  ErrorCollecting | An AST transform with the ability to report errors.
  LogASTTransformation.LoggingStrategy | A LoggingStrategy defines how to wire a new logger instance into an existing class.
  LogASTTransformation.LoggingStrategyV2 | A LoggingStrategy defines how to wire a new logger instance into an existing class.
  TransformWithPriority | AST transforms may optionally implement this interface and return a priority value.

- Class Summary
  Class | Description
  --- | ---
  ASTTestTransformation | Implements ASTTest by scheduling the supplied test closure across compilation phases.
  ASTTransformationCollectorCodeVisitor | Walks the AST and collects references to annotations that are annotated themselves by GroovyASTTransformation.
  ASTTransformationVisitor | This class handles the invocation of the ASTAnnotationTransformation when it is encountered by a tree walk.
  AbstractASTTransformation |
  AbstractInterruptibleASTTransformation | Base class for AST Transformations which will automatically throw an InterruptedException when some conditions are met.

  BuilderASTTransformation.AbstractBuilderStrategy |
  BuilderASTTransformation.AbstractBuilderStrategy.PropertyInfo |
  CategoryASTTransformation | Handles generation of code for the Category: annotation.
  CompileDynamicProcessor |
  ConditionalInterruptibleASTTransformation | Allows "interrupt-safe" executions of scripts by adding a custom conditional check on loops (for, while, do) and first statement of closures.

  LogASTTransformation.AbstractLoggingStrategyV2 |
  MapConstructorASTTransformation | Handles generation of code for the MapConstructor: annotation.
  MemoizedASTTransformation | Handles generation of code for the Memoized annotation.
  NamedVariantASTTransformation |
  NewifyASTTransformation | Handles generation of code for the `@Newify` AST transform.
  NonSealedASTTransformation | Handles generation of code for the Sealed: annotation.

  StaticTypesTransformation | Handles the implementation of the TypeChecked transformation.
  SynchronizedASTTransformation | Handles generation of code for the `@Synchronized` annotation.
  ThreadInterruptibleASTTransformation | Allows "interrupt-safe" executions of scripts by adding Thread.currentThread().isInterrupted() checks on loops (for, while, do) and first statement of closures.
  TimedInterruptibleASTTransformation | Allows "interrupt-safe" executions of scripts by adding timer expiration checks on loops (for, while, do) and first statement of closures.
