<module>lname</module>
<modulesummary>Interface that supports the name pseudo-objects.</modulesummary>
<description>
<p>This interface is a part of the names library which is used to hide the
representation of names. In Orbers Erlang mapping the pseudo-object names
and the real IDL names have the same representation but it is desirable that
the clients uses the names library so they will not be dependent of the representation.
The lname interface supports handling of names e.g. adding and removing name
components.</p>
<p>Note that the lname interface in orber does not contain a destroy function because
the Names are represented as standard Erlang lists and therefor will be removed
by the garbage collector when not in use.</p>
<p>The type <c>NameComponent</c> used below is defined as:</p>
<code type="erl">
-record('CosNaming_NameComponent', {id, kind=""}).
</code>
<p><c>id</c> and <c>kind</c> are strings. </p>
<p>The record is defined in the file <c>CosNaming.hrl</c> and it
is included with:</p>
<code type="erl">
-include_lib("orber/COSS/CosNaming/CosNaming.hrl").
</code>
