Class ProjectorResult

Object

gudusoft.gsqlparser.ir.semantic.diff.ProjectorResult

public final class ProjectorResult
extends Object

Pure-function return type for both projectors. getReason() is non-null when the projector cannot produce a meaningful canonical model. The reporter translates a non-null reason into a single query-wide DivergenceClass.UNSUPPORTED_BY_DLINEAGE or DivergenceClass.UNSUPPORTED_BY_IR divergence.

Keeping this as data (not a thrown exception) means the comparison harness can produce a stable JSON for every corpus SQL even when one side is unsupported.
