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, 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

Overrides:

execute in class AbstractWriteAttributeHandler<Void>

Parameters:

context - the operation context

operation - the operation being executed

Throws:

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

finishModelStage

protected void finishModelStage(OperationContext context,
                                org.jboss.dmr.ModelNode operation,
                                String attributeName,
                                org.jboss.dmr.ModelNode newValue,
                                org.jboss.dmr.ModelNode oldValue,
                                Resource model)
                         throws OperationFailedException

Description copied from class: AbstractWriteAttributeHandler

Hook to allow subclasses to do any final OperationContext.Stage.MODEL processing following the application of the new attribute value. This default implementation calls AbstractWriteAttributeHandler.validateUpdatedModel(OperationContext, Resource).

NOTE: Implementations must not call OperationContext.completeStep(OperationContext.ResultHandler) or any of its variants. The method that calls this one handles step completion.

Overrides:

finishModelStage in class AbstractWriteAttributeHandler<Void>

Parameters:

context - the operation context

operation - the operation

attributeName - the name of the attribute being modified

newValue - the new value for the attribute

oldValue - the previous value for the attribute

model - the updated model resource

Throws:

OperationFailedException
