Local interfaces are implemented by using CORBA::LocalObject - * to provide implementations of {@code Object} pseudo - * operations and any other ORB-specific support mechanisms that are - * appropriate for such objects. Object implementation techniques are - * inherently language-mapping specific. Therefore, the - * {@code LocalObject} type is not defined in IDL, but is specified - * in each language mapping. - *
Methods that do not apply to local objects throw - * an {@code org.omg.CORBA.NO_IMPLEMENT} exception with the message, - * "This is a locally contrained object." Attempting to use a - * {@code LocalObject} to create a DII request results in NO_IMPLEMENT - * system exception. Attempting to marshal or stringify a - * {@code LocalObject} results in a MARSHAL system exception. Narrowing - * and widening references to {@code LocalObjects} must work as for regular - * object references. - *
{@code LocalObject} is to be used as the base class of locally
- * constrained objects, such as those in the PortableServer module.
- * The specification here is based on the CORBA Components
- * Volume I - orbos/99-07-01
