# Package groovy.transform

- Interface Summary
  Interface | Description
  --- | ---
  CompilationUnitAware | This interface is for AST transformations which must be aware of the compilation unit where they are applied.

- Enum Summary
  Enum | Description
  --- | ---
  AutoCloneStyle | Intended style to use for cloning when using the `@`AutoClone annotation.
  PackageScopeTarget | Intended target when `@`PackageScope is placed at the class level.
  TypeCheckingMode | This enumeration can be used whenever it is preferred to annotate a class as `TypeChecked` in general, but where only one or more methods are "dynamic".

- Annotation Types Summary
  Annotation Type | Description
  --- | ---
  ASTTest | This AST transformation aims at helping in debugging other AST transformations.
  AutoClone | Note: This annotation is currently experimental!
  AutoExternalize | Note: This annotation is currently experimental!
  Canonical | Class annotation used to assist in the creation of mutable classes.
  CompileStatic | This will let the Groovy compiler use compile time checks in the style of Java then perform static compilation, thus bypassing the Groovy meta object protocol.
  EqualsAndHashCode | Class annotation used to assist in creating appropriate `equals()` and `hashCode()` methods.
  Field | Variable annotation used for changing the scope of a variable within a script from being within the run method of the script to being at the class level for the script.
  Immutable | Class annotation used to assist in the creation of immutable classes.
  IndexedProperty | Field annotation used with properties to provide an indexed getter and setter for the property.
  InheritConstructors | Class annotation to make constructors from a super class available in a sub class.
  NotYetImplemented | Method annotation used to invert test case results.
  PackageScope | Class, method or field annotation used for turning off Groovy's auto visibility conventions.
  Synchronized | Method annotation to make a method call synchronized for concurrency handling with some useful baked-in conventions.
  ToString | Class annotation used to assist in the creation of `toString()` methods in classes.
  TupleConstructor | Class annotation used to assist in the creation of tuple constructors in classes.
  TypeChecked | This will let the Groovy compiler use compile time checks in the style of Java.
  TypeChecked.TypeCheckingInfo | This annotation is added by @TypeChecked on methods which have type checking turned on.
  WithReadLock | This annotation is used in conjunction with `WithWriteLock` to support read and write synchronization on a method.
  WithWriteLock | This annotation is used in conjunction with `WithReadLock` to support read and write synchronization on a method.
