## Interface POAManagerOperations

- All Known Subinterfaces:
    POAManager

      public interface POAManagerOperations

  Each POA object has an associated POAManager object. A POA manager may be associated with one or more POA objects. A POA manager encapsulates the processing state of the POAs it is associated with.

- - ### Method Summary

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `activate()` This operation changes the state of the POA manager to active, causing associated POAs to start processing requests.
    `void` | `deactivate(boolean etherealize_objects, boolean wait_for_completion)` This operation changes the state of the POA manager to inactive, causing associated POAs to reject the requests that have not begun executing as well as as any new requests.
    `void` | `discard_requests(boolean wait_for_completion)` This operation changes the state of the POA manager to discarding.
    `State` | `get_state()` This operation returns the state of the POA manager.
    `void` | `hold_requests(boolean wait_for_completion)` This operation changes the state of the POA manager to holding, causing associated POAs to queue incoming requests.

- - ### Method Detail

    - #### activate

          void activate()
                 throws AdapterInactive

      This operation changes the state of the POA manager to active, causing associated POAs to start processing requests.
      Throws:
        `AdapterInactive` - is raised if the operation is invoked on the POAManager in inactive state.

    - #### hold_requests

          void hold_requests(boolean wait_for_completion)
                      throws AdapterInactive

      This operation changes the state of the POA manager to holding, causing associated POAs to queue incoming requests.
      Parameters:
        `wait_for_completion` - if FALSE, the operation returns immediately after changing state. If TRUE, it waits for all active requests to complete.
      Throws:
        `AdapterInactive` - is raised if the operation is invoked on the POAManager in inactive state.

    - #### discard_requests

          void discard_requests(boolean wait_for_completion)
                         throws AdapterInactive

      This operation changes the state of the POA manager to discarding. This causes associated POAs to discard incoming requests.
      Parameters:
        `wait_for_completion` - if FALSE, the operation returns immediately after changing state. If TRUE, it waits for all active requests to complete.
      Throws:
        `AdapterInactive` - is raised if the operation is invoked on the POAManager in inactive state.

    - #### deactivate

          void deactivate(boolean etherealize_objects,
                          boolean wait_for_completion)
                   throws AdapterInactive

      This operation changes the state of the POA manager to inactive, causing associated POAs to reject the requests that have not begun executing as well as as any new requests.
      Parameters:
        `etherealize_objects` - a flag to indicate whether to invoke the etherealize operation of the associated servant manager for all active objects.
        `wait_for_completion` - if FALSE, the operation returns immediately after changing state. If TRUE, it waits for all active requests to complete.
      Throws:
        `AdapterInactive` - is raised if the operation is invoked on the POAManager in inactive state.

    - #### get_state

          State get_state()
