public class UpdateOutputer

extends java.lang.Object

This sends a document containing a list of all nodes in database (just the serial number) and a compleate detail of all new or changed nodes. Normally mvg file has children of a node embeded within the nodes xml element. Also, normally fields have no serial number. The update document, however, contains all nodes at the first level in the tree - no embeded children. Also, every node has a reference to its parent, instead of the parent having a list of children. And changed fields appear separatly. To identify as new: check isnt tagged in sendNode table To identify as changed: check isnt tagged in sentNode table, or have changed node table
