Class TupleExprToIrConverter

java.lang.Object

org.eclipse.rdf4j.queryrender.sparql.TupleExprToIrConverter

@Experimental
public class TupleExprToIrConverter
extends Object

Extracted converter that builds textual-IR from a TupleExpr. This class mirrors the TupleExpr→IR logic originally embedded in TupleExprIRRenderer; the renderer now delegates to this converter to build IR, and handles printing separately.

 TupleExprIRRenderer r,
 boolean applyTransforms)

Build IrSelect (raw). The applyTransforms argument is ignored; transforms are handled by the renderer.

hasExplicitRootScope

public static boolean hasExplicitRootScope(TupleExpr root)

Public helper for renderer: whether the normalized root has explicit scope change.
