| Method Summary | |
| public void | addBeanContextServicesListener(BeanContextServicesListener bcsl)
Adds a BeanContextServicesListener to this BeanContext. | | public boolean | addService(Class serviceClass, BeanContextServiceProvider serviceProvider)
Adds a service to this BeanContext. | | public Iterator | getCurrentServiceClasses()
Gets the currently available services for this context. | | public Iterator | getCurrentServiceSelectors(Class serviceClass)
Gets the list of service dependent service parameters
(Service Selectors) for the specified service, by
calling getCurrentServiceSelectors() on the
underlying BeanContextServiceProvider. | | public Object | getService(BeanContextChild child, Object requestor, Class serviceClass, Object serviceSelector, BeanContextServiceRevokedListener bcsrl)
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. | | public synchronized boolean | hasService(Class serviceClass)
Reports whether or not a given service is
currently available from this context. | | protected void | initialize()
Initialize data structures. | | protected synchronized void | releaseBeanContextResources()
Invoked when all resources obtained from the current nested bean context
need to be released. | | public void | releaseService(BeanContextChild child, Object requestor, Object service)
Releases a BeanContextChild's
(or any arbitrary object associated with a BeanContextChild)
reference to the specified service by calling releaseService()
on the underlying BeanContextServiceProvider. | | public void | removeBeanContextServicesListener(BeanContextServicesListener bcsl)
Removes a BeanContextServicesListener
from this BeanContext. | | public void | revokeService(Class serviceClass, BeanContextServiceProvider serviceProvider, boolean revokeCurrentServicesNow)
BeanContextServiceProviders wishing to remove
a currently registered service from this context
may do so via invocation of this method. |
| ControlBeanContextServicesSupport | | public ControlBeanContextServicesSupport()(Code) | | Constructor.
|
| ControlBeanContextServicesSupport | | public ControlBeanContextServicesSupport(BeanContextServices peer)(Code) | | Constructor which allows delegate to be passed in.
Parameters:
peer - BeanContextServices peer. |
| addBeanContextServicesListener | | public void addBeanContextServicesListener(BeanContextServicesListener bcsl)(Code) | | Adds a BeanContextServicesListener to this BeanContext.
Parameters:
bcsl - the BeanContextServicesListener to add |
| addService | | public boolean addService(Class serviceClass, BeanContextServiceProvider serviceProvider)(Code) | | 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
Parameters:
serviceProvider - the BeanContextServiceProviderassociated with the service true if service was added. |
| getCurrentServiceClasses | | public Iterator getCurrentServiceClasses()(Code) | | Gets the currently available services for this context.
an Iterator consisting of thecurrently available services |
| getCurrentServiceSelectors | | public Iterator getCurrentServiceSelectors(Class serviceClass)(Code) | | 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 the currently available service selectorsfor the named serviceClass |
| getService | | public Object getService(BeanContextChild child, Object requestor, Class serviceClass, Object serviceSelector, BeanContextServiceRevokedListener bcsrl) throws TooManyListenersException(Code) | | 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 BeanContextChildassociated with this request
Parameters:
requestor - the object requesting the service
Parameters:
serviceClass - class of the requested service
Parameters:
serviceSelector - the service dependent parameter
Parameters:
bcsrl - theBeanContextServiceRevokedListener to notifyif the service should later become revoked a reference to this context's namedService as requested or null
throws:
java.util.TooManyListenersException - |
| hasService | | public synchronized boolean hasService(Class serviceClass)(Code) | | Reports whether or not a given service is
currently available from this context.
Parameters:
serviceClass - the service in question true if the service is available |
| initialize | | protected void initialize()(Code) | | Initialize data structures.
|
| releaseBeanContextResources | | protected synchronized void releaseBeanContextResources()(Code) | | Invoked when all resources obtained from the current nested bean context
need to be released. For BeanContextServices this means revoke any services
obtained from a delegate services provider. Typically invoked when the parent
context is changed.
|
| releaseService | | public void releaseService(BeanContextChild child, Object requestor, Object service)(Code) | | 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
Parameters:
requestor - the requestor
Parameters:
service - the service |
| removeBeanContextServicesListener | | public void removeBeanContextServicesListener(BeanContextServicesListener bcsl)(Code) | | Removes a BeanContextServicesListener
from this BeanContext.
Parameters:
bcsl - the BeanContextServicesListenerto remove from this context |
| revokeService | | public void revokeService(Class serviceClass, BeanContextServiceProvider serviceProvider, boolean revokeCurrentServicesNow)(Code) | | 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
Parameters:
serviceProvider - the BeanContextServiceProvider associated withthis particular service that is being revoked
Parameters:
revokeCurrentServicesNow - a value of trueindicates an exceptional circumstance where theBeanContextServiceProvider orBeanContextServices wishes to immediatelyterminate service to all currently outstanding referencesto the specified service. |
