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.

Method Summary

Modifier and Type	Method and Description
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.

Throws:

PolicyError

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.
