gudusoft.gsqlparser.resolver2.model.ResolutionContext

public class ResolutionContext
extends Object

Global context for resolution results. Provides efficient querying and statistics about resolved columns. Design principles: 1. Reverse indexing for O(1) queries 2. Categorized storage for quick access to different resolution states 3. Statistics for monitoring resolution quality

Method Detail

registerResolution

public void registerResolution(TObjectName objName,
                               ResolutionResult result)

Register a resolution result. Called by NameResolver when a column is resolved.

public List<TObjectName> getReferencesTo(TTable table)

Get all column references to a specific table. Complexity: O(1)

Parameters:

table - Target table

Returns:

List of TObjectName referencing that table

Get all column references to a specific table.column. Complexity: O(m) where m = number of references to the table

Parameters:

table - Target table

columnName - Target column name

Returns:

List of matching TObjectName
