Protected Methods

Method	Description
AbstractHandler ( ComponentModel model ) : System	Constructs and initializes the handler
AddDependency ( DependencyModel dependency ) : void	Invoked by EnsureDependenciesCanBeSatisfied in order to check if a dependency can be satisfied. If not, the handler is set to a 'waiting dependency' state. This method registers the dependencies within the correct collection or dictionary and changes the handler state to HandlerState.WaitingDependency
CanSatisfyConstructor ( ConstructorCandidate constructor ) : bool
CanSatisfyDependency ( DependencyModel dependency ) : bool
CreateLifestyleManager ( IComponentActivator activator ) : ILifestyleManager	Creates an implementation of ILifestyleManager based on LifestyleType and invokes ILifestyleManager.Init to initialize the newly created manager.
DependencySatisfied ( bool &stateChanged ) : void	Invoked by the kernel when one of registered dependencies were satisfied by new components registered. Handler for the event IKernelEvents.HandlerRegistered
EnsureDependenciesCanBeSatisfied ( IDependencyAwareActivator activator ) : void	Checks if the handler is able to, at very least, satisfy the dependencies for the constructor with less parameters For each non*optional dependency, the implementation will invoke AddDependency
OnAddedAsChildKernel ( object sender, EventArgs e ) : void	Invoked when the container receives a parent container reference. This method implementation checks whether the parent container is able to supply the dependencies for this handler.
Resolve ( CreationContext context, bool instanceRequired ) : object	Returns an instance of the component this handler is responsible for
ResolveCore ( CreationContext context, bool requiresDecommission, bool instanceRequired ) : object	Should be implemented by derived classes: returns an instance of the component this handler is responsible for
SetNewState ( HandlerState newState ) : void
