public class GeneralizedEndPoints
extends EndPoints

Base abstract class for representing Generalized EndPoints Object.

It will follow draft-ietf-pce-gmpls-pcep-extensions-01 and GEYSERS network service paradigms

ESTE LO HE REPETIDO PARA CADA SERVICIO DE CONECTIVIDAD GEYSERS  
 The END-POINTS object is used in a PCReq message to specify the
 source IP address and the destination IP address of the path for
 which a path computation is requested.  The P flag of the END-POINTS
 object MUST be set.  If the END-POINTS object is received with the P
 flag cleared, the receiving peer MUST send a PCErr message with
  Error-Type=10 and Error-value=1.  The corresponding path computation
   request MUST be cancelled by the PCE without further notification.
   
   A new Object Type is defined
  to address the following possibilities:

  o  Different endpoint types.

  o  Label restrictions on the endpoint.

  o  Specification of unnumbered endpoints type as seen in GMPLS
     networks.

 The Object is encoded as follow:

      0                   1                   2                   3

      |                                                               |
      ~                           TLVs                                ~
      |                                                               |
      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+


   Reserved bits should be set to 0 when a message is sent and ignored
   when the message is received

   the endpoint type is defined as follow:

   Value   Type                Meaning

   0       Point-to-Point

   1       Point-to-Multipoint New leaves to add

   2                           Old leaves to remove

   3                           Old leaves whose path can be
                               modified/reoptimized

   4                           Old leaves whose path must be left
                               unchanged

   
 In GEYSERS the endpoint type field in the END-POINTS object will 
 indicate the paradigm type (assisted unicast, restricted anycast,
 full anycast) while the TLV type could indicate IPv4, IPv6, NSAP,
 storage description, server description or application description.
