Class ImpactEngine

Object

gudusoft.gsqlparser.analyzer.v2.impact.ImpactEngine

public class ImpactEngine
extends Object

Impact analysis engine using real BFS traversal with path reconstruction.

Provides accurate graph distances (not sequential counters) and reconstructed shortest paths from source to each impacted entity.

Method Summary

Modifier and Type	Method and Description
static ImpactResult	getRoutineImpact(CallGraph callGraph, String routineId, int maxDepth) Computes routine impact: finds all routines and tables transitively affected by a change to the given routine, using forward BFS.
static ImpactResult	getTableImpact(CallGraph callGraph, String tableName, ETableAccessKind accessFilter, int maxDepth) Computes table impact: finds all routines affected by a change to the given table.

Method Detail

getRoutineImpact

public static ImpactResult getRoutineImpact(CallGraph callGraph,
                                            String routineId,
                                            int maxDepth)

Computes routine impact: finds all routines and tables transitively affected by a change to the given routine, using forward BFS.

Parameters:

callGraph - the call graph to traverse

routineId - the source routine to analyze impact from

maxDepth - maximum BFS depth (from config)

Returns:

impact result with real graph distances and reconstructed paths

getTableImpact

public static ImpactResult getTableImpact(CallGraph callGraph,
                                          String tableName,
                                          ETableAccessKind accessFilter,
                                          int maxDepth)

Computes table impact: finds all routines affected by a change to the given table. Uses reverse BFS from each direct accessor to find transitive callers.

Parameters:

callGraph - the call graph

tableName - the table name to analyze

accessFilter - optional filter (null = all access types)

maxDepth - maximum BFS depth

Returns:

impact result
