Support infrastructure for bean definition parsing.

请参阅: 说明

- 接口概要
  接口 | 说明
  --- | ---
  ComponentDefinition | Interface that describes the logical view of a set of `BeanDefinitions` and `BeanReferences` as presented in some configuration context.
  DefaultsDefinition | Marker interface for a defaults definition, extending BeanMetadataElement to inherit source exposure.
  ParseState.Entry | Marker interface for entries into the `ParseState`.
  ProblemReporter | SPI interface allowing tools and other external processes to handle errors and warnings reported during bean definition parsing.
  ReaderEventListener | Interface that receives callbacks for component, alias and import registrations during a bean definition reading process.
  SourceExtractor | Simple strategy allowing tools to control how source metadata is attached to the bean definition metadata.

- 类概要
  类 | 说明
  --- | ---
  AbstractComponentDefinition | Base implementation of `ComponentDefinition` that provides a basic implementation of `AbstractComponentDefinition.getDescription()` which delegates to `ComponentDefinition.getName()`.
  AliasDefinition | Representation of an alias that has been registered during the parsing process.
  BeanComponentDefinition | ComponentDefinition based on a standard BeanDefinition, exposing the given bean definition as well as inner bean definitions and bean references for the given bean.
  BeanEntry | `ParseState` entry representing a bean definition.
  CompositeComponentDefinition | `ComponentDefinition` implementation that holds one or more nested `ComponentDefinition` instances, aggregating them into a named group of components.
  ConstructorArgumentEntry | `ParseState` entry representing a (possibly indexed) constructor argument.
  EmptyReaderEventListener | Empty implementation of the `ReaderEventListener` interface, providing no-op implementations of all callback methods.
  FailFastProblemReporter | Simple `ProblemReporter` implementation that exhibits fail-fast behavior when errors are encountered.
  ImportDefinition | Representation of an import that has been processed during the parsing process.
  Location | Class that models an arbitrary location in a `resource`.
  NullSourceExtractor | Simple implementation of `SourceExtractor` that returns `null` as the source metadata.
  ParseState | Simple `LinkedList`-based structure for tracking the logical position during a parsing process.
  PassThroughSourceExtractor | Simple `SourceExtractor` implementation that just passes the candidate source metadata object through for attachment.
  Problem | Represents a problem with a bean definition configuration.
  PropertyEntry | `ParseState` entry representing a JavaBean property.
  QualifierEntry | `ParseState` entry representing an autowire candidate qualifier.
  ReaderContext | Context that gets passed along a bean definition reading process, encapsulating all relevant configuration as well as state.

- 异常错误概要
  异常错误 | 说明
  --- | ---
  BeanDefinitionParsingException | Exception thrown when a bean definition reader encounters an error during the parsing process.
