Method Summary

Modifier and TypeMethod and Description
public <T> Constructor<T>
getConstructor(Class<T> clazz)

Implements org.glassfish.hk2.api.ClassAnalyzer.getConstructor.

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.

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

Implements org.glassfish.hk2.api.ClassAnalyzer.getFields.

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

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

Implements org.glassfish.hk2.api.ClassAnalyzer.getInitializerMethods.

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.

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

Implements org.glassfish.hk2.api.ClassAnalyzer.getPostConstructMethod.

Will return the postConstruct method of the class

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

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

Implements org.glassfish.hk2.api.ClassAnalyzer.getPreDestroyMethod.

Will return the preDestroy method of the class

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