Constructor Detail

Reinjector

public Reinjector(PicoContainer parentContainer)

Make a reinjector with a parent container from which to pull components to be reinjected to. With this constructor, a NullComponentMonitor is used.

Parameters:

parentContainer - the parent container

Reinjector

public Reinjector(PicoContainer parentContainer,
                  ComponentMonitor monitor)

Make a reinjector with a parent container from which to pull components to be reinjected to

Parameters:

parentContainer - the parent container

monitor - the monitor to use for 'instantiating' events

Method Detail

reinject

public Object reinject(Class<?> key,
                       Method reinjectionMethod)

Reinjecting into a method.

Parameters:

key - the component-key from the parent set of components to inject into

reinjectionMethod - the reflection method to use for injection.

Returns:

the result of the reinjection-method invocation.

reinject

public Object reinject(Class<?> key,
                       Enum reinjectionMethodEnum)

Reinjecting into a method.

Parameters:

key - the component-key from the parent set of components to inject into

reinjectionMethodEnum - the enum for the reflection method to use for injection.

Returns:

the result of the reinjection-method invocation.

reinject

public Object reinject(Class<?> key,
                       InjectionFactory reinjectionFactory)

Reinjecting into a method.

Parameters:

key - the component-key from the parent set of components to inject into (key and impl are the same)

reinjectionFactory - the InjectionFactory to use for reinjection.

Returns:

the result of the reinjection-method invocation.

reinject

public Object reinject(Class<?> key,
                       Class<?> impl,
