DefaultClassAnalyzer

public DefaultClassAnalyzer(ServiceLocatorImpl locator)

The DefaultClassAnalyzer is per ServiceLocatorImpl

Parameters:

locator - The non-null locator associated with this analyzer

Method Details

getConstructor

public <T> Constructor<T> getConstructor(Class<T> clazz)
                                  throws MultiException,
NoSuchMethodException

Description copied from interface: ClassAnalyzer

Will return the constructor that it to be used when constructing this service

The default implementation will use the zero-arg constructor if no single constructor with Inject is found. Also will return any constructor that is covered by an InjectionResolver and the InjectionResolver.isConstructorParameterIndicator() is set to true

Specified by:

getConstructor in interface ClassAnalyzer

Parameters:

clazz - the non-null class to analyze

Returns:

The non-null constructor to use for creating this service

Throws:

MultiException - on an error when analyzing the class

NoSuchMethodException - if there was no available constructor

getInitializerMethods

public <T> Set<Method> getInitializerMethods(Class<T> clazz)
                                      throws MultiException

Description copied from interface: ClassAnalyzer

Will return the set of initializer method to be used when initializing this service

The default implementation will return all methods marked with Inject or that have a parameter that is covered by an InjectionResolver and the InjectionResolver.isMethodParameterIndicator() is set to true. Also, any method that has a parameter marked with SubscribeTo will NOT be returned, as these methods are instead meant to be called when an event is fired

Specified by:

getInitializerMethods in interface ClassAnalyzer

Parameters:

clazz - the non-null class to analyze

Returns:

A non-null but possibly empty set of initialization methods

Throws:

MultiException - on an error when analyzing the class

getFields

public <T> Set<Field> getFields(Class<T> clazz)
                         throws MultiException

Description copied from interface: ClassAnalyzer

Will return the set of initializer fields to be used when initializing this service

The default implementation will return all fields marked with Inject or that have a parameter that is covered by an InjectionResolver

Specified by:

getFields in interface ClassAnalyzer

Parameters:

clazz - the non-null class to analyze

Returns:

A non-null but possibly empty set of initialization fields

Throws:

MultiException - on an error when analyzing the class

getPostConstructMethod

public <T> Method getPostConstructMethod(Class<T> clazz)
                                  throws MultiException

Description copied from interface: ClassAnalyzer

Will return the postConstruct method of the class

The default implementation will return the PostConstruct.postConstruct() method or the method annotated with PostConstruct

Specified by:

getPostConstructMethod in interface ClassAnalyzer

Parameters:

clazz - the non-null class to analyze

Returns:

A possibly null method representing the postConstruct method to call

Throws:

MultiException - on an error when analyzing the class

getPreDestroyMethod

public <T> Method getPreDestroyMethod(Class<T> clazz)
                               throws MultiException

Description copied from interface: ClassAnalyzer

Will return the preDestroy method of the class

The default implementation will return the PreDestroy.preDestroy() method or the method annotated with PreDestroy

Specified by:

getPreDestroyMethod in interface ClassAnalyzer

Parameters:

clazz - the non-null class to analyze

Returns:

A possibly null method representing the preDestroy method to call

Throws:

MultiException - on an error when analyzing the class
