public class SetterInjector<T> extends IterativeInjector<T>
Instantiates components using empty constructors and Setter Injection. For easy setting of primitive properties, also seePropertyApplicator
. Note that this class doesn't cache instances. If you want caching, use aCached

SetterInjector
public SetterInjector(Object componentKey, Class componentImplementation, Parameter[] parameters, ComponentMonitor monitor, String prefix, String notThisOneThough, boolean optional, boolean useNames) throws AbstractInjector.NotConcreteRegistrationException
Constructs a SetterInjector- Parameters:
componentKey
- the search key for this implementationcomponentImplementation
- the concrete implementationparameters
- the parameters to use for the initializationmonitor
- the component monitor used by this addAdapterprefix
- the prefix to use (e.g. 'set')notThisOneThough
- a setter name that's not for injecting throughoptional
- not all setters need to be injecteduseNames
-- Throws:
AbstractInjector.NotConcreteRegistrationException
- if the implementation is not a concrete class.NullPointerException
- if one of the parameters isnull
