## org.modeshape.jboss.subsystem
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.
