virtual MgByteReader* MgMappingService::GenerateMapUpdate | ( | MgMap * | map,
|  | INT32 | seqNo,
|  | MgDwfVersion * | dwfVersion |
| ) |  |  | `[pure virtual]`
Generates an eMap that contains any required updates to the metadata and layer graphics based on the state of the specified map. .NET Syntax
`virtual MgByteReader GenerateMapUpdate(MgMap map, int seqNo, MgDwfVersion dwfVersion);`
Java Syntax
`virtual MgByteReader GenerateMapUpdate(MgMap map, int seqNo, MgDwfVersion dwfVersion);`
PHP Syntax
`virtual MgByteReader GenerateMapUpdate(MgMap map, int seqNo, MgDwfVersion dwfVersion);`
  Parameters:
  | map | (MgMap) Map object specifying current state of map.
  | seqNo | (int) Update sequence number. An arbitrary number which is set automatically by the DWF Viewer and used by a client to identify a map update request. The client passes this number as part of its request for data, and that number is returned here so that the client can match the response with the request. The MapGuide server and the web tier do not make any use of this number except sending it back as part of the response.
  | dwfVersion | (MgDwfVersion) DWF version required by the client. This determines the schema and file versions used to generate the DWFs sent back to the client.
  Returns: Returns an MgByteReader object containing a DWF of the legend in eMap format. Exceptions:
  | MgNullArgumentException |
