/**
 * This interface encapsulates a single GSS-API principal entity. The
 * application obtains an implementation of this interface
 * through one of the <code>createName</code> methods that exist in the {@link
 * GSSManager GSSManager} class. Conceptually a GSSName contains many
 * representations of the entity or many primitive name elements, one for
 * each supported underlying mechanism. In GSS terminology, a GSSName that
 * contains an element from just one mechanism is called a Mechanism Name
 * (MN)<p>
 *
 * Since different authentication mechanisms may employ different
 * namespaces for identifying their principals, GSS-API's naming support is
 * necessarily complex in multi-mechanism environments (or even in some
 * single-mechanism environments where the underlying mechanism supports
 * multiple namespaces). Different name formats and their definitions are
 * identified with {@link Oid Oid's} and some standard types
 * are defined in this interface. The format of the names can be derived
 * based on the unique <code>Oid</code> of its name type.<p>
 *
 * Included below are code examples utilizing the <code>GSSName</code> interface.
 * The code below creates a <code>GSSName</code>, converts it to an MN, performs a
 * comparison, obtains a printable representation of the name, exports it
 * to a byte array and then re-imports to obtain a
 * new <code>GSSName</code>.
 * <pre>
 *      GSSManager manager = GSSManager.getInstance();
 *
 *      // create a host based service name
 *      GSSName name = manager.createName("service@host",
 *                   GSSName.NT_HOSTBASED_SERVICE);
 *
 *      Oid krb5 = new Oid("1.2.840.113554.1.2.2");
 *
 *      GSSName mechName = name.canonicalize(krb5);
 *
 *      // the above two steps are equivalent to the following
 *      GSSName mechName = manager.createName("service@host",
 *                      GSSName.NT_HOSTBASED_SERVICE, krb5);
 *
 *      // perform name comparison
 *      if (name.equals(mechName))
 *              print("Names are equals.");
 *
 *      // obtain textual representation of name and its printable
 *      // name type
 *      print(mechName.toString() +
 *                      mechName.getStringNameType().toString());
 *
 *      // export and re-import the name
 *      byte [] exportName = mechName.export();
 *
 *      // create a new name object from the exported buffer
 *      GSSName newName = manager.createName(exportName,
 *                      GSSName.NT_EXPORT_NAME);
 *
 * </pre>
 * If a security manager is installed, in order to create a {@code GSSName}
 * that contains a Kerberos name element without providing its realm,
 * a {@link javax.security.auth.kerberos.ServicePermission ServicePermission}
 * must be granted and the service principal of the permission must minimally
 * be inside the Kerberos name element's realm. For example, if the result of
 * {@link GSSManager#createName(String, Oid) createName("user", NT_USER_NAME)}
 * contains a Kerberos name element {@code user@EXAMPLE.COM}, then
 * a {@code ServicePermission} with service principal
 * {@code host/www.example.com@EXAMPLE.COM} (and any action) must be granted.
 * Otherwise, the creation will throw a {@link GSSException} containing the
 * {@code GSSException.FAILURE} error code.
