Constructor Detail

DefaultComponent

public DefaultComponent(Class<? extends Object> klass)

Creates a new DefaultComponent for the given class.

Parameters:

klass - The class used to create new instances.

DefaultComponent

public DefaultComponent(Class<? extends Object> klass,
                        List<Object> initValues)

Creates a new DefaultComponent for the given class with the given init (constructor) values. A constructor with the given init values will be called to instantiate the class.

Parameters:

klass - The class used to create new instances.

initValues - The values for the constructor.

DefaultComponent

public DefaultComponent(Class<? extends Object> klass,
                        Map<String,Object> props)

Creates a new DefaultComponent for the given class with the given property map. The properties will be injected in the instance with reflection.

Parameters:

klass - The class used to create new instances.

props - The properties that need to be injected in each instance.

Specified by:

getType in interface Bean

addProperty

public DefaultComponent addProperty(String name,
                                    Object value)

Adds a property to be set in each new instance of this component's class.

Parameters:

Parameters:

value - The init value to add to this component.

Returns:

This object

addInitValues

public DefaultComponent addInitValues(List values)

Adds the init values from the given list to this component's class. The init values are used to select a constructor for the component's class.

values - The init values to add to this component.

Returns:

This object

getBean

public Object getBean()
               throws InstantiationException

Description copied from interface: Bean
