Method Detail

createResource

protected Resource createResource(OperationContext context)

Description copied from class: AbstractAddStepHandler

Create the Resource that the AbstractAddStepHandler.execute(OperationContext, ModelNode) method operates on.

Overrides:

createResource in class AbstractAddStepHandler

Parameters:

context - the operation context

populateModel

protected void populateModel(org.jboss.dmr.ModelNode operation,
                             org.jboss.dmr.ModelNode model)
                      throws OperationFailedException

Description copied from class: AbstractAddStepHandler

Populate the given node in the persistent configuration model based on the values in the given operation.

Overrides:

populateModel in class AbstractAddStepHandler

Parameters:

operation - the operation

model - persistent configuration model node that corresponds to the address of operation

Throws:

OperationFailedException - if operation is invalid or populating the model otherwise fails

performBoottime

protected void performBoottime(OperationContext context,
                               org.jboss.dmr.ModelNode operation,
                               org.jboss.dmr.ModelNode model,
                               ServiceVerificationHandler verificationHandler,
                               List<org.jboss.msc.service.ServiceController<?>> newControllers)
                        throws OperationFailedException

Description copied from class: AbstractBoottimeAddStepHandler

Make any runtime changes necessary to effect the changes indicated by the given operation. Will only be invoked if OperationContext.isBooting() returns true.

Specified by:

performBoottime in class AbstractBoottimeAddStepHandler

Parameters:

context - the operation context

operation - the operation being executed

model - persistent configuration model node that corresponds to the address of operation

verificationHandler - step handler that can be added as a listener to any new services installed in order to validate the services installed correctly during the VERIFY stage

newControllers - holder for the ServiceController for any new services installed by the method. The method should add the ServiceController for any new services to this list. If the overall operation needs to be rolled back, the list will be used in AbstractBoottimeAddStepHandler.rollbackRuntime(OperationContext, ModelNode, ModelNode, java.util.List) to automatically removed the newly added services

Throws:

OperationFailedException - if operation is invalid or updating the runtime otherwise fails

installProtocolDefaultsService

protected org.jboss.msc.service.ServiceController<ProtocolDefaults> installProtocolDefaultsService(org.jboss.msc.service.ServiceTarget target,
                                                                                                   ServiceVerificationHandler verificationHandler)

installDefaultChannelFactoryService

protected org.jboss.msc.service.ServiceController<ChannelFactory> installDefaultChannelFactoryService(org.jboss.msc.service.ServiceTarget target,
                                                                                                      String stack,
                                                                                                      ServiceVerificationHandler verificationHandler)

requiresRuntimeVerification

protected boolean requiresRuntimeVerification()

Description copied from class: AbstractAddStepHandler

Gets whether the ServiceVerificationHandler parameter passed to AbstractAddStepHandler.performRuntime(OperationContext, org.jboss.dmr.ModelNode, org.jboss.dmr.ModelNode, ServiceVerificationHandler, java.util.List) should be added to the operation context as a step.

This default implementation always returns true.

Overrides:

requiresRuntimeVerification in class AbstractAddStepHandler

Returns:

true if the service verification step should be added; false if it's not necessary.
