public class IndexedPropertyASTStubber extends AbstractASTTransformation
Joint-compilation stubber for IndexedProperty. Emits placeholder indexed accessors getXxx(int) and (for non-immutable fields) setXxx(int, T) so Java consumers can call them against the joint-compilation stub.

Component type detection mirrors the full transform:

  • Array fields: component type is T from T[].
  • List fields: component type is the first generic parameter, or Object if the list is raw.
  • Other field types: skipped (the full transform reports an error).

Setter emission is suppressed when the enclosing class carries an Immutable-family annotation (@Immutable, groovy.transform.ImmutableBase, or groovy.transform.KnownImmutable). The full transform's runtime guard uses field-level IMMUTABLE_BREADCRUMB metadata which isn't set until CANONICALIZATION; the class-level annotation check is a CONVERSION-time approximation that matches the typical usage pattern. Less common configurations may produce a stub that over-claims the setter — flagged in the GEP-21 spike notes.

      Description copied from interface: ASTTransformation
      The method is invoked when an AST Transformation is active. For local transformations, it is invoked once each time the local annotation is encountered. For global transformations, it is invoked once for every source unit, which is typically a source file.
      Parameters:
      nodes - The ASTnodes when the call was triggered. Element 0 is the AnnotationNode that triggered this annotation to be activated. Element 1 is the AnnotatedNode decorated, such as a MethodNode or ClassNode. For global transformations it is usually safe to ignore this parameter.
      source - The source unit being compiled. The source unit may contain several classes. For global transformations, information about the AST can be retrieved from this object.
