Class CrossRefSelins

java.lang.Object
  smacs.find.imports.CrossRefSelins

public class CrossRefSelins

extends Object

bind seletected items of a Selins to its DDL declarations.

An important step into the internal format is the detection of the attributes of the selected items in select-insert statement. This includes not only its type but also the crossreferences to other columsn and tables - while this is of minor importance on the QUERY side of the transfer it turns out to be paramount on the UPDATE side of the transfer where possibly SERIAL UNIQUE identifiers are used or PRIMARY KEY conditions must be met.

The actual implementation annotates again in xml style with assigning reference ids and attributes between the matching parts of a tree. That allows us later to assign global identifiers for each item while generation a java script, and each of the references gets updated automatically when catching the name by dereferencing the crossref attribute.

The actual parsing of an import module is done with the prior work of a ModuleImport that sits on top of the DDL table import and the SelIns import.
