitionBuilder)` strategy method.

public AbstractSingleBeanDefinitionParser()

- Method Detail
  - parseInternal
```
protected final AbstractBeanDefinition parseInternal(Element element,
                                                     ParserContext parserContext)
```
    Creates a BeanDefinitionBuilder instance for the bean Class and passes it to the doParse(org.w3c.dom.Element, org.springframework.beans.factory.xml.ParserContext, org.springframework.beans.factory.support.BeanDefinitionBuilder) strategy method.
    Specified by:
    parseInternal in class AbstractBeanDefinitionParser
    Parameters:
    element - the element that is to be parsed into a single BeanDefinition
    parserContext - the object encapsulating the current state of the parsing process
    Returns:
    the BeanDefinition resulting from the parsing of the supplied Element
    Throws:
    IllegalStateException - if the bean Class returned from getBeanClass(org.w3c.dom.Element) is null
    See Also:
    doParse(org.w3c.dom.Element, org.springframework.beans.factory.xml.ParserContext, org.springframework.beans.factory.support.BeanDefinitionBuilder)
  - getParentName
```
protected String getParentName(Element element)
```
    Determine the name for the parent of the currently parsed bean, in case of the current bean being defined as a child bean.
    The default implementation returns null, indicating a root bean definition.
    Parameters:
    element - the Element that is being parsed
    Returns:
    the name of the parent bean for the currently parsed bean, or null if none
  - getBeanClass
```
protected Class<?> getBeanClass(Element element)
```
    Determine the bean class corresponding to the supplied Element.
    Note that, for application classes, it is generally preferable to override getBeanClassName(org.w3c.dom.Element) instead, in order to avoid a direct dependence on the bean implementation class. The BeanDefinitionParser and its NamespaceHandler can be used within an IDE plugin then, even if the application classes are not available on the plugin's classpath.
    Parameters:
    element - the Element that is being parsed
    Returns:
    the Class of the bean that is being defined via parsing the supplied Element, or null if none
    See Also:
    getBeanClassName(org.w3c.dom.Element)
  - getBeanClassName
```
protected String getBeanClassName(Element element)
```
    Determine the bean class name corresponding to the supplied Element.
    Parameters:
    element - the Element that is being parsed
    Returns:
    the class name of the bean that is being defined via parsing the supplied Element, or null if none
    See Also:
    getBeanClass(org.w3c.dom.Element)
  - doParse
```
protected void doParse(Element element,
                       ParserContext parserContext,
                       BeanDefinitionBuilder builder)
```
    Parse the supplied Element and populate the supplied BeanDefinitionBuilder as required.
    The default implementation delegates to the doParse version without ParserContext argument.
    Parameters:
    element - the XML element being parsed
    parserContext - the object encapsulating the current state of the parsing process
    builder - used to define the BeanDefinition
    See Also:
    doParse(Element, BeanDefinitionBuilder)
  - doParse
```
protected void doParse(Element element,
                       BeanDefinitionBuilder builder)
```
    Parse the supplied Element and populate the supplied BeanDefinitionBuilder as required.
    The default implementation does nothing.
    Parameters:
    element - the XML element being parsed
    builder - used to define the BeanDefinition
