                           org.jboss.dmr.ModelNode operation,
                           org.jboss.dmr.ModelNode model)
                                throws OperationFailedException

Updates the handlers to be assigned. Checks to see if the handler already exists and throws an exception if it does.

updateHandlersForUnassign

protected void updateHandlersForUnassign(AttributeDefinition handlerAttribute,

                             org.jboss.dmr.ModelNode model)
                                  throws OperationFailedException

Updates the handlers to be unassigned. Checks to see if the handler exists and creates a new list of handlers removing the handler to be unassigned. If the handler to be unassigned does not exist an exception is thrown.

Parameters:

createFailureMessage

protected static OperationFailedException createFailureMessage(String description)

                         throws OperationFailedException

Checks the model, represented my the model parameter, to see if the handler already exists.

Parameters:

handlerName - the name of the handler.

model - the model.

Returns:

true if the handler already exists in the handler listing.

Throws:

OperationFailedException - if an operation failure occurs.

getHandlerName

protected abstract String getHandlerName(org.jboss.dmr.ModelNode model)
                                  throws OperationFailedException
