java.lang.Object
org.eclipse.rdf4j.queryrender.sparql.ir.IrNode
org.eclipse.rdf4j.queryrender.sparql.ir.IrSelect
public class IrSelect extends IrNode
Textual IR for a SELECT query (header + WHERE + trailing modifiers). The WHERE body is an IrBGP. Header sections keep rendered expressions as text to preserve the exact surface form chosen by the renderer.

    • transformChildren

      public IrNode transformChildren(UnaryOperator<IrNode> op)
      Description copied from class: IrNode
      Function-style child transformation hook used by the transform pipeline to descend into nested structures. Contract: - Leaf nodes return this unchanged. - Container nodes return a new instance with their immediate children transformed using the provided operator. - Implementations must not mutate this or its existing children.
      Overrides:
      transformChildren in class IrNode

    • print

      public void print(IrPrinter p)
      Description copied from class: IrNode
      Default no-op printing; concrete nodes override.
      Specified by:
      print in class IrNode

    • getVars

      public Set<Var> getVars()
      Description copied from class: IrNode
      Collect variables referenced by this node and all of its children (if any). Default implementation returns an empty set; container and triple-like nodes override to include their own Vars and recurse into child nodes.
      Overrides:
      getVars in class IrNode

    • isDistinct

      public boolean isDistinct()

    • isReduced

      public boolean isReduced()
