org.apache.tapestry5.ioc
public interface: ObjectProvider [javadoc |
source]
All Known Implementing Classes:
ServiceAnnotationObjectProvider, SymbolObjectProvider, AssetObjectProvider, AliasImpl, ValueObjectProvider
Object providers represent an alternate way to locate an object provided somewhere in the
org.apache.tapestry5.ioc.Registry . Instead of using a just the service id to gain access to a service within the
Registry, object providers in different flavors are capable of vending, or even creating, objects of disparate types
from disparate sources.
Object providers are consulted in a strict order, and the first non-null result is taken.
In many cases, an object provider searches for additional annotations on the element (usually a parameter, or perhaps
a field) for which a value is required.

 public T provide(Class<T> objectType,
AnnotationProvider annotationProvider,
ObjectLocator locator)
Provides an object based on an expression. The process of providing objects occurs within a particular
context, which will typically be a service builder method, service contributor method, or service
decorator method. The locator parameter provides access to the services visible to that context. |
