Allows certain types of lifecycles to control exactly how services are instantiated.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	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 true if the lifecycle is a singleton (a service that will only be created once).

- Method Detail
  - createService
```
Object createService(ServiceResources resources,
                     ObjectCreator creator)
```
    Returns the same creator, or a new one, that encapsulates the creation of the core service implementation.
    
    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
  - isSingleton
```
boolean isSingleton()
```
    Returns true if the lifecycle is a singleton (a service that will only be created once). Return false if the underlying service instance may be created multiple times (for example, the ScopeConstants.PERTHREAD scope}. A future version of Tapestry IoC may optimize for the later case.
    
    Returns:
    
    true for singletons, false for services that can be repeatedly constructed
