public class EndPointsIPv4
extends EndPoints

Represents a PCEP END-POINTS object IPv4 Type, as defined in RFC 5440

From RFC 5440 Section 7.6. END-POINTS Object

 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.

   Note that the source and destination addresses specified in the END-
   POINTS object may correspond to the source and destination IP address
   of the TE LSP or to those of a path segment.  Two END-POINTS objects
   (for IPv4 and IPv6) are defined.

   END-POINTS Object-Class is 4.

   END-POINTS Object-Type is 1 for IPv4 and 2 for IPv6.

   The format of the END-POINTS object body for IPv4 (Object-Type=1) is
   as follows:

       0                   1                   2                   3
       0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
