## Interface PolicyFactoryOperations

- All Known Subinterfaces:
    PolicyFactory

      public interface PolicyFactoryOperations

  Enables policy types to be constructed using `CORBA.ORB.create_policy`.

  A portable ORB service implementation registers an instance of the `PolicyFactory` interface during ORB initialization in order to enable its policy types to be constructed using `CORBA.ORB.create_policy`. The POA is required to preserve any policy which is registered with `ORBInitInfo` in this manner.

  See Also:
    `ORBInitInfoOperations.register_policy_factory(int, org.omg.PortableInterceptor.PolicyFactory)`

    `Policy` | `create_policy(int type, Any value)` Returns an instance of the appropriate interface derived from `CORBA.Policy` whose value corresponds to the specified any.

- - ### Method Detail

    - #### create_policy

          Policy create_policy(int type,
                               Any value)
                        throws PolicyError

      Returns an instance of the appropriate interface derived from `CORBA.Policy` whose value corresponds to the specified any.

      The ORB calls `create_policy` on a registered `PolicyFactory` instance when `CORBA.ORB.create_policy` is called for the `PolicyType` under which the `PolicyFactory` has been registered. The `create_policy` operation then returns an instance of the appropriate interface derived from `CORBA.Policy` whose value corresponds to the specified any. If it cannot, it shall throw an exception as described for `CORBA.ORB.create_policy`.

      Parameters:
        `type` - An int specifying the type of policy being created.
        `value` - An any containing data with which to construct the `CORBA.Policy`.
      Returns:
        A `CORBA.Policy`object of the specified type and value.``
      Throws:
        `PolicyError`
