Class ApplyMissingDomainModelResourcesHandler

java.lang.Object

org.jboss.as.domain.controller.operations.ApplyMissingDomainModelResourcesHandler

All Implemented Interfaces:

OperationStepHandler

public class ApplyMissingDomainModelResourcesHandler
extends Object
implements OperationStepHandler

Step handler used on a slave HC to apply missing parts of the domain model at runtime. This will happen either

• as a result of changing some configuration on the DC, and piggybacking the missing data down from the DC to the slave. The slave then applies these missing resources using this operation handler before changing the configuration in the local DC copy. In this case the ServerOperationHandler is responsible for propagating the restart-required to the affected servers.
• as a result of changing some configuration on the slave, which needs additional data from the DC. The operation handler is then responsible for pulling down the missing data and applying it using this handler. The ServerOperationHandler is again responsible for propagating the restart-required to the affected servers

ApplyRemoteMasterDomainModelHandler contains similar functionality for when a slave connects to the DC.

Method Detail

createPiggyBackedMissingDataOperation

public static org.jboss.dmr.ModelNode createPiggyBackedMissingDataOperation(org.jboss.dmr.ModelNode missingResources)

Creates the operation to invoke when missing data is piggy-backed as a result of a change to the DC model

Parameters:

missingResources - a model node containing the missing resources list

Returns:

the operation

createPulledMissingDataOperation

public static org.jboss.dmr.ModelNode createPulledMissingDataOperation(org.jboss.dmr.ModelNode missingResources)

Creates the operation to invoke when missing data is obtained from the DC as a result of a change to a slave's server-config

Parameters:

missingResources - a model node containing the missing resources list

Returns:

the operation

execute

public void execute(OperationContext context,
                    org.jboss.dmr.ModelNode operation)
             throws OperationFailedException

Description copied from interface: OperationStepHandler

Execute this step. If the operation fails, context.getFailureDescription() must be called, before calling one of the context.completeStep variants, or an OperationFailedException must be thrown. If the operation succeeded, context.getResult() should be called and the result populated with the outcome, after which one of the context.completeStep variants must be called.

When this method is invoked the thread context classloader will be set to be the defining class loader of the class that implements this interface.

Specified by:

execute in interface OperationStepHandler

Parameters:

context - the operation context

operation - the operation being executed

Throws:

OperationFailedException - if the operation failed before calling context.completeStep()

getResource

protected Resource getResource(PathAddress resourceAddress,
                               Resource rootResource,
                               OperationContext context)

initializeExtension

protected void initializeExtension(String module)
                            throws OperationFailedException

Throws:

OperationFailedException
