org.eclipse.rdf4j.queryrender.sparql.ir.util.transform.CanonicalizeUnionBranchOrderTransform

public final class CanonicalizeUnionBranchOrderTransform
extends BaseTransform

Preserve UNION branch order while optionally normalizing inside each branch. Note: Despite the original intent expressed in earlier comments to reorder branches based on projection, the current implementation keeps original UNION branch order for textual stability and alignment with tests, and only recurses into branches to apply inner rewrites.
