Class StatementFold

Object

gudusoft.gsqlparser.lineage.v2.fold.StatementFold

public final class StatementFold
extends Object

What FOLD-V1 yields for one statement (algorithms/fold-v1.md, Section 2, item 1): the Fact Occurrences, the FactCandidates, and the requirements on every write of a field. References are the document-local refs of the document the statement was folded from.

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	StatementFold.Candidate A FactCandidate (Section 7.1, items 4 to 6) with its Occurrence.
static class	StatementFold.CandidateBinding The binding of one side of a FactCandidate Occurrence (Section 7.1, item 6).
static class	StatementFold.Decision How a reference decides a FactCandidate's candidate-set end (fold-v1 Section 7.1, item 5): the deciding reference's candidate set (in the ExplainGraph; at a published end, the document's set with the same members), and the pairs {alternative, member}, sorted.
static class	StatementFold.End One end of a FactCandidate: a fixed endpoint, or a candidate set with its membership, and, when another reference decides it (fold-v1 Section 7.1, item 5), the decision.
static class	StatementFold.FactOccurrence A Fact Occurrence (Section 8.1): the proposition, its path and ordinal, proof, bindings and support.
static class	StatementFold.Pair One (source, target) pair of an outcome (Section 7.1, item 5).
static class	StatementFold.TerminalInput A terminal input of a write (Section 7.5): its kind, disclosure, the literal or hash token, and a parameter's marker as written with, for an anonymous marker, its position (two parameters of one write are two inputs).
static class	StatementFold.WriteRequirement What a write of one field must carry (Sections 7.4 and 7.5).

Method Summary

List<StatementFold.FactOccurrence>	getFacts() One entry per Fact Occurrence (Section 8.1), ordered by source, target, label, path and ordinal.
long	getStatementRef()
List<StatementFold.WriteRequirement>	getWrites() One entry per field the statement writes (Sections 7.4 and 7.5), ordered by target.
