  • Method Details

    • getState

      public State getState()
      Gets the current state.
      The State being used by the factory bean.
    • isEndState

      public boolean isEndState()
      Description copied from interface: State
      Inquire as to whether a State is an end state. Implementations should return false if processing can continue, even if that would require a restart.
      Specified by:
      isEndState in interface State
      true if this State is the end of processing
    • handle

      public FlowExecutionStatus handle(FlowExecutor executor) throws Exception
      Description copied from interface: State
      Handle some business or processing logic and return a status that can be used to drive a flow to the next State. The status can be any string, but special meaning is assigned to the static constants in FlowExecution. The context can be used by implementations to do whatever they need to do. The same context will be passed to all State instances, so implementations should be careful that the context is thread-safe, or used in a thread-safe manner.
      Specified by:
      handle in interface State
      Specified by:
      handle in class AbstractState
      executor - the context passed in by the caller
      a status for the execution
      Exception - if anything goes wrong
