Method Details

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()
