Constructor Detail

ORB

public ORB()

Orb instances must be created through ORB.init

Method Detail

setFeature

public void setFeature(java.lang.String feature,
                       java.lang.Object reference)

This operation is used to set an OpenORB feature reference.

getFeature

public java.lang.Object getFeature(java.lang.String feature)

This operation is used to get an OpenORB feature reference.

getLoader

public ORBLoader getLoader()

This operation returns the configurator used by this ORB instance

getPICurrent

public CurrentImpl getPICurrent()

Returns the PICurrent implementation. The PICurrent must be resolved with every invocation both at the client and server end, so it's avalable from this operation for optimization reasons.

addInitialReference

public void addInitialReference(java.lang.String name,
                                Object target)

Register an initial reference.

                                  ServiceInformation service_information)

Add service information
