| org.apache.tapestry.ioc.services.PropertyShadowBuilder
All known Subclasses: org.apache.tapestry.ioc.internal.services.PropertyShadowBuilderImpl,
| PropertyShadowBuilder | | public interface PropertyShadowBuilder (Code) | | Creates a "shadow" of a property of an object. The shadow has the same type as the property, and
delegates all method invocations to the property. Each method invocation on the shadow
re-acquires the value of the property from the underlying object and delegates to the current
value of the property.
Typically, the object in question is another service, one with the "perthread" service lifecycle.
This allows a global singleton to shadow a value that is specific to the current thread (and
therefore, the current request).
