Invoked by `BeanContextServices`, this method requests an instance of a service from this `BeanContextServiceProvider`.
`void`
`releaseService(BeanContextServices bcs, Object requestor, Object service)`
Invoked by `BeanContextServices`, this method releases a nested `BeanContextChild`'s (or any arbitrary object associated with a `BeanContextChild`) reference to the specified service.

## Method Details

### getService

public Object getService(BeanContextServices bcs, Object requestor, Class<?> serviceClass, Object serviceSelector)
Description copied from interface: `BeanContextServiceProvider`
Invoked by `BeanContextServices`, this method requests an instance of a service from this `BeanContextServiceProvider`.

Specified by:
  `getService` in interface `BeanContextServiceProvider`
Parameters:
  `bcs` - The `BeanContextServices` associated with this particular request. This parameter enables the `BeanContextServiceProvider` to distinguish service requests from multiple sources.
  `requestor` - The object requesting the service
  `serviceClass` - The service requested
  `serviceSelector` - the service dependent parameter for a particular service, or `null` if not applicable.
Returns:
  a reference to the requested service

### releaseService

public void releaseService(BeanContextServices bcs, Object requestor, Object service)
Description copied from interface: `BeanContextServiceProvider`
Invoked by `BeanContextServices`, this method releases a nested `BeanContextChild`'s (or any arbitrary object associated with a `BeanContextChild`) reference to the specified service.

Specified by:
  `releaseService` in interface `BeanContextServiceProvider`
Parameters:
  `bcs` - the `BeanContextServices` associated with this particular release request
  `requestor` - the object requesting the service to be released
  `service` - the service that is to be released

### getCurrentServiceSelectors

public Iterator<?> getCurrentServiceSelectors(BeanContextServices bcs, Class<?> serviceClass)
Description copied from interface: `BeanContextServiceProvider`
Invoked by `BeanContextServices`, this method gets the current service selectors for the specified service. A service selector is a service specific parameter, typical examples of which could include: a parameter to a constructor for the service implementation class, a value for a particular service's property, or a key into a map of existing implementations.

Specified by:
  `getCurrentServiceSelectors` in interface `BeanContextServiceProvider`
Parameters:
  `bcs` - the `BeanContextServices` for this request
  `serviceClass` - the specified service
Returns:
  the current service selectors for the specified serviceClass

### serviceRevoked

public void serviceRevoked(BeanContextServiceRevokedEvent bcsre)
Description copied from interface: `BeanContextServiceRevokedListener`
The service named has been revoked. getService requests for this service will no longer be satisfied.

Specified by:
  `serviceRevoked` in interface `BeanContextServiceRevokedListener`
Parameters:
  `bcsre` - the `BeanContextServiceRevokedEvent` received by this listener.
