## 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.

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `Object` | `createService(ServiceResources resources, ObjectCreator creator)` Returns the same creator, or a new one, that encapsulates the creation of the core service implementation.
    `boolean` | `isSingleton()` Returns false; this lifecycle represents a service that will be created many times (by each thread).

    - #### PerThreadServiceLifecycle

          public PerThreadServiceLifecycle(@Builtin
                                   PerthreadManager perthreadManager,
                                   @Builtin
                                   PlasticProxyFactory proxyFactory)

  - ### Method Detail

    - #### 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
