Method Detail

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, or an OperationFailedException must be thrown. If the operation succeeded and the operation provides a return value, context.getResult() should be called and the result populated with the outcome. If the handler wishes to take further action once the result of the overall operation execution is known, one of the context.completeStep variants should be called to register a callback. The callback will not be invoked if this method throws an exception.

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()

performRemove

protected void performRemove(OperationContext context,
                 org.jboss.dmr.ModelNode operation,
                 org.jboss.dmr.ModelNode model)
                      throws OperationFailedException

Throws:

OperationFailedException

recordCapabilitiesAndRequirements

protected void recordCapabilitiesAndRequirements(OperationContext context,
                                     org.jboss.dmr.ModelNode operation,
                                     Resource resource)
                                          throws OperationFailedException

Record any new capabilities that are no longer available as a result of this operation, as well as any requirements for other capabilities that no longer exist. This method is invoked during OperationContext.Stage.MODEL.

Any changes made by this method will automatically be discarded if the operation rolls back.

This default implementation deregisters any capabilities passed to the constructor.

Parameters:

context - the context. Will not be null

operation - the operation that is executing Will not be null

resource - the resource that has been added. Will not reflect any updates made by performRemove(OperationContext, org.jboss.dmr.ModelNode, org.jboss.dmr.ModelNode) as this method is invoked before that method is. Will not be null

Throws:

OperationFailedException

requireNoChildResources

protected boolean requireNoChildResources()

performRuntime

protected void performRuntime(OperationContext context,
                  org.jboss.dmr.ModelNode operation,
                  org.jboss.dmr.ModelNode model)
                       throws OperationFailedException

Throws:

OperationFailedException

recoverServices

protected void recoverServices(OperationContext context,
                   org.jboss.dmr.ModelNode operation,
                   org.jboss.dmr.ModelNode model)
                        throws OperationFailedException

Throws:

OperationFailedException

requiresRuntime

protected boolean requiresRuntime(OperationContext context)
