Method Detail

getCollectionParameterHolder

protected abstract T getCollectionParameterHolder()

Create new collection impl instance - HashSet, ArrayList, ...

Returns:

new collection impl instance

fillHolder

protected T fillHolder(org.jboss.dependency.spi.Controller controller)
                                           throws Throwable

Fill collection impl with existing context targets.

Parameters:

controller - the controller

Returns:

collection holder with target beans

Throws:

Throwable - for any error

execute

protected void execute(T holder)
                throws Throwable

Throws:

Throwable

createDependencyItem

protected org.jboss.dependency.spi.DependencyItem createDependencyItem(org.jboss.dependency.spi.ControllerContext owner)

Overrides:

createDependencyItem in class org.jboss.dependency.plugins.OwnerCallbackItem<Class,org.jboss.dependency.spi.dispatch.InvokeDispatchContext>

ownerCallback

public void ownerCallback(org.jboss.dependency.spi.Controller controller,
                          boolean isInstallPhase)
                   throws Throwable

Specified by:

ownerCallback in interface org.jboss.dependency.spi.CallbackItem<Class>

Overrides:

ownerCallback in class org.jboss.dependency.plugins.AbstractCallbackItem<Class>

Throws:

Throwable

changeCallback

public void changeCallback(org.jboss.dependency.spi.Controller controller,
                           org.jboss.dependency.spi.ControllerContext context,
                           boolean isInstallPhase)
                    throws Throwable

Specified by:

changeCallback in interface org.jboss.dependency.spi.CallbackItem<Class>

Overrides:

changeCallback in class org.jboss.dependency.plugins.OwnerCallbackItem<Class,org.jboss.dependency.spi.dispatch.InvokeDispatchContext>

Throws:

Throwable

removeUninstallingContext

protected void removeUninstallingContext(T holder,
                                         org.jboss.dependency.spi.ControllerContext context)

Remove the uninstalling context from holder. Since the context is about to change state - not part of callback watched targets. Can be overridden for different remove behaviour.

Parameters:

holder - collection holder

context - current context
