GraphBasedDbRowOpSorter (cayenne-doc: Cayenne Documentation 5.0-M2 API)
Description: declaration: package: org.apache.cayenne.access.flush.operation, class: GraphBasedDbRowOpSorter

# Class GraphBasedDbRowOpSorter

java.lang.Object
org.apache.cayenne.access.flush.operation.GraphBasedDbRowOpSorter

All Implemented Interfaces:
  `DbRowOpSorter`

public class GraphBasedDbRowOpSorter extends Object implements DbRowOpSorter
Db operation sorted that builds dependency graph and uses topological sort to get final order. This in general slower than `DefaultDbRowOpSorter` but can handle more edge cases (like multiple meaningful PKs/FKs). TODO: possible optimizations could be optional logic parts (e.g. detecting effective id intersections, reflexive dependencies, etc.)

Since:
  4.2
