## Class SequencerWriteAttributeHandler

- java.lang.Object
- - org.jboss.as.controller.AbstractWriteAttributeHandler<Void>
  - - org.modeshape.jboss.subsystem.AbstractRepositoryConfigWriteAttributeHandler
    - - org.modeshape.jboss.subsystem.SequencerWriteAttributeHandler

- All Implemented Interfaces:
    org.jboss.as.controller.OperationStepHandler

      public class SequencerWriteAttributeHandler
      extends AbstractRepositoryConfigWriteAttributeHandler

  An `OperationStepHandler` implementation that handles changes to the model values for a sequencer submodel's `attribute definitions`. Those attributes that can be changed `RESTART_NONE without restarting` will be immediately reflected in the repository's configuration; other attributes will be changed in the submodel and used upon the next restart.
