Class DbMappingScanSqlScript

java.lang.Object
  smacs.load.mapping.DbMappingScanSqlScript

public class DbMappingScanSqlScript

extends Object

the main class.

This class is being given an sql syntaxtree where it looks for any nodes of interest for the transformation subsystem. Upon instantion a "store" is given where any scanned transformation is being pushed via "addTransform()". Per default the wrapped DbMappingTransformStore is a DbMappingTransformListNode.

The parser's sql-tree might have very different way to define a transformation but each is mapped into a new instance of supertype DbMappingTransform (per default an instance of DbMappingTransformNode). This has a field-list, a target-table, conditions and so on - plus a few hint-markers. Among them we do also find the target-operation variations as isInsert/isUpdate/isExists - expressing each a group of the possible insert syntax possibilities.
