of GroovyObject. |

value and working up towards some ending (or to) value.

| GroovySystem | |
| IntRange | Represents a list of Integer objects starting at a specified from value up (or down)
to and potentially including a given to value. |
| ListWithDefault | A wrapper for List which automatically grows the list when either get(int) or
getAt(int) is called with an index greater than or equal to size(). |
| MapWithDefault | A wrapper for Map which allows a default value to be specified. |
| MetaArrayLengthProperty | Represents the length property of an array |
| MetaBeanProperty | Represents a property on a bean which may have a getter and/or a setter |
| MetaClassImpl | Allows methods to be dynamically added to existing classes at runtime |
| MetaClassImpl.Index | |
| MetaClassImpl.MetaConstructor | This is a helper class introduced in Groovy 2.1.0, which is used only by indy. |
| MetaClassRegistry.MetaClassCreationHandle | Class used as base for the creation of MetaClass implementations. |
| MetaClassRegistryChangeEvent | An event used to propagate meta class updates |
| MetaExpandoProperty | Represents a property in an Expando object |
| MetaMethod | Represents a Method on a Java object a little like Method except without using reflection to invoke the method |
| MetaProperty | Represents a property on a bean which may have a getter and/or a setter |
| NonEmptySequence | Represents a sequence of one or more objects of a given type. |
| NumberRange | Represents an immutable list of Numbers from a value to a value with a particular step size. |
| ObjectRange | Represents an inclusive list of objects from a value to a value using comparators. |
| ParameterArray | Distinguish a parameter array from Object[]. |
| PropertyValue | |
| ProxyMetaClass | As subclass of MetaClass, ProxyMetaClass manages calls from Groovy Objects to POJOs. |
| Reference | Represents a reference to a value |
| Script | This object represents a Groovy script |
| Sequence | Represents a sequence of zero or more objects of a given type. |
| SpreadMap | Helper to turn a list with an even number of elements into a Map. |
| TracingInterceptor | |
| Tuple | Represents a list of Objects. |
| Tuple1 | Represents a list of 1 typed Object. |
| Tuple2 | Represents a list of 2 typed Objects. |
| Tuple3 | Represents a list of 3 typed Objects. |
| Tuple4 | Represents a list of 4 typed Objects. |
| Tuple5 | Represents a list of 5 typed Objects. |
| Tuple6 | Represents a list of 6 typed Objects. |
| Tuple7 | Represents a list of 7 typed Objects. |
| Tuple8 | Represents a list of 8 typed Objects. |
| Tuple9 | Represents a list of 9 typed Objects. |
| Exception | Description |
|---|---|
| ClosureException | An exception thrown by a closure invocation |
| DeprecationException | Use this exception to mark a method implementation as being deprecated. |
| GroovyRuntimeException | An exception thrown by the interpreter |
| IllegalPropertyAccessException | An exception occurred if a dynamic property dispatch fails with a field not accessible. |

| Annotation Type | Description |
|---|---|
| Category | Transforms an instance-style Groovy class or interface to become a static-style conventional Groovy category. |
| Delegate | Annotation to automatically delegate part of the functionality of an owner class to the annotated delegation target. |
| DelegatesTo | This annotation can be used by API or DSL writers to document parameters which accept a closure. |
| DelegatesTo.Target | Parameter annotation used to specify the delegate for a @DelegatesTo annotated
parameter of the same method. |
| Grab | Used to grab the referenced artifact and its dependencies and make it available on the Classpath. |
| GrabConfig | Used to modify the grape configuration for grab requests. |
| GrabExclude | Used to exclude an indirectly referenced artifact (a transitive dependency) from the classpath. |
| GrabResolver | Used to add a repository for resolving Grape dependencies. |
| Grapes | Sometimes we will need more than one grab per class, but we can only add one annotation type per annotatable node. |
| Lazy | Field annotation to simplify lazy initialization. |
| Mixin | Provides a mechanism for mixing in methods into a class. |
| Newify | Annotation that supports writing constructor call expressions without the 'new' keyword. |
| Singleton | Class annotation to make a singleton class. |
