Class PerThreadServiceLifecycle

java.lang.Object
org.apache.tapestry5.ioc.internal.services.PerThreadServiceLifecycle
All Implemented Interfaces:
ServiceLifecycle

public class PerThreadServiceLifecycle extends 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.

    • isSingleton

      public boolean isSingleton()
      Returns false; this lifecycle represents a service that will be created many times (by each thread).
      Specified by:
      isSingleton in interface ServiceLifecycle
      Returns:
      true for singletons, false for services that can be repeatedly constructed
    • createService

      public Object createService(ServiceResources resources, ObjectCreator creator)
      Description copied from interface: ServiceLifecycle
      Returns the same creator, or a new one, that encapsulates the creation of the core service implementation.
      Specified by:
      createService in interface ServiceLifecycle
      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 implementation
      creator - object capable of creating the service implementation on demand. This is a wrapper around the service's builder method.
      Returns:
      the service or equivalent service proxy
