public interface IProvider
The interface for all service providers. Specifies a part of the contract
between a service and its providers:
- A service can listen to its provider
- A service can request a provider whether it wants to support a given
request
Service implementers are expected to expose service specific classes
implementing this interface.
Service provider implementers never need to implement this interface
directly, they instead derive their provider implementation from the service
specific implementation of this interface.
addProviderChangeListener
void addProviderChangeListener(
IProviderChangeListener listener)
- Adds the specified listener to the list of provider change listeners for
this provider.
-
-
Parameters:
-
listener - The listener to be added.
provides
boolean provides(
IOperation operation)
- Indicates whether this provider provides the specified operation.
Providers generally cast the operation to a service specific
IOperation-derived class in order to determine whether they
support the request.
-
-
Parameters:
-
operation - The operation in question.
-
Returns:
-
true if this provider provides the operation;
false otherwise.
removeProviderChangeListener
void removeProviderChangeListener(
IProviderChangeListener listener)
- Removes the specified listener from the list of provider change listeners
for this provider.
-
-
Parameters:
-
listener - The listener to be removed.
