Class DynamicSqlEdgeProof.EdgeEvidence

Object

gudusoft.gsqlparser.dlineage.dynamicsql.DynamicSqlEdgeProof.EdgeEvidence

Enclosing class:

DynamicSqlEdgeProof

public static final class DynamicSqlEdgeProof.EdgeEvidence
extends Object

The evidence set of one candidate edge: the AST nodes whose tokens spell the source object, the target object, and the column references binding them. Callers assemble it from the sentinel parse; an edge kind whose evidence cannot be enumerated must not be offered here (fail closed by not publishing it at all).

Method Summary

Modifier and Type	Method and Description
DynamicSqlEdgeProof.EdgeEvidence	source(TParseTreeNode relation) The edge's source relation node (a TTable, an INTO clause, a derived-table node).
DynamicSqlEdgeProof.EdgeEvidence	sourceReference(TObjectName reference) A column reference on the SOURCE side: it must bind to the source relation.
DynamicSqlEdgeProof.EdgeEvidence	structure(TParseTreeNode node) An additional structural node whose span must also be literal and stable (a clause node, a join condition).
DynamicSqlEdgeProof.EdgeEvidence	target(TParseTreeNode relation) The edge's target relation node.
DynamicSqlEdgeProof.EdgeEvidence	targetReference(TObjectName reference) A column reference on the TARGET side: it must bind to the target relation.

Method Detail

source

public DynamicSqlEdgeProof.EdgeEvidence source(TParseTreeNode relation)

The edge's source relation node (a TTable, an INTO clause, a derived-table node). Mandatory. Must NOT be a TObjectName — names go through #reference so they cannot skip P3.

target

public DynamicSqlEdgeProof.EdgeEvidence target(TParseTreeNode relation)

The edge's target relation node. Mandatory. Same rule as source(gudusoft.gsqlparser.nodes.TParseTreeNode).

sourceReference

public DynamicSqlEdgeProof.EdgeEvidence sourceReference(TObjectName reference)

A column reference on the SOURCE side: it must bind to the source relation. Span-checked (P1/P2) AND binding-checked (P3).

targetReference

public DynamicSqlEdgeProof.EdgeEvidence targetReference(TObjectName reference)

A column reference on the TARGET side: it must bind to the target relation. Span-checked (P1/P2) AND binding-checked (P3).

Roles are directional on purpose: "binds to either endpoint" would certify the reverse edge, e.g. source(d).target(t) over INSERT INTO d(x) SELECT t.a FROM t.

structure

public DynamicSqlEdgeProof.EdgeEvidence structure(TParseTreeNode node)

An additional structural node whose span must also be literal and stable (a clause node, a join condition). Names must NOT come in this way — TObjectName passed here is rejected, because it would skip the P3 binding check.
