Description
AnnotationCollector
The AnnotationCollector can be used to define aliases for groups of annotations.
ASTTest
This AST transformation aims at helping in debugging other AST transformations.
AutoClone
Class annotation used to assist in the creation of `Cloneable` classes.
AutoCloneStyle
Intended style to use for cloning when using the `@`AutoClone annotation.
BaseScript
Variable annotation used for changing the base script class of the current script.
Canonical
Class annotation used to assist in the creation of mutable classes.
CompilationUnitAware
This interface is for AST transformations which must be aware of the compilation unit where they are applied.
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.
ExternalizeMethods
Class annotation used to assist in the creation of `Externalizable` classes.
ExternalizeVerifier
Class annotation used to assist in the creation of `Externalizable` classes.
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.
Memoized
Method annotation that creates a cache for the results of the execution of the annotated method.
NotYetImplemented
Method annotation used to invert test case results.
PackageScope
Annotation used for turning off Groovy's auto visibility conventions.
PackageScopeTarget
Intended target when `@`PackageScope is placed at the class level.
SelfType
This annotation can be added on a trait to declare the list of types that a class implementing that trait is supposed to extend.
Sortable
A class annotation used to make a class Comparable by multiple Comparators.
SourceURI
Variable annotation used for getting the URI of the current script.
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.
Trait
Used to mark a class as being a trait.
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.
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".
Undefined
Java doesn't allow you to have null as an attribute value.
Undefined.CLASS
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.
