Class PerThreadServiceLifecycle
- java.lang.Object

- org.apache.tapestry5.ioc.internal.services.PerThreadServiceLifecycle
-
- All Implemented Interfaces:
ServiceLifecycle
public class PerThreadServiceLifecycle extends java.lang.Object implements ServiceLifecycle
Allows a service to exist "per thread" (in each thread). Creates a proxy that delegates to a per-thread instance. This scheme ensures that, although the service builder method will be invoked many times over the life of the application, the service decoration process occurs only once. The final calling chain is: Service Proxy --> Interceptor(s) (from Decorators) --> Advise Proxy (from Advisiors) --> PerThread Proxy --> (per thread) instance.

createService
public java.lang.Object createService(ServiceResources resources, ObjectCreator creator)
Description copied from interface:ServiceLifecycleReturns the same creator, or a new one, that encapsulates the creation of the core service implementation.- Specified by:
createServicein interfaceServiceLifecycle- Parameters:
resources- source of information about the service to be created, and source of additional services or other resources that may be needed when constructing the core service implementationcreator- object capable of creating the service implementation on demand. This is a wrapper around the service's builder method.- Returns:
