* When HK2 automatically analyzes a class to find the constructor, fields,
* initializer methods and postConstruct and preDestroy methods it uses this
* service to analyze the class. This analyzer is only used for descriptors
* that are not pre-reified and which are not provided by factories.
*
* HK2 will provide a default implementation of this service (with the name
* "default"). However, individual descriptors may choose a different class
* analyzer should they so choose. All user supplied implementations of this
* service must have a name. Implementations of this service must not be ClassAnalyzers
* for themselves.
*
* The method {@link ServiceLocator#setDefaultClassAnalyzerName(String)} can be used
* to set the global ClassAnalyzer name that will be the name of the ClassAnalyzer used
* when the method {@link Descriptor#getClassAnalysisName()} returns null
