Class InsertRowManager

java.lang.Object
  org.deegree.feature.persistence.sql.insert.InsertRowManager

public class InsertRowManager
extends Object

Performs inserts in courtesy of the SQLFeatureStoreTransaction.

The strategy aims for:

• Streaming / low memory footprint
• Feature references must not be resolved
• Usability for complex structures / mappings
• Auto-generated columns (feature ids)
• Forward xlink references
• Backward xlink references

TODO strategy for cyclic foreign keys (at least detection)
