public interface OperationStepHandler
A handler is associated with a single stage
of operation execution
and should only perform functions appropriate for that stage.
A handler registered with a ManagementResourceRegistration
will execute in OperationContext.Stage.MODEL
; otherwise the step will execute in the
stage passed to OperationContext.addStep(OperationStepHandler, org.jboss.as.controller.OperationContext.Stage)
when it was added.

void |
execute(OperationContext context,
org.jboss.dmr.ModelNode operation)
Execute this step.
|
void execute(OperationContext context, org.jboss.dmr.ModelNode operation) throws OperationFailedException
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.
