Class VarNameNormalizer

java.lang.Object

org.eclipse.rdf4j.queryrender.VarNameNormalizer

public final class VarNameNormalizer
extends Object

Normalizes anonymous variable tokens so structurally identical trees compare equal even if hashed suffixes differ. Standalone identifiers only (left boundary must be a non-word char). Word chars = [A-Za-z0-9_]. Families are prefixes (including trailing underscore), e.g. "_anon_path_". Pre-numbered tails (digits-only) are preserved and reserve their numbers.
