Detailed Description

CORBA Name/value pair implementation.

These occur only in "NVList" (named value list) data structures. The binary form of the data structure is frozen and visible to programs using it (e.g. from C). The C++ class supports some programming discipline, e.g. to avoid memory leaks. They just represent parameters to calls. The name is optional, and the value is packaged as an Any. The flags indicate parameter mode, and some ownership rules for "top level" memory.

Constructor & Destructor Documentation

CORBA::NamedValue::~NamedValue ( void ) [protected]

Destructor.

Protected destructor to enforce proper memory management through the reference counting mechanism.

      this->name_ = 0;
    }
  // the any will be destroyed by itself
}

CORBA::NamedValue::NamedValue ( void ) [private]

private constructor. Cannot be directly instantiated other than by its friends.
