Interface BeanContextServices

All Superinterfaces:
BeanContext, BeanContextChild, BeanContextServiceRevokedListener, BeanContextServicesListener, Collection, DesignMode, EventListener, Iterable, Visibility
All Known Implementing Classes:
BeanContextServicesSupport

@Deprecated(since="23", forRemoval=true) public interface BeanContextServices extends BeanContext, BeanContextServicesListener
Deprecated, for removal: This API element is subject to removal in a future version.

The BeanContextServices interface provides a mechanism for a BeanContext to expose generic "services" to the BeanContextChild objects within.

  • Method Details

    • addService

      boolean addService(Class<?> serviceClass, BeanContextServiceProvider serviceProvider)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Adds a service to this BeanContext. BeanContextServiceProviders call this method to register a particular service with this context. If the service has not previously been added, the BeanContextServices associates the service with the BeanContextServiceProvider and fires a BeanContextServiceAvailableEvent to all currently registered BeanContextServicesListeners. The method then returns true, indicating that the addition of the service was successful. If the given service has already been added, this method simply returns false.
      Parameters:
      serviceClass - the service to add
      serviceProvider - the BeanContextServiceProvider associated with the service
      Returns:
      true if the service was successful added, false otherwise
    • revokeService

      void revokeService(Class<?> serviceClass, BeanContextServiceProvider serviceProvider, boolean revokeCurrentServicesNow)
      Deprecated, for removal: This API element is subject to removal in a future version.
      BeanContextServiceProviders wishing to remove a currently registered service from this context may do so via invocation of this method. Upon revocation of the service, the BeanContextServices fires a BeanContextServiceRevokedEvent to its list of currently registered BeanContextServiceRevokedListeners and BeanContextServicesListeners.
      Parameters:
      serviceClass - the service to revoke from this BeanContextServices
      serviceProvider - the BeanContextServiceProvider associated with this particular service that is being revoked
      revokeCurrentServicesNow - a value of true indicates an exceptional circumstance where the BeanContextServiceProvider or BeanContextServices wishes to immediately terminate service to all currently outstanding references to the specified service.
    • hasService

      boolean hasService(Class<?> serviceClass)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Reports whether or not a given service is currently available from this context.
      Parameters:
      serviceClass - the service in question
      Returns:
      true if the service is available
    • getService

      Object getService(BeanContextChild child, Object requestor, Class<?> serviceClass, Object serviceSelector, BeanContextServiceRevokedListener bcsrl) throws TooManyListenersException
      Deprecated, for removal: This API element is subject to removal in a future version.
      A BeanContextChild, or any arbitrary object associated with a BeanContextChild, may obtain a reference to a currently registered service from its nesting BeanContextServices via invocation of this method. When invoked, this method gets the service by calling the getService() method on the underlying BeanContextServiceProvider.
      Parameters:
      child - the BeanContextChild associated with this request
      requestor - the object requesting the service
      serviceClass - class of the requested service
      serviceSelector - the service dependent parameter
      bcsrl - the BeanContextServiceRevokedListener to notify if the service should later become revoked
      Returns:
      a reference to this context's named Service as requested or null
      Throws:
      TooManyListenersException - if there are too many listeners
    • releaseService

      void releaseService(BeanContextChild child, Object requestor, Object service)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Releases a BeanContextChild's (or any arbitrary object associated with a BeanContextChild) reference to the specified service by calling releaseService() on the underlying BeanContextServiceProvider.
      Parameters:
      child - the BeanContextChild
      requestor - the requestor
      service - the service
    • getCurrentServiceClasses

      Iterator<?> getCurrentServiceClasses()
      Deprecated, for removal: This API element is subject to removal in a future version.
      Gets the currently available services for this context.
      Returns:
      an Iterator consisting of the currently available services
    • getCurrentServiceSelectors

      Iterator<?> getCurrentServiceSelectors(Class<?> serviceClass)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Gets the list of service dependent service parameters (Service Selectors) for the specified service, by calling getCurrentServiceSelectors() on the underlying BeanContextServiceProvider.
      Parameters:
      serviceClass - the specified service
      Returns:
      the currently available service selectors for the named serviceClass
    • addBeanContextServicesListener

      void addBeanContextServicesListener(BeanContextServicesListener bcsl)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Adds a BeanContextServicesListener to this BeanContext
      Parameters:
      bcsl - the BeanContextServicesListener to add
    • removeBeanContextServicesListener

      void removeBeanContextServicesListener(BeanContextServicesListener bcsl)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Removes a BeanContextServicesListener from this BeanContext
      Parameters:
      bcsl - the BeanContextServicesListener to remove from this context
