InjectionManager (Jersey 2.45 API)

All Known Implementing Classes:

CdiSeInjectionManager, DelayedHk2InjectionManager, ImmediateHk2InjectionManager
```
public interface InjectionManager
```
Interface provides the communication API between Jersey and Dependency Injection provider.
Lifecycle methods should be called in this order:
- completeRegistration() - notifies that Jersey bootstrap has been finished and DI provider should be ready for a runtime.
- shutdown() - Jersey application has been closed and DI provider should make needed cleaning steps.
All getInstance methods can be called after completeRegistration() method has been called because at this all components are bound to injection manager and ready for getting. In turn, shutdown() method stops the possibility to use these methods and closes InjectionManager.

- Method Detail
  - completeRegistration
```
void completeRegistration()
```
    Completes InjectionManager and the underlying DI provider. All registered components are bound to injection manager and after an invocation of this method all components are available using e.g. getInstance(Class).
  - shutdown
```
void shutdown()
```
    Shuts down the entire InjectionManager and the underlying DI provider.
    Shutdown phase is dedicated to make some final cleaning steps regarding underlying DI provider.
  - isShutdown
```
boolean isShutdown()
```
    Returns true when the InjectionManager has been shutdown, false otherwise.
    
    Returns:
    
    Whether the InjectionManager has been shutdown.
  - register
```
void register(Binding binding)
```
    Registers one bean represented using fields in the provided descriptor. The final bean can be direct bean or factory object which will create the bean at the time of injection. InjectionManager is able to register a bean represented by a class or direct instance.
    
    Parameters:
    
    binding - one descriptor.
    
    See Also:
    
    ClassBinding, InstanceBinding, SupplierClassBinding, SupplierInstanceBinding
  - register
```
void register(Iterable<Binding> descriptors)
```
    Registers a collection of beans represented using fields in the provided descriptors. The final bean can be direct bean or factory object which will create the bean at the time of injection. InjectionManager is able to register a bean represented by a class or direct instance.
    
    Parameters:
    
    descriptors - collection of descriptors.
    
    See Also:
    
    ClassBinding, InstanceBinding, SupplierClassBinding, SupplierInstanceBinding
  - register
```
void register(Binder binder)
```
    Registers beans which are included in Binder. Binder can contains all descriptors extending Binding or other binders which are installed together in tree-structure. This method will get all descriptors bound in the given binder and register them in the order how the binders are installed together. In the tree structure, the deeper on the left side will be processed first.
    
    Parameters:
    
    binder - collection of descriptors.
    
    See Also:
    
    ClassBinding, InstanceBinding, SupplierClassBinding, SupplierInstanceBinding
  - register
```
void register(Object provider)
       throws IllegalArgumentException
```
    Registers a provider. An implementation of the InjectionManager should test whether the type of the object can be registered using the method isRegistrable(Class). Then a caller has an certainty that the instance of the tested class can be registered in InjectionManager. If InjectionManager is not able to register the provider then IllegalArgumentException is thrown.
    
    Parameters:
    
    provider - object that can be registered in InjectionManager.
    
    Throws:
    
    IllegalArgumentException - provider cannot be registered.
  - isRegistrable
```
boolean isRegistrable(Class<?> clazz)
```
    Tests whether the provided clazz can be registered by the implementation of the InjectionManager.
    
    Parameters:
    
    clazz - type that is tested whether is registrable by the implementation of InjectionManager.
    
    Returns:
    
    true if the InjectionManager is able to register this type.
  - create
```
<T> T create(Class<T> createMe)
```
    Creates an object with the given class.
    The object created is not managed by the injection manager.
    
    Parameters:
    
    createMe - The non-null class to create this object from;
    
    Returns:
    
    An instance of the object that has been created.
    
    Since:
    
    2.35
  - createAndInitialize
```
<T> T createAndInitialize(Class<T> createMe)
```
    Creates, injects and post-constructs an object with the given class. This is equivalent to calling the create-class method followed by the inject-class method followed by the post-construct method.
    The object created is not managed by the injection manager.
    
    Parameters:
    
    createMe - The non-null class to create this object from;
    
    Returns:
    
    An instance of the object that has been created, injected and post constructed.
