public class LazyASTStubber
extends AbstractASTTransformation

Joint-compilation stubber for Lazy. Aligns the stub's accessor surface with what the full LazyASTTransformation produces at SEMANTIC_ANALYSIS: a getter only, no setter.

How: mark the @Lazy property as final at CONVERSION. The stub generator runs through Verifier.visitProperty, which auto-generates a setter only when the property is neither private nor final. Marking it final therefore suppresses setter emission in the stub. The full transform later removes the property entirely (replacing it with a private backing field plus an explicit getter), so the final flag does not survive into the runtime class.

public void visit(ASTNode[] nodes,
 SourceUnit source)

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.
