Method Detail

updateModel

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

Description copied from class: AbstractModelUpdateHandler

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

Specified by:

updateModel in class AbstractModelUpdateHandler

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

performRuntime

protected void performRuntime(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: AbstractModelUpdateHandler

Make any runtime changes necessary to effect the changes indicated by the given operation. Executes after AbstractModelUpdateHandler.updateModel(org.jboss.dmr.ModelNode, org.jboss.dmr.ModelNode), so the given model parameter will reflect any changes made in that method.

This default implementation does nothing.

Overrides:

performRuntime in class AbstractModelUpdateHandler

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 AbstractModelUpdateHandler.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

rollbackRuntime

protected void rollbackRuntime(OperationContext context,
                   org.jboss.dmr.ModelNode operation,
                   org.jboss.dmr.ModelNode model,
                   List<org.jboss.msc.service.ServiceController<?>> controllers)

Description copied from class: AbstractModelUpdateHandler

Rollback runtime changes made in AbstractModelUpdateHandler.performRuntime(OperationContext, org.jboss.dmr.ModelNode, org.jboss.dmr.ModelNode, ServiceVerificationHandler, java.util.List).

This default implementation removes all services in the given list of controllers. The contents of controllers is the same as what was in the newControllers parameter passed to performRuntime() when that method returned.

Overrides:

rollbackRuntime in class AbstractModelUpdateHandler

Parameters:

context - the operation context

operation - the operation being executed

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

controllers - holder for the ServiceController for any new services installed by AbstractModelUpdateHandler.performRuntime(OperationContext, org.jboss.dmr.ModelNode, org.jboss.dmr.ModelNode, ServiceVerificationHandler, java.util.List)

getHandlerName

protected String getHandlerName(org.jboss.dmr.ModelNode model)
                         throws OperationFailedException

Description copied from class: AbstractLogHandlerAssignmentHandler

Returns the name of the handler.

Specified by:

getHandlerName in class AbstractLogHandlerAssignmentHandler

Parameters:

model - the model node to retrieve the name from.

Returns:

the handler name.

Throws:

OperationFailedException - if a failure occurs.

addHandler

public static void addHandler(OperationContext context,
              String asyncHandlerName,
              String handlerNameToAdd)
                       throws OperationFailedException

Adds the handler, represented by the handlerNameToRemove parameter, from the async handler.

Parameters:

context - the context of the operation.

asyncHandlerName - the async handler name.

handlerNameToAdd - the name of the handler to add.

Throws:

OperationFailedException - if an error occurs.

addHandlers

public static void addHandlers(AttributeDefinition attribute,
               org.jboss.dmr.ModelNode node,
               OperationContext context,
               String asyncHandlerName)
                        throws OperationFailedException

Adds the subhandlers to the async handler.

Parameters:

attribute - the attribute definition.

node - the model node to extract the subhandlers from.

context - the context of the operation.

Throws:

OperationFailedException - if an error occurs.
