execute
public final 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 anOperationFailedException
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 thecontext.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:

in interfaceOperationStepHandler
- Parameters:
context
- the operation contextoperation
- the operation being executed- Throws:
OperationFailedException
- if the operation failed before callingcontext.completeStep()
