Constructor Detail

### DefaultInjector

    public DefaultInjector(Module... modules)
                    throws ConfigurationException

Throws:
  `ConfigurationException`

Method Detail

### getInstance

    public <T> T getInstance(Class<T> type)
                  throws ConfigurationException

  Description copied from interface: `Injector`
  Returns a service instance bound in the container for a specific type. Throws `ConfigurationException` if the type is not bound, or an instance can not be created.

  Specified by:
    `getInstance` in interface `Injector`
  Throws:
    `ConfigurationException`

### getInstance

    public <T> T getInstance(Key<T> key)
                  throws ConfigurationException

  Description copied from interface: `Injector`
  Returns a service instance bound in the container for a specific binding key. Throws `ConfigurationException` if the key is not bound, or an instance can not be created.

  Specified by:
    `getInstance` in interface `Injector`
  Throws:
    `ConfigurationException`

### getProvider

    public <T> Provider<T> getProvider(Class<T> type)
                            throws ConfigurationException

  Specified by:
    `getProvider` in interface `Injector`
  Throws:
    `ConfigurationException`

### getProvider

    public <T> Provider<T> getProvider(Key<T> key)
                            throws ConfigurationException

  Specified by:
    `getProvider` in interface `Injector`
  Throws:
    `ConfigurationException`

### injectMembers

    public void injectMembers(Object object)

  Description copied from interface: `Injector`
  Performs field injection on a given object, ignoring constructor injection. Since Cayenne DI injector returns fully injected objects, this method is rarely used directly.

  Note that using this method inside a custom DI `Provider` will most likely result in double injection, as custom provider is wrapped in a field-injecting provider by the DI container. Instead custom providers must initialize object properties manually, obtaining dependencies from Injector.

  Specified by:
    `injectMembers` in interface `Injector`

### shutdown

    public void shutdown()

  Description copied from interface: `Injector`
  A lifecycle method that let's the injector's services to clean up their state and release resources. This method would normally generate a scope end event for the injector's one and only singleton scope.

  Specified by:
    `shutdown` in interface `Injector`
