              org.apache.wicket.guice.InjectionFlagCachingGuiceComponentInjector

All Implemented Interfaces:

IComponentInstantiationListener

public class InjectionFlagCachingGuiceComponentInjector
extends GuiceComponentInjector

Finding the guice annotations via reflection for each Component instantiation is a rather heavyweight operation (@link GuiceComponentInjector. This causes considerable overhead with large lists that have complicated component structure per row, which is totally unnecessary for stock wicket components that do not contain any Guice annotations.

Overrides:

inject in class GuiceComponentInjector

Parameters:

object - object to be injected

onInstantiation

public void onInstantiation(Component component)

Description copied from interface: IComponentInstantiationListener

Called for every component that is instantiated. This method is called during construction, so do not depend on the construction being completed yet. The id is guaranteed to be set before this call.

Specified by:

onInstantiation in interface IComponentInstantiationListener

Overrides:

onInstantiation in class GuiceComponentInjector

Parameters:

component - the component that is being instantiated.
